1. Determine the irreversibility rate produced by an adiabatic compressor that compresses 0.150 kg/s of refrigerant R-134a from 0.00°C at 0.100 MPa to 80.0°C at 0.500 MPa. The local environmental temperature is 20.0°C.
2. Refrigerant R-22 flows through a condenser at a rate of 2.70 kg/s. It enters the condenser as a superheated vapor at 1.00 MPa and 50.0°C and exits as a saturated liquid at 25.0°C. The average temperature of the condenser is 30°C and the local environmental temperature is 20.0°C. Determine the irreversibility rate for this condenser.
