Problem $5$

R$-134$a enters the compressor of a refrigerator at $0\mathrm{.}14$ MPa and $-10C$ at a rate of $0\mathrm{.}05k\frac{g}{s}$ and leaves at $0\mathrm{.}8$ MPa and $50C.$ The refrigerant is cooled in the condenser to $26C$ and $0\mathrm{.}72$ MPa and is throttled to $0\mathrm{.}15$ MPa $.$ Disregarding any heat transfer and pressure drops in the connecting lines between the components, a$)$ sketch the P$-$h diagram of this refrigerator operations, b$)$ the volumetric flow rate at compressor suction, and c$)$ the compressor piston displacement if the volumetric efficiency at this operating condtion is $70\%$
