Answer to Question #164411 in Mechanical Engineering for Rendel De Torres

Question #164411

A reciprocating compressor draws in 14.17 cubic meter per minute of air whose density is 1.26 kg/cu meter and discharges it with a density of 4.86 kg/cu meter at the suction, p1 = 103.42 kPaa; at discharge, p2 = 551.58 kPaa. The increase in the specific internal energy is 78.6188 KJ/kg and the heat transferred from the air by cooling is 30.238 KJ/kg., determine the work on the air in KJ/min. Neglect change in kinetic energy.
