Clean Water Rights


Clean Water Act is the primary federal law in the United States governing water pollution. Its objective is to restore and maintain the chemical, physical, and biological integrity of the nation's waters by preventing point and nonpoint pollution sources, providing assistance to publicly owned treatment works for the improvement of wastewater treatment, and maintaining the integrity of wetlands.

Neurotoxin are toxins that are poisonous or destructive to nerve tissue (causing neurotoxicity).
Neurotoxicity when exposure to natural or artificial toxic substances, which are called neurotoxins, alters the normal activity of the nervous system in such a way as to cause damage to nervous tissue. This can eventually disrupt or even kill neurons, key cells that transmit and process signals in the brain and other parts of the nervous system.

Fresh Water from the Air
Water Generator
Atmospheric Water Generator is a device that extracts water from humid ambient air. Water vapor in the air is condensed by cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air. Unlike a dehumidifier, an AWG is designed to render the water potable. AWGs are useful where pure drinking water is difficult or impossible to obtain, because there is almost always a small amount of water in the air that can be extracted. The two primary techniques in use are cooling and desiccants.

Dryland Farming are agricultural techniques for non-irrigated cultivation of crops. Dryland farming is associated with drylands - dry areas characterized by a cool wet season followed by a warm dry season.
Desert Farming generally relies on irrigation, as it is the easiest way to make a desert bloom. In California, the Imperial Valley is a good example of what can be done. Australia and the Horn of Africa are also places with interesting desert agriculture.
Tropical Agriculture common terms would include the humid-tropics (rainforests); the arid-tropics (deserts and dry areas); or monsoon zones (those areas that have well defined wet/dry seasons and experience monsoons). Such labeling is very useful when discussing agriculture, because what works in one area of the world will normally work in a similar area somewhere else, even if that area is on the opposite side of the globe.

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation. Leaf surfaces are dotted with pores called stomata, and in most plants they are more numerous on the undersides of the foliage. The stomata are bordered by guard cells and their stomatal accessory cells (together known as stomatal complex) that open and close the pore. Transpiration occurs through the stomatal apertures, and can be thought of as a necessary "cost" associated with the opening of the stomata to allow the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants, changes osmotic pressure of cells, and enables mass flow of mineral nutrients and water from roots to shoots. Two major factors influence the rate of water flow from the soil to the roots: the hydraulic conductivity of the soil and the magnitude of the pressure gradient through the soil. Both of these factors influence the rate of bulk flow of water moving from the roots to the stomatal pores in the leaves via the xylem.
Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. The other type of vaporization is boiling, which is characterized by bubbles of saturated vapor forming in the liquid phase. Steam produced in a boiler is another example of evaporation occurring in a saturated vapor phase. Evaporation that occurs directly from the solid phase below the melting point, as commonly observed with ice at or below freezing or moth crystals (napthalene or paradichlorobenzene), is called sublimation, which is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.
Evapotranspiration is the sum of evaporation and plant transpiration from the Earth's land and ocean surface to the atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves. Evapotranspiration is an important part of the water cycle. An element (such as a tree) that contributes to evapotranspiration can be called an evapotranspirator.

Semiarid Agriculture
Semi-Arid-Climates
Semi-arid Climate is the climate of a region that receives precipitation below potential evapotranspiration, but not extremely. There are different kinds of semi-arid climates, depending on such variables as temperature, and they give rise to different classes of ecology.
Köppen Climate Zone Classification is one of the most widely used climate classification systems.

Dry Climate Agriculture
Drought is a period of below-average precipitation in a given region, resulting in prolonged shortages in its water supply, whether atmospheric, surface water or ground water. A drought can last for months or years, or may be declared after as few as 15 days. It can have a substantial impact on the ecosystem and agriculture of the affected region and harm to the local economy. Annual dry seasons in the tropics significantly increase the chances of a drought developing and subsequent bush fires. Periods of heat can significantly worsen drought conditions by hastening evaporation of water vapour.
Desert is a barren area of land where little precipitation occurs and consequently living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one third of the land surface of the world is arid or semi-arid. This includes much of the polar regions where little precipitation occurs and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location.
Arid is characterized by a severe lack of available water, to the extent of hindering or preventing the growth and development of plant and animal life. Environments subject to arid climates tend to lack vegetation and are called xeric or desertic. Most "arid" climates surround the equator; these places include most of Africa and parts of South America, Central America and Australia.
Trees
Arable Land is land capable of being ploughed and used to grow crops. In Britain, it was traditionally contrasted with pasturable lands such as heaths which could be used for sheep-rearing but not farmland.
Erosion is the action of surface processes (such as water flow or wind) that remove soil, rock, or dissolved material from one location on the Earth's crust, then transport it away to another location. The particulate breakdown of rock or soil into clastic sediment is referred to as physical or mechanical erosion; this contrasts with chemical erosion, where soil or rock material is removed from an area by its dissolving into a solvent (typically water), followed by the flow away of that solution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres.

How we can make Crops Survive without Water (video and text)
Resurrection Plant is any poikilohydric plant that can survive extreme dehydration, even over months or years.
Poikilohydry is the lack of ability (structural or functional mechanism) to maintain and/or regulate water content to achieve homeostasis of cells and tissue connected with quick equilibration of cell/tissue water content to that of the environment. Frequently, it is coupled with the capacity to tolerate dehydration to low cell or tissue water content and to recover from it without physiological damage. This condition occurs in such organisms as the lichens and bryophytes that lack mechanisms, such as a waterproofing cuticle and stomata that can help to prevent desiccation. Poikilohydry is also noted in many forms of algae, which may be able to survive desiccation between successive high tides, or during occasional stranding due to the drying of a lake or pond. Similarly, poikilohydry occurs in land plants which survive environmental conditions when water supplies are seasonal or intermittent, as in the liverwort genus Targionia, which lives in Mediterranean habitats with hot dry summers.

Transcriptome is the set of all messenger RNA molecules in one cell or a population of cells. It differs from the exome in that it includes only those RNA molecules found in a specified cell population, and usually includes the amount or concentration of each RNA molecule in addition to the molecular identities.
Proteome is the entire set of proteins expressed by a genome, cell, tissue, or organism at a certain time. More specifically, it is the set of expressed proteins in a given type of cell or organism, at a given time, under defined conditions. The term is a blend of proteins and genome. Proteomics is the study of the proteome.
Lipidome refers to the totality of lipids in cells. Lipids are one of the four major molecular components of biological organisms, along with proteins, sugars and nucleic acids.
Promoter (genetics) is a region of DNA that initiates transcription of a particular gene. Promoters are located near the transcription start sites of genes, on the same strand and upstream on the DNA (towards the 5' region of the sense strand). Promoters can be about 100–1000 base pairs long.
Abscisic acid lays an important part in plant responses to environmental stress in response to decreased soil water potential
Water Potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects such as capillary action (which is caused by surface tension).

Hydrogeologist – Groundwater Hydrologist A groundwater hydrologist is a hydrologist who specializes in atmospheric and surface/subsurface interactions. Hydrogeologists typically train in departments of geology whereas groundwater hydrologists usually study within engineering departments, although interdisciplinary programs are becoming more common. Hydrogeologists
and groundwater hydrologists and engineers evaluate the quantity, quality, reliability, and sustainability of all aspects of groundwater assessment, management, and development.
Hydrology is the scientific study of the movement, distribution, and quality of water on Earth and other planets, including the water cycle, water resources and environmental watershed sustainability. A practitioner of hydrology is a hydrologist, working within the fields of earth or environmental science, physical geography, geology or civil and environmental engineering. Hydrology subdivides into surface water hydrology, groundwater hydrology (hydrogeology), and marine hydrology. Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage-basin management and water quality, where water plays the central role. Oceanography and meteorology are not included because water is only one of many important aspects within those fields. Hydrological research can inform environmental engineering, policy and planning.
Infiltration (hydrology) is the process by which water on the ground surface enters the soil. Infiltration rate in soil science is a measure of the rate at which soil is able to absorb rainfall or irrigation. It is measured in inches per hour or millimeters per hour. The rate decreases as the soil becomes saturated. If the precipitation rate exceeds the infiltration rate, runoff will usually occur unless there is some physical barrier. It is related to the saturated hydraulic conductivity of the near-surface soil. The rate of infiltration can be measured using an infiltrometer, which is a device used to measure the rate of water infiltration into soil or other porous media. Commonly used infiltrometers are single ring or double ring infiltrometer, and also disc permeameter, which is a field instrument used for measuring water infiltration in the soil, which is characterized by in situ saturated and unsaturated soil hydraulic properties. It is mainly used to provide estimates of the hydraulic conductivity of the soil near saturation.

Holistic Management is a systems thinking approach to managing resources that was originally developed by Allan Savory for reversing desertification.
Rangeland are grasslands, shrublands, woodlands, wetlands, and deserts that are grazed by domestic livestock or wild animals. Types of rangelands include tallgrass and shortgrass prairies, desert grasslands and shrublands, woodlands, savannas, chaparrals, steppes, and tundras. Rangelands do not include forests lacking grazable understory vegetation, barren desert, farmland, or land covered by solid rock, concrete and/or glaciers.
Grazing is a method of feeding in which a herbivore feeds on plants such as grasses, or other multicellular organisms such as algae. In agriculture, grazing is one method used whereby domestic livestock are used to convert grass and other forage into meat, milk and other products.

Natural Sequence Farming is a method of landscape regeneration that involves implementing major earthworks on a given area of land that has been devastated by deforestation and general agricultural activities, to emulate the role of natural watercourses in an effort to reverse salinity, slow erosion and increase soil and water quality to enable native vegetation to regenerate and restore the riparian zone. The method does not require the use of artificial fertilisers or herbicides.

Drip Irrigation is a form of irrigation that saves water and fertilizer by allowing water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done through narrow tubes that deliver water directly to the base of the plant. It is chosen instead of surface irrigation for various reasons, often including concern about minimizing evaporation.
Drip Irrigation Tools
Irrigation is the method in which a controlled amount of water is supplied to plants at regular intervals for agriculture. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Additionally, irrigation also has a few other uses in crop production, which include protecting plants against frost, suppressing weed growth in grain fields and preventing soil consolidation. In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dry land farming. Irrigation systems are also used for dust suppression, disposal of sewage, and in mining. Irrigation is often studied together with drainage, which is the natural or artificial removal of surface and sub-surface water from a given area.
Irrigation
Soil
Swale Landform is a low tract of land, especially one that is moist or marshy. The term can refer to a natural landscape feature or a human-created one. Artificial swales are often designed to manage water runoff, filter pollutants, and increase rainwater infiltration.

North of the 49th parallel of latitude. Productive farming, therefore, depends on crops that ripen early, if they are spring sown, or are winter hardy, if they are winter annuals, biennials or perennials.
Crops can be classified in several ways. By growth habit they are annual, biennial or perennial, depending on whether they complete their life cycle in one or two years, or persist for over two years. The special term "winter annuals" is used for crops that are planted and germinate in fall, spend winter in a dormant state, renew growth in spring and are harvested in July or August,

Climate-related threats to global food production include risks to grain, vegetable, and fruit crops, livestock, and fisheries.
Climate change and Food Security

United Nations Environment Programme (UNEP) says that crops such as wheat and maize are generating more potential toxins as a reaction to protect themselves from extreme weather. These chemical compounds are harmful to people and animals if consumed for a prolonged period of time. Under normal conditions, for instance, plants convert nitrates they absorb into nutritious amino acids and proteins. But prolonged drought slows or prevents this conversion, leading to more potentially problematic nitrate accumulating in the plant. If people eat too much nitrate in their diets, it can interfere with the ability of red blood cells to transport oxygen in the body, Crops susceptible to accumulating too much nitrate in times of stress include maize, wheat, barley, soybeans, millet and sorghum. Some drought-stressed crops, when then exposed to sudden large amounts of rain that lead to rapid growth, in turn accumulate hydrogen cyanide, more commonly known as prussic acid. Prussic acid - one of the ingredients used in some types of chemical warfare - interferes with oxygen flow in humans. Plants such as cassava, flax, maize and sorghum are most vulnerable to dangerous prussic acid accumulation. Cases of nitrate or hydrogen cyanide poisoning in humans were reported in Kenya in 2013 and in the Philippines in 2005. Aflatoxins, molds that can affect plant crops and raise the risk of liver damage, cancer and blindness, as well as stunting foetuses and infants. About 4.5 billion people in developing countries are exposed to aflatoxins each year Toxic crops can lead to neurological diseases among humans but the greatest challenge is the incidence of cancer. Research centers with the Consultative Group on International Agricultural Research are developing seeds that are suitable in various regions that have been hit by climate change.


Rain


Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated—that is, become heavy enough to fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems, as well as water for hydroelectric power plants and crop irrigation.
Surface Runoff is the flow of water that occurs when excess stormwater, meltwater, or other sources flows over the Earth's surface. This might occur because soil is saturated to full capacity, because rain arrives more quickly than soil can absorb it, or because impervious areas (roofs and pavement) send their runoff to surrounding soil that cannot absorb all of it. Surface runoff is a major component of the water cycle. It is the primary agent in soil erosion by water.

Snowpack forms from layers of snow that accumulate in geographic regions and high altitudes where the climate includes cold weather for extended periods during the year. Snowpacks are an important water resource that feed streams and rivers as they melt. Therefore, snowpacks are both the drinking water source for many communities and a potential source of flooding (in case of sudden melting). Snowpacks also contribute mass to glaciers in their accumulation zone.
Snowmelt is surface runoff produced from melting snow. It can also be used to describe the period or season during which such runoff is produced. Water produced by snowmelt is an important part of the annual water cycle in many parts of the world, in some cases contributing high fractions of the annual runoff in a watershed. Predicting snowmelt runoff from a drainage basin may be a part of designing water control projects. Rapid snowmelt can cause flooding. If the snowmelt is then frozen, very dangerous conditions and accidents can occur, introducing the need for salt to melt the ice.
Ice
Meltwater  is water released by the melting of snow or ice, including glacial ice, tabular icebergs and ice shelves over oceans. Meltwater is often found in the ablation zone of glaciers, where the rate of snow cover is reducing. Meltwater can be produced during volcanic eruptions, in a similar way in which the more dangerous lahars form.
Blood Rain is a phenomenon in which blood is perceived to fall from the sky in the form of rain.  
Haematococcus Pluvialis is a freshwater species of Chlorophyta from the family Haematococcaceae. This species is well known for its high content of the strong antioxidant astaxanthin, which is important in aquaculture, and cosmetics. Often responsible for the blood-red colour seen in the bottom of dried out rock pools and bird baths.

Water Use it Wisely
Water Conservation includes all the policies, strategies and activities made to sustainably manage the natural resource fresh water, to protect the water environment, and to meet current and future human demand. Population, household size, and growth and affluence all affect how much water is used. Factors such as climate change have increased pressures on natural water resources especially in manufacturing and agricultural irrigation. Many US cities have already implemented policies aimed at water conservation, with much success. The goals of water conservation efforts include: Ensuring availability of water for future generations where the withdrawal of freshwater from an ecosystem does not exceed its natural replacement rate. Energy conservation as water pumping, delivery and wastewater treatment facilities consume a significant amount of energy. In some regions of the world over 15% of total electricity consumption is devoted to water management. Habitat conservation where minimizing human water use helps to preserve freshwater habitats for local wildlife and migrating waterfowl, but also water quality. The key activities that benefit water conservation are as follows : Any beneficial reduction in water loss, use and waste of resources. Avoiding any damage to water quality. Improving water management practices that reduce the use or enhance the beneficial use of water.

Water Management is the activity of planning, developing, distributing and managing the optimum use of water resources. It is a sub-set of water cycle management. Ideally, water resource management planning has regard to all the competing demands for water and seeks to allocate water on an equitable basis to satisfy all uses and demands. As with other resource management, this is rarely possible in practice.
Watershed Management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs, and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within a watershed boundary. Features of a watershed that agencies seek to manage include water supply, water quality, drainage, stormwater runoff, water rights, and the overall planning and utilization of watersheds. Landowners, land use agencies, stormwater management experts, environmental specialists, water use surveyors and communities all play an integral part in watershed management.

Water Storage Tanks
Water Storage Tanks
Water Tank is a container for storing water. The need for a water tank is as old as civilization, to provide storage of water for use in many applications, drinking water, irrigation agriculture, fire suppression, agricultural farming, both for plants and livestock, chemical manufacturing, food preparation as well as many other uses. Water tank parameters include the general design of the tank, and choice of construction materials, linings. Various materials are used for making a water tank: plastics (polyethylene, polypropylene), fiberglass, concrete, stone, steel (welded or bolted, carbon, or stainless). Earthen pots also function as water storages. Water tanks are an efficient way to help developing countries to store clean water.

Water Purification Process (City)


The first step of water purification is called Coagulation. Like blood forming a scab, the alum helps to chunk up the organic material in the water, so it can fall to the bottom of the tank. It works because alum—also known as Aluminum Sulfate—has a positive charge, whereas the organic gunk floating in the water tends to be negatively charged. They stick together and form a solid, which falls out of the water in a process called Sedimentation. Then the now clear water goes through the filtration
step, where it wends its way through several layers of sand, gravel, and charcoal. This removes much of the smaller particles. In the last step, it’s treated with Chloramines to kill bacteria and other microorganisms, giving the water its faintly stinky swimming pool smell. The techniques to treat its drinking water are used around the world, and those methods have proven successful so far.

They are supposed to test for a wide gamut of potentially harmful contaminants. Some of these include naturally occurring microorganisms, such as Cryptosporidium and Coliform Bacteria; metals such as Barium, Copper, Lead; and Herbicides such as atrazine. Drinking water treatment plants in the U.S. are supposed to publish a water quality report every year, noting contaminates that were present above the detection level. In total, the EPA requires drinking water treatment plants to test for almost 90 different contaminants. But noticeably absent from this list are any type of drug or pharmaceutical.

2.5 billion people around the world currently lack access to improved sanitation, and 27 percent of urban dwellers in developing nations do not have access to piped water in their homes. Every day, around 2 million tons of human waste are disposed of in water channels.

The World Health Organization reports that 3.4 million people—mainly children—die each year from water-related diseases like cholera, dysentery, or typhoid.

The EPA estimates anywhere from 23,000 to 75,000 overflows of sanitary-sewer systems each year in the U.S.

The right infrastructure becomes critical in preserving water quality and preventing a shortage of clean drinking water. Unfortunately, most of the technology employed by cities today lags behind the latest innovations.  Toilets

Water Basics


Water H2O (wiki)
There are 3 Atoms in a Water Molecule, 2 hydrogen atoms (H), and 1 oxygen atom (O)

Condensation is the change of the physical state of matter from gas phase into liquid phase, and is the reverse of evaporation. The word most often refers to the water cycle. It can also be defined as the change in the state of water vapour to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within the atmosphere. When the transition happens from the gaseous phase into the solid phase directly, the change is called deposition.

Dew Point is the temperature at which a given concentration of water vapor in air will form dew. More specifically it is a measure of atmospheric moisture. It is the temperature to which air must be cooled at constant pressure and water content to reach saturation. A higher dew point indicates more moisture in the air; a dew point greater than 20 °C (68 °F) is considered uncomfortable and greater than 22 °C (72 °F) is considered to be extremely humid. Frost point is the dew point when temperatures are below freezing. Weather

Body Water is the water content of an animal body that is contained in the tissues, the blood, the bones and elsewhere. This water makes up a significant fraction of the human body, both by weight and by volume. Ensuring the right amount of body water is part of fluid balance, an aspect of homeostasis. The average human adult male is approximately 69% water, by weight.

The average human being consists of about 7 x 1027 atoms (7,000 trillion trillion atoms) — 65 percent oxygen, 18 percent carbon, 10 percent hydrogen, 3 percent nitrogen, 1.4 percent calcium, 1.1 percent phosphorous, and traces of 54 other chemical elements. 

Composition of the Human Body (wiki)

Hydrocephalus is an abnormal accumulation of cerebrospinal fluid (CSF) in the brain.

Cerebrospinal Fluid (CSF) is a clear, colorless body fluid found in the brain and spine. It is produced in the choroid plexuses of the ventricles of the brain. It acts as a cushion or buffer for the brain's cortex, providing basic mechanical and immunological protection to the brain inside the skull. The CSF also serves a vital function in cerebral autoregulation of cerebral blood flow.

Body Fluid bodily fluids or biofluids are liquids originating from inside the bodies of living people. They include fluids that are excreted or secreted from the body as well as body water that normally is not. (Drool) The dominating content of body fluids is body water. Approximately 60-65% of body water is contained within the cells (in intracellular fluid) with the other 35-40% of body water contained outside the cells (in extracellular fluid). This fluid component outside the cells includes the fluid between the cells (interstitial fluid), lymph and blood. There are approximately 6 to 10 liters of lymph in the body, compared to 3.5 to 5 liters of blood.

Dehydration (wiki)
Mouth is dry. The darker the urine, the more dehydrated you are. Test the elasticity of your skin by pinching the back of your hand and hold it for a few seconds. Let go and if the little "tent" stays pinched and takes more than 5 seconds to go back to normal, it's usually a sign of moderate dehydration. Sugary drinks cause you to lose more body fluid. Sugary drinks create an acidic environment that can impair enzyme function and decrease your body’s water storage capacity, which is necessary to metabolize all the extra sugar. High-Protein intake causes the body has to use more water to metabolize the naturally occurring nitrogen in protein, and cells can become water-depleted. Salty Foods increase fluid loss in your body because water is needed to eliminate all the extra sodium naturally present in salt. On average, you lose about one liter (approx 34 ounces) of fluid per hour of exercise.

Transepidermal Water Loss is defined as the measurement of the quantity of water that passes from inside a body (animal or plant) through the epidermal layer (skin) to the surrounding atmosphere via diffusion and evaporation processes.

There are about 5 Sextillion Atoms in a drop of water. (that's 21 zeros)

There are more atoms in a glass of water than glasses of water in all the oceans on Earth.

One drop of water has the volume of about 0.05 mL.
Because the density of water is 1, the mass is 0.05 g.
The molar mass of water (H2O) is 18.0 grams/mol (1.008 + 1.008 + 16.0).  
How many molecules in a drop of water?
This means there is one mole of water in 18.0 grams.
One mole is 6.02 × 1023 molecules. (10²³)  Avogadro Constant
Then you can convert grams to number of atoms:
0.05 grams ÷ 18.0 grams × (6.02 × 1023 molecules) = 1.67 × 1021 molecule.

Fluid Dynamics is a subdiscipline of fluid mechanics that deals with fluid flow.

Fluid Mechanics is the branch of physics that studies the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. Fluid mechanics has a wide range of applications, including for mechanical engineering, chemical engineering, geophysics, astrophysics, and biology. Fluid mechanics can be divided into fluid statics, the study of fluids at rest; and fluid dynamics, the study of the effect of forces on fluid motion

Hydrostatics is the branch of fluid mechanics that studies incompressible fluids at rest. It encompasses the study of the conditions under which fluids are at rest in stable equilibrium as opposed to fluid dynamics, the study of fluids in motion. Hydrostatics are categorized as a part of the fluid statics, which is the study of all fluids, incompressible or not, at rest.

Capillary Action sometimes capillarity, capillary motion, or wicking, is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied carbon fiber, or in a cell. It occurs because of intermolecular forces between the liquid and surrounding solid
surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container wall act to lift the liquid.

Superfluidity is a state of matter in which the matter behaves like a fluid with zero viscosity; where it appears to exhibit the ability to self-propel and travel in a way that defies the forces of gravity and surface tension. Superfluidity is found in astrophysics, high-energy physics, and theories of quantum gravity. The phenomenon is related to Bose–Einstein condensation, but neither is a specific type of the other: not all Bose-Einstein condensates can be regarded as superfluids, and not all superfluids are Bose–Einstein condensates.

Viscosity fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of "thickness"; for example, honey has a much higher viscosity than water.

How Much Does One Ml Of Water Weigh At 4 Degrees Celsius?
Pure water has the highest density at the temperature of 3.98 degrees Celsius. The density is then 999.975 kg/m3 or 0.9999750 g/cm3 or 0.9999750 g/mL.
At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml, 1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m
Water was used as the basis for establishing the metric unit of mass, however, so it is easier to remember that a cubic centimeter of it has a mass of 1 gm. Knowing that there are 1000 cubic centi-meters in a liter, you can also use 1
kilogram (1000 grams) per liter for water's mass density.

Properties of Water is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, nearly colorless with a hint of blue. The simplest hydrogen chalcogenide, it is by far the most studied chemical compound and is described as the "universal solvent" for its ability to dissolve many substances. This allows it to be the "solvent of life". It is the only common substance to exist as a solid, liquid, and gas in nature.

The magnetic fluctuations of the tides depend on the electrical conductivity of the water -- and the electrical conductivity of the water depends on its temperature. More than 90 percent of the excess heat in the Earth system goes into the ocean.

Water is the second most abundant substance in the universe. It dissolves more materials than any other solvent. It stores incredible amounts of energy. Life as we know it would not be possible without it. And although it covers more than 70% of the Earth’s surface, many parts of the world are in dire straits for lack of it. Water makes up 75% of our bodies. Every day we drink it, bathe in it, clean with it and use it to dispose of our wastes. Two atoms of hydrogen and one of oxygen. The hydrogen bonds that continually form and reform between its slightly negatively charged oxygen and slightly positively charged hydrogen components. Thanks to these bonds, water molecules attract one another far more strongly than those of almost any other substance. As it cools from its liquid to solid state, actually expands. Virtually every other substance becomes denser as it “freezes,” but thanks to this remarkable property, ice cubes float in our drinks. More importantly for living organisms, lakes and other bodies of water freeze from the top down. The average snow crystal contains about 10 quintillion (10 followed by 18 zeroes) water molecules, it is easy to see why the number of possible combinations is unimaginably large. Water has a cycle of evaporation, condensation, precipitation and runoff back to seas and lakes. The same is true among living organisms, where the hydrogen and oxygen constituents of water are continually combining and recombining through the processes of photosynthesis and respiration. Each time we break down a molecule of glucose, we produce six molecules of water, a reaction that takes place in the typical human body about six septillion (6 followed by 24 zeroes) times per day. Even so, we still don’t produce enough water to meet our own needs. 3% of the Earth’s water is fresh water, the other 97% being found in the oceans. And about 70% of this fresh water is found in glaciers and the ice caps of Antarctica. Earth holds enough water to make a sphere about 860 miles in diameter.

The probability of you drinking a glass of water that contains a molecule of water that also passed through a dinosaur is almost 100%.


Does water take longer to boil at higher altitudes?

A common misconception is that it takes longer to boil water at high altitudes. As explained, it is the exact opposite. Increased elevation = decreased boiling point. Thus this lower boiling point actually takes less time to reach.  High Altitude Cooking
The confusion is created by the fact that because of this lower boiling point, it actually takes longer to cook food in or over water. Because less heat is being transferred through radiation, conduction, and convection, it will take longer to cook a pot of Alpine Pasta at 10,000 feet than at 1,000 feet elevation. Other factors not related to elevation gain, such as colder temperatures and windy conditions, can also increase the time required to cook food over a stove. These factors can be combated using a backpacking stove windscreen. Altitude affects cooking in three different ways: As elevation increases, the boiling point of water decreases – When water boils at lower temperatures, it takes longer for foods to cook in or over water because less heat is being transferred. As water’s boiling point decreases and cooking times increase, the quicker liquid will evaporate – Because water is boiling at a lower temperature, water will begin to evaporate sooner. As elevation increases, air pressure decreases and the faster leavening gases (air, carbon dioxide and water vapor) expand – This mostly only affects baking at high altitudes where the amount of leavening agents should be reduced.

Meteorology is the interdisciplinary scientific study of the atmosphere.
Atmospheric Pressure sometimes also called barometric pressure, is the pressure exerted by the weight of air in the atmosphere of Earth atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point.


Ice

Ice is water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color.
Ice Crystals are solid ice exhibiting atomic ordering on various length scales and include hexagonal columns, hexagonal plates, dendritic crystals, and diamond dust. The highly symmetric shapes are due to depositional growth, namely, direct deposition of water vapour onto the ice crystal
Ice Ih ice-phase-one is the hexagonal crystal form of ordinary ice, or frozen water. Virtually all ice in the biosphere is ice Ih, with the exception only of a small amount of ice Ic that is occasionally present in the upper atmosphere. Ice Ih exhibits many peculiar properties that are relevant to the existence of life and regulation of global climate.
Ice Ic is a metastable cubic crystalline variant of ice.
Ice II is a rhombohedral crystalline form of ice with a highly ordered structure. It is formed from ice Ih by compressing it at temperature of 198 K at 300 MPa or by decompressing ice V. When heated it undergoes transformation to ice III. Ordinary water ice is known as ice Ih.
Ice III is a form of solid matter which consists of tetragonal crystalline ice, formed by cooling water down to 250 K at 300 MPa. It is the least dense of the high-pressure water phases, with a density of 1160 kg/m3 (at 350 MPa). The proton-ordered form of ice III is ice IX.

Spinning ice disk in Michigan's Pine River. An ice disc forms when a section of ice on a partially frozen river breaks off and is pushed in circular rotation by an eddy current, smoothing the ice disc into a perfect circle.

Water Gas is produced from synthesis gas, which is composed of carbon monoxide and hydrogen. Syngas is a useful product but requires careful handling due to its flammability and the risk of carbon monoxide poisoning. The Water gas shift reaction can be used to reduce the carbon monoxide while producing additional hydrogen, resulting in Water Gas.
Water Vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Unlike other forms of water, water vapor is invisible. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation. It is lighter than air and triggers convection currents that can lead to clouds.
Water Cycle

Halo (optical phenomenon) also known as a nimbus, icebow or gloriole) is an optical phenomenon produced by light interacting with ice crystals suspended in the atmosphere, resulting in a wide variety of colored or white rings, arcs and spots in the sky. Many halos are near the Sun or Moon, but others occur elsewhere or even in the opposite part of the sky. Halo types are the circular halo (properly called the 22° halo), light pillars and sun dogs, but there are many more; some of them fairly common, others (extremely) rare.

Stand Like a Mountain, Flow Like Water
“Be like water making its way through cracks. Do not be assertive, but adjust to the object, and you shall find a way around or through it. If nothing within you stays rigid, outward things will disclose themselves. Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot, it becomes the teapot. Now, water can flow or it can crash. Be like water, my friend.”  (Bruce Lee)
