 Refrigerant-12
enters steadily an adiabatic compressor as a mixture of saturated vapor
and saturated liquid with a quality of 95% at 80 kPa at a rate of 1 m3/min
and exits at 2 MPa. The compressor has an adiabatic efficiency of 75%.
Assuming the surrounding conditions to be 100 kPa, 25oC, determine
(a) the actual power, and (b) the rate of entropy generation, (c) the second-law
efficiency. Neglect KE and PE.
What-If Scenario: (a) How will the answers change if the ambient temperature is assumed to be 15oC? (b) If the refrigerant is R-134a instead? Solution: Step-by-step
instructions as well as the TEST-Code can be found in the Tutorial>Daemons>Open&Steady>Practice
page. An image of the Analysis panel is shown below.
