Refrigerant R-134a is compressed steadily and adiabatically in a reversible compressor. The volume flow rate entering the compressor is 800 ft3/min. The R-134a enters the compressor at 120 psia, 100 °F and leaves with its pressure being twice the inlet value. Neglect kinetic energy changes, and calculate the power required to operate the compressor.
