The cooling water from the condenser of a power plant enters a wet cooling tower at 110oF at a rate of 100lbm/s. Water is cooled to 80oF in the cooling tower by air that enters the tower at 1 atm, 76oF, and 60 percent relative humidity and leaves saturated at 95oF. Neglecting the power input to the fan, determine
(a) The volume flow rate of air into the cooling tower.
(b) The mass flow rate of the required makeup water.
