Liquid water at 120F and a volumetric flow rate of 275 3/min enters a cooling tower operang at steady state. Cooled water exits the cooling tower at 90F. Atmospheric air enters the tower at 86F, 1 atm, 35% relave humidity, and saturated moist air at 100F, 1 atm exits the cooling tower. Determine a) the mass flow rates of the dry air and the cooled water, each in lb/min. b) the rate of exergy destrucon within the cooling tower, in Btu/s, for T0 = 77F. Ignore kinec and potenal energy effects
