Uses Of Water Essay In Tamil

On 20 February 2013, the Indian Government announced the final award.[14] The final award makes an annual allocation of 419 TMC to Tamil Nadu in the entire Cauvery basin, 270 TMC to Karnataka, 30 TMC to Kerala and 7 TMC to Puducherry.[15][16][17] Utilisable water in Tamil Nadu is sum of beneficial water uses and the water going waste to sea in excess of 14 TMC at Lower Coleroon and Grand Anaicuts.

Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions.[1][2] Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure.[3] For those who work in a hot climate, up to 16 litres (4.2 US gal) a day may be required.[1] Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks.[4] Water may also be unacceptable due to levels of toxins or suspended solids.

Point of use water dispensers come with various uses, the best of them cool, heat, and filter water. Point of use water dispensers have more parts than a mounted water dispenser because they usually have more components.

Research on water, air and soil provides scientists with information about these critical natural resources, how they are changing, and what is affecting them. Forest Service Research and Development focuses on the following four focus areas involving water, air and soil:

Sometimes, it is not possible to consume enough fluids because we are too busy, lack the facilities or strength to drink, or are in an area without potable water (while hiking or camping, for example). Additional causes of dehydration include:

Also known as hydroelectric power, this type of green energy uses the flow of water in rivers, streams, dams or elsewhere to produce electricity. Hydropower can even work on a small scale using the flow of water through pipes in the home or can come from evaporation, rainfall or the tides in the oceans.

Most of what has been described above relates primarily to agriculture. However, the principles apply to all land uses. Construction crews and foresters need to protect stream banks and use buffer strips as well. They can avoid major erosion problems and protect soil resources by understanding the natural flow of watercourses, the lay of the land, and the need for organic matter and a diverse environment.

The water for these and other commercial uses comes from the surface and from underground (groundwater) sources. The extent to which a community uses a surface or a groundwater source depends on which source is more abundant in the particular area. For example, the drier central portions of the United States and Canada do not have as much surface water as the eastern and western coasts. In the prairies, wells that reach down to tap underground water sources are more common than in coastal regions such as California.

Some of the water that is used for commercial purposes can be reused. The water used in a car wash is one example. Another example is the water that is applied to golf courses. Surface water that is obtained from a lagoon (shallow body of water cut off from a larger body) can be suitable for keeping agolf course lush and green. Other commercial water uses, such as drinking water, demand water that is free of chemicals and harmful microorganisms.

Metal coagulants or polyelectrolytes do not fully inactivate viruses. Therefore, a potential health hazard exists with the ultimate disposal of water treatment plantsludges. Furthermore, complete virus removal by destabilization with metal coagulants has not been reported. For a safe drinking water, disinfection of the water before distribution is required.

Usheer roots treat the mother earth too. Maybe it is mentioned in Krishi Shastra. Vetiver roots increase the ground water recharge capability of soils. It increases the biomass content in the soil up to 3 meters depth. It will be very difficult to add leaves and manure at that depth. Vetiver roots add the biomass as roots, and they decay after 18 months . Vetiver root oil is termite-repelling. The vetiver root system increases the aeration in the soil, and prevents nematode (small worms that attack the roots and other plants) infection. Because of these effects, vetiver grown as rows along vegetable farms, and around trees in orchard have improved the health and yield of the cultivated crops. Thus growing neem, tulasi and vetiver in farms and around houses is good for the health of the plants and animals in the earth. (Contributed by Mr Vinod Kumar).

Furthermore, most aspects of water allocation are under the purview of State laws. Several States have established institutions for allocating water rights among competing uses and users based on seniority. In periods of reduced water availability, senior water rights holders in those States are first in line for water allocation. Water is delivered fully in order of seniority until allocation limits are reached, and then remaining rights holders receive no deliveries. This may make irrigators with less senior water rights particularly vulnerable during periods of drought. In some areas, States and local water districts have established markets to allow for trading of water rights, which can provide a mechanism to reduce the vulnerability of less senior rights holders.

Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor.Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.Dew PointDew point is the temperature at which condensation happens. (Dew is simply condensed water in the atmosphere.) Air temperatures can reach or fall below the dew point naturally, as they often do at night. Thats why lawns, cars, and houses are often coated with water droplets in the morning.Condensation can also produce water droplets on the outside of soda cans or glasses of cold water. When warm air hits the cold surface, it reaches its dew point and condenses. This leaves droplets of water on the glass or can.When a pocket of air becomes full of water vapor, clouds form. The point at which condensation starts can be easily viewed in cumulus clouds, which have flat bottoms. Those flat bottoms are where vapor begins to condense into water droplets.SaturationClouds are simply masses of water droplets in the atmosphere. Molecules in water vapor are far apart from one another. As more water vapor collects in clouds, they can become saturated with water vapor. Saturated clouds cannot hold any more water vapor. When clouds are saturated with water vapor, the density, or closeness, of the molecules increases. The vapor condenses and becomes rain.Cold air holds less water vapor than warm air. This is why warm climates are often more humid than cold ones: Water vapor remains in the air instead of condensing into rain. Cold climates are more likely to have rain, because water vapor condenses more easily there.
