Refrigerant-134a enters an adiabatic compressor as saturated vapor at 120 kPa at a rate of 1 m3/min

Question:

Refrigerant-134a enters an adiabatic compressor as saturated vapor at 120 kPa at a rate of 1 m3/min and exits at 1 MPa. The compressor has an adiabatic efficiency of 85%. Assuming the surrounding conditions to be 100 kPa and 25oC. Determine
(a) The actual power (Wrev) and
(b) The second-law efficiency of the compressor.
(c) What-if Scenario: What would the actual power be if the compressor had an adiabatic efficiency of 70%?
