8-141 Refrigerant-134a enters an adiabatic compressor at 160 kPa superheated by 3°C, and leaves at 1.0 MPa. If the compressor has a second-law efficiency of 80 percent, determine a) the actual work input, b) the isentropic efficiency, and c) the exergy destruction. Take the environment temperature to be 25°C. | |
