Steam enters a compressor operating at steady state at 250 degrees farenheit, 14.7 lbf/in^2 and exits at 400 degrees farenheit and 160 lbf/in^2. The work input is claimed to be 120 Btu per lb of steam flowing through the compressor. Heat transfer between the compressor and its surroundings occurs at an average outer surface temperature of 70 degrees farenheit. Neglecting the kinetic and potential energy changes between inlet and exit, is it possible that the compressor operates as claimed?
