Water is to be cooled 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 lbm/h. ft2 and the air flow is 1400 lbm air/h.ft2. The overall mass-transfer coefficient is KGa = 6.90 lb mol/h.ft3.atm. Calculate the tower height needed if air flow of 1400 lbm air/h.ft2 is used.
