A reciprocating compressor draws in 500 cubic feet per minute of air whose density is 0.079 lb/cu ft and discharges it with a density of 0.304 lb/cu ft. At suction, p1= 15 psia; at discharge , p2= 80psia. 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 Btu/min and in hp. Neglect change in kinetic energy
