Question

What is the disadvantage of control measures of thermal pollution by passing the heated water?

(a) Water is lost due to leakage

(b) Water is lost due to absorption

(c) Water is lost due to dilution

(d) Water is lost due to evaporation

The question was asked by my school principal while I was bunking the class.

I'd like to ask this question from Thermal Pollution in division Environmental Pollution of Energy Management

Answer 1

Right choice is (d) Water is lost due to evaporation

To elaborate: Thermal pollution can be controlled by passing the heated water through a large shallow cooling pond into which hot water is pumped and a cooling tower after it leaves the condenser. In both the cases large amounts of water are lost to evaporation.
