A small power plant uses a wet cooling tower to transfer heat from cooling water to the air. The air enters the cooling tower at 101.325 kPa, 4°C, and a relative humidity of 70%. The air exits as saturated air at 101.325 kPa and 25°C. The cooling water enters the cooling tower at 30°C and exits the cooling tower at 7°C. The mass flow rate of the cooling water is 180 kg/s. Determine the rate at which water must be replaced in the cooling water returning to the process, and the volumetric flow rate of the incoming moist air to the cooling tower.
