Water at a flow rate of 40 kg/s should be cooled from 40°C to 30°C in a humid cooling tower. Atmospheric air used in the cooling tower enters the cooling tower at 1 atmosphere pressure, 22°C dry bulb, 16°C wet bulb temperatures and 32°C temperature, 95% relative humidity. Calculate (a) the volumetric flow rate of the air at the entrance to the tower, (b) the mass flow rate of the conservation behaviors required for cooling, using the psychometric diagram.
