10.5-2. Minimum Gas Rate and Height of Water-Cooling Tower. It is planned to cool water from 110°F to 85°F in a packed countercurrent water-cooling tower using entering air at 85°F with a wet bulb temperature of 75°F. The water flow is 2000 lbh ft² and the air flow is 1400 lb air/h ft². The overall mass-transfer coefficient is KG a = 6.90 lb mol/h ſt³· atm. . (a) Calculate the minimum air rate that can be used. (b) Calculate the tower height needed if the air flow of 1400 lbm air/h - ft² is used.
