In cooling tower, water is cooled by the process of
Condensation
Fusion
Evaporation
Sublimation
Evaporation
●As air rises inside the tower, it receives the latent heat of vaporization from the water and thus the water is cooled.
●As a rule of thumb, for every 100 F (5.5 0C )of water cooling, 1% total mass of water is lost due to evaporation.
Hence, the correct option is (C).
&Key Points:-
●A cooling tower cools the water, heated by industrial equipment and processes by spraying it onto the fill media, which slows the water flow down and exposes to the best air-water contact.
●The water is exposed to air as it flows throughout the cooling tower. The air is being pulled by a motor-driven electric cooling tower fan.
●When the air and water come together, a small volume of water evaporates, creating an action of cooling. The colder water gets pumped back to the process/equipment that absorbs heat or the condenser. It repeats the loop over and over again to constantly cool down the heated equipment or condensers.
