Answer to Question #242833 in Physics for John

Question

A reciprocating compressor draws in 500 ft₃/min of air whose density is 0.079lbm/ft₃ and discharges it with density of 0.304lbm/ft₃. At the suction, р₁ = 15 psia, at the discharge, р₂ = 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.
