Awet cooling tower is to cool 40 kg/s of water from 40 to 30°c. atmospheric air enters the tower at 1 atm with dry- and wet-bulb temperatures of 22 and 16°c, respectively, and leaves at 32°c with a relative humidity of 95 percent. using the psychrometric chart, determine (a) the volume flow rate of air into the cooling tower and (b) the mass flow rate of the required makeup water.
