Q3 A forced-draft counter-current water-cooling tower to cool water from 43.3 to 26.7 Celsius. The air enters the bottom of the tower at 23.9 Celsius with a wet bulb temperature of 21.1 Celsius. The value of the HG for the flow conditions is HG=0.533 m. The heat-transfer resistance in the liquid phase will be neglected; that is, hL is very large. Hence, values of the HY * should be used. Calculate the tower height needed if 1.5 times the minimum air rate is used.
