Under steady conditions, the rate at which the water leaves the make-up tank is equal to the rate of evaporation plus any small airborne droplets in the air discharge (i.e., drift)

Please calculate the cooling range, approach , and cooling tower efficiency for traial #2 and column 2.

Please compare and comment on the cooling range vs. evaporation rate

1 The difference between the outlet water temperature and the inlet air wet bulb temperature is called a "approach to wet bulb", and the ideal approach should be zero (practically impossible). CoolingTowerEfficiency=(HotWaterTemp.WetBulbTemp.(inlet))(HotWaterTemp.ColdWaterTemp.)100%
