A reciprocating compressor draws in 500 ft/min of air whose density is 0.079 Ibm/t° and discharges it at a density of 0.304 Ibm/t°. The pressure in the suction and discharge are 15 psia and 80 psia, respectively. The increase in the specific internal energy is 33.8 BTUMB and the heat transferred from the air by cooling is 13 BTU/lb. Determine the work in the air, in Hp.

A reciprocating compressor draws in 500 ftImin of air whose density is 0.079 Ibm/t° and
discharges it at a density of 0.304 Ibm/t°. The pressure in the suction and discharge are
15 psia and 80 psia, respectively. The increase in the specific internal energy is 33.8
BTU/b and the heat transferred from the air by cooling is 13 BTU/lb. Determine the work
in the air, in Hp.
