A natural-draft cooling tower is to remove 70 MW of waste heat from the cooling water that enters the tower at 42oC and leaves at 30oC. Atmospheric air enters the tower at 1 atm with dry- and wet-bulb temperatures of 23 and 16oC, respectively, and leaves saturated at 32oC. Determine
(a) The mass flow rate of the cooling water.
(b) The volume flow rate of air into the cooling tower.
(c) The mass flow rate of the required makeup water.
