Question: The cooling water from the condenser of a power plant enters a wet cooling tower at 40C at a rate of 90 kg/s. The water

The cooling water from the condenser of a power plant enters a wet cooling tower at 40°C at a rate of 90 kg/s. The water is cooled to 25°C in the cooling tower by air that enters the tower at 1 atm, 23°C, and 60 percent relative humidity and leaves saturated at 32°C. Neglecting the power input to the fan, determine
(a) The volume flow rate of air into the cooling tower and
(b) The mass flow rate of the required makeup water.
