Air enters a compressor at 14.7 psia and 77F and is compressed to 140 psia and 200F.

Question:

Air enters a compressor at 14.7 psia and 77°F and is compressed to 140 psia and 200°F. Determine the minimum work required for this compression, in Btu/lbm, with the same inlet and outlet states. Does the minimum work require an adiabatic compressor?
