This is problem 7-5 from El-Wakil’s Powerplant Technology book-- an included-draft cooling tower cools 90,000 gallons per minuteof water from 84 to 68 degFahrenheit. Air at 29.75 inHg absolutepressure, 70 degFahrenheit dry bulb and 60 degFahrenheit wet bulb,enters the tower and leaves saturated at 80 degFahrenheit. Find (a)the volume flow rate of air, in cubic feet per minute, and (b) themakeup water required, in pound mass per hour.
