The cooling water from the condenser of a power plant enters a wet cooling tower at 45oC at a rate of 40 kg/s. The water is cooled to 22oC in the cooling tower by air which enters the tower at 1 atm, 20oC, 60% relative humidity and leaves saturated at 30oC. Neglecting the power input to the fan, determine (a) the volume flow rate of the air into the cooling tower and (b) the mass flow rate of the required makeup water. (c) What-if Scenario: What would the mass flow rate in (b) be if mass flow rate of water were 60 kg/s instead of 40 kg/s?
