liquid water enters a cooling tower operating at a steady state 40ºC with a mass flow rate of 105 kg/h. Cooled water at 25ºC exits the cooling tower at the same mass flow rate. Makeup water is supplied at 23ºC. Atmospheric air enters the tower at 30ºC, 1 bar, 35% relative humidity. A saturated moist air stream exits at 34 ºC, 1 bar. Determine a. the mass flow rates of the dry air and makeup water, each in kg/h. b. teh rate of exergy destruction within the cooling tower, in kW, for T0 = 23ºC
