Question: Refrigerant-134a enters the condenser of a steady flow Carnot refrigerator as a saturated vapor at 90 psia, and it leaves with a quality of 0.05.

Refrigerant-134a enters the condenser of a steady flow Carnot refrigerator as a saturated vapor at 90 psia, and it leaves with a quality of 0.05. The heat absorption from the refrigerated space takes place at a pressure of 30 psia. Show the cycle on a T-s diagram relative to saturation lines, and determine
(a) The coefficient of performance,
(b) The quality at the beginning of the heat-absorption process, and
(c) The net work input.
