5. A reciprocating compressor draws in 500 cubic feet per minute of air whose density is 0.079 lb/ft^3 and discharge it with density of 0.304 lb/ft^3 . At the suction P1=15 psia; at discharge, P2=80 psia. The increase in the specific internal energy is 33.8 BTU/lb and the heat transferred from the air by cooling is 13 BTU/lb. Determine the work on the air in hp. Neglect change in kinetic energy.
