A natural-draft cooling tower is to remove 50 MW of waste heat from the cooling water that enters the tower at 42°C and leaves at 27°C. Atmospheric air enters the tower at 1 atm with dry- and wet-bulb temperatures of 23 and 18°C, respectively, and leaves saturated at 37°C. Determine
(a) The mass flow rate of the cooling water,
(b) The volume flow rate of air into the cooling tower, and
(c) The mass flow rate of the required makeup water.
