Problem 12.82

Figure P12.82 shows a compressor followed by an aftercooler. Atmospheric air at 14.7 lbf/in.2 , 908F, and 75% relative humidity enters the compressor with a volumetric flow rate of 100 ft3 /min. The compressor power input is 15 hp. The moist air exiting the compressor at 100 lbf/in.2 , 4008F flows through the aftercooler, where it is cooled at constant pressure, exiting saturated at 1008F. Condensate also exits the aftercooler at 1008F. For steady-state operation and negligible kinetic and potential energy effects, determine (a) the rate of heat transfer from the compressor to its surroundings, in Btu/min. (b) the mass flow rate of the condensate, in lb/min. (c) the rate of heat transfer from the moist air to the refrigerant circulating in the cooling coil, in tons of refrigeration.
