Given: Assume: Find: R-134a enters a well-insulated compressor operating at steady state at a rate of 15 lb/min as a saturated vapor at 20 psi and exits at a pressure of 120 psi. Changes in kinetic and potential energy are negligible. a. The minimum theoretical power input required (hp). b. Temperature at the outlet ("F) assuming that the compression is reversible. C If the actual outlet temperature is found to be 120 °F calculate the isentropic compressor efficiency. d. Draw the actual and isentropic compression processes on a T-s diagram showing the liquid-vapor dome and labeling the states.
