A refrigerant, in the vapor phase, behaves as an ideal gas with CP *=6R, and passes into an adiabatic compressor at a rate of 100 mol/min. If the vapor entering the compressor is saturated (q=1) at 270 K, and the compressor efficiency is 0.6 (or 60 %), find the rate at which work, ,, is added to the compressor in kJ/min. The inlet pressure, Pin, is 0.3 bar, and the outlet pressure, Pout, is 0.7 bar.

Thank you so much!
