Explain how much water can be cooled in the pounds

Question

The exit air leaves at95^o F and 90^oF wet bulb. Explain how much water can be cooled in the pounds per hour if the water to be cooled is not recycled, enters the tower at 120^o F, and leaves the tower at 90^o F? Suppose you have been requested to redesign a water-cooling tower that has a blower with a capacity of 8.30 X 10⁶ft³/hr of moist air (at 80^o F and a wet-bulb temperature of 65^oF).
