A wet cooling tower is to cool 60 kg/s of water from 40 to 33oC. Atmospheric air enters the tower at 1 atm with dryand wet-bulb temperatures of 22 and 16oC, respectively, and leaves at 30oC 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.
