Q1:

Can a cooling tower cool water below the wet bulb temperature of inlet air ?

A yes

B no

C yes ; but height of cooling tower will be prohibitively high.

D yes ; but the air flow rate should be excessively high.

ANS:B - no

A cooling tower operates by evaporative cooling, where water is cooled by the evaporation of a small portion of it into the air. The wet bulb temperature of the inlet air represents the lowest temperature to which the water can be cooled through this process, as it indicates the temperature to which air can be cooled by evaporating water into it. Therefore, the correct answer is: No A cooling tower cannot cool water below the wet bulb temperature of the inlet air.
