Can you explain how to get the mass balance for water that they have in the solution? An evaporative cooling tower is used by a large power-generating facility. The circulating water enters the tower at 1000 gal/min at 90F. The dry-bulb temperature of the air at the inlet is 70F and the wet-bulb temperature is 50F. The exit temperature of the air is 80F at 80% relative humidity. The cooling tower is designed to cool the water to 70F. The needed rate of makeup water is most nearly Select single answer choice.
