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 the suction, p1 = 15 psia; at discharge, p2 = 80 psia. The increase in the specific internal energy is 33.8 Btu/lb,m. Determine the work on the air in Btu/min and in hp. Neglect change in kinetic energy.
