This is problem 7-6 from El-Wakil’s Powerplant Technology book -- a wet cooling tower receives 1.5x106 lbm/min of condenser water at 96 degFahrenheit, and 1.25x106 lbm/min of air at 1 standard atmosphere, 62 degFahrenheit, and 50 percent relative humidity. The air leaves saturated at 82 degFahrenheit. Calculate (a) the exit water temperature, in degrees Fahrenheit, and (b) the percent condenser cooling water makeup due to evaporation.
