A wet cooling tower is to cool 60 kg/s of water from 40 to 26°C. Atmospheric air enters the tower at 1 atm with dry- and wet-bulb temperatures of 22 and 16°C, respectively, and leaves at 34°C with a relative humidity of 90 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. Answers: (a) 44.9 m3/s, (b) 1.16 kg/s
