Liquid water enters a cooling tower operating at steady state at 39°C with a mass flow rate of 105 kg/h. Cooled water at 25°C exits the cooling tower at the same mass flow rate. Makeup water is supplied at 23°C. Atmospheric air enters the tower at 30°C, 1 bar, 35% relative humidity. A saturated moist air stream exits at 34°C, 1 bar. Determine: (a) the mass flow rates of the dry air and makeup water, each in kg/h. (b) the rate of exergy destruction within the cooling tower, in kW, for To 23°C.
