A vapor compression refrigeration cycle utilizes R-134a as the working fluid. The refrigerant flow rate is 50 g/s. Vapor at 150 kPa and -10 °C enters the compressor and leaves at 1.2 MPa and 75 °C. The power input to the non-adiabatic compressor is measured and found to be 2.4 kW. The refrigerant enters the expansion valve at 1.15 MPa and 40 °C and leaves the evaporator at 160 kPa and -15 °C. Determine the entropy generation in the compression...
