$114$E Refrigerant$-134$a enters the condenser of a steadyflow Carnot refrigerator as a saturated vapor at $90$ psia, and

it leaves with a quality of $0\mathrm{.}05.$ 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
