Liquid water enters a cooling tower operating at steady state at 40°C with a mass flow rate of 10s kg/hr Cooled water at 25°C exits the cooling tower at the same mass flow rate. Makeup water is supplied at 23℃ Atmospheric air enters the tower at 30°C, 1 bar, 35% relative humidity. A saturated moist air stream exits at 34°C, 1 bar. Ignoring the effects of KE and PE, determine
a. The mass flow rate of the dry air and makeup water, each in kg/hr
b. The rate of exergy destruction within the cooling tower, in kW, for To 23°C
