Uses of Water
Uses of water:
1. For drinking and for life processes.
On an average, a man consumes about 60,000 to 80,000 litres of water in his lifetime. The body of an adult contains nearly 40 to 50 litres of water at any given time and water constitutes about 66% of the average body make up.
Aqueous solutions fill the cells in the body. Nutrients, oxygen, and metabolic waste products are transported by blood, which is mostly water. Digested food is absorbed in the form of an aqueous solution. In plants too nutrients are transported in the form of aqueous solutions.
2. In agriculture
Plants absorb their nutrients from the soil in the form of dilute aqueous solutions. Much of the worlds food crops are now grown under irrigation i.e. where regular water supply is diverted from dams, rivers, lakes etc.
3. In food industry
Water is the common medium used all over the world to prepare various types of foods i.e., for cleaning of food, cooking with/in water: preservation (freezers, fridges etc.) washing and cleaning of utensils, hands etc.
4. In bathing, washing, cleaning, sanitation etc.
5. In industries
Chemical industries are the greatest consumers of water; for instance, 170 litres of water is needed to manufacture just 1 kg of steel and about 144 tons of water is needed to produce one ton of paper.
6. For hydro-electric power production.
7. For transportation as well as recreation.
Transportation by sea and recreation such as swimming, fishing, sailing and other water sports are the important means of using water. 1. For cooking food, for cleaning and drinking. 2. For cultivating food. 3. For transport and recreation. 4. For cleaning. 5. For plants and animals to live in. 6. For factories, industries and power stations
Sources of water:
Sources of fresh water
