Right Answer is: D

SOLUTION

Explanation:

A cooling tower is a special type of heat exchanger in which the warm water and the air are brought in direct contact for ‘evaporative cooling’.

It provides a very good contact of air and water in terms of the contact area and mass transfer coefficient of water vapour while keeping air pressure drop low.

Filling or decking is a process used in cooling towers to increase the wetted surface area of the cooling tower.

The increased wetted surface allows the maximum contact surface area between air and water, thus allows for a higher evaporation rate.
