The power input to a steady$-$flow compressor that uses Refrigerant$-134$a is $10$ kW$.$ The refrigerant enters the compressor at a rate of $0\mathrm{.}3$ kg$/$s in a saturated$-$vapor state at $200$ kPa and leaves at $700$ kPa and $31\mathrm{.}5$C$.$ The surroundings $($ambient air$)$ are at $20$C$.$ Find the followings: a$)$ The volume flow rate of the refrigerant at the compressor inlet, b$)$ The volume flow rate of the refrigerant at the compressor outlet, c$)$ The rate of heat lost from the compressor in kW$,$ d$)$ The rate of entropy change of the surroundings in kW$/$K$,$ e$)$ The rate of entropy change of the refrigerant in kW$/$K$,$ and f$)$ The rate of entropy generated during this compression process. g$)$ Determine the isentropic efficiency of that compressor.
