2. Areciprocating compressor draws in 500 cubic feet per minute of air whose density is 0.079 Ib/cu.ft and discharges it with a density of 0.304 lb/cu.ft. At the suction, p:= 15 psia; at discharge, p;= 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 Btu/min and in hp. Neglect change in kinetic energy.
