Air enters a 1-ft-diameter cooling section at 14.7 psia, 90F, and 60 percent relative humidity at 600 ft/min. The air is cooled by passing it over a cooling coil through which cold water flows. The water experiences a temperature rise of 14F. The air leaves the cooling section saturated at 70F. Determine the heat transfer rate, the water's mass flow rate, and the airstream's exit velocity. (
