A reciprocating compressor draws in 500 cubic feet per minute of air whose density is 0.079 ft/cu. ft and discharges it with a density of 0.304 lb/cu. ft. At the suction, P 1 = 15 Psia; at discharge, P 2 = 80 psia. The increase in the specific internal energy is 33.8 BTU/lb and the heat transferred from the air by cooling is 13Btu/lb. Determine the work on the air in BTU/min and in hp. Neglect kinetic energy.

Question
2. A reciprocating compressor draws in 500 cubic feet per minute of air whose density is 0.079
ft/cu. ft and discharges it with a density of 0.304 lb/cu. ft. At the suction, P 1 = 15 Psia; at
discharge, P 2 = 80 psia. The increase in the specific internal energy is 33.8 BTU/lb and the heat
transferred from the air by cooling is 13Btu/lb. Determine the work on the air in BTU/min and in
hp. Neglect kinetic energy.
