Problem $08\mathrm{.}083-$ Isentropic efficiency, volume rate of the compressor.

Refrigerant$-134$a at $140$ kPa and $\backslash (-10^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ is compressed by an adiabatic $\backslash (2\mathrm{.}500-\backslash$mathrm$\{$kW$\}\backslash )$ compressor to an exit state of $700$ kPa and $\backslash (60^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$ Neglect the changes in kinetic and potential energies. Use data from tables.

Problem $08\mathrm{.}083.$a $-$ Isentropic efficiency of a compressor

Determine the isentropic efficiency of the compressor.

The isentropic efficiency of the compressor is Problem $08\mathrm{.}083.$b $-$ Volume flow rate of the compressor with R$134$a

Determine the volume flow rate of the refrigerant at the compressor inlet in $\backslash (\backslash$mathrm$\{$L$\}/\backslash$mathrm$\{$min$\}\backslash ).$

The volume flow rate of the refrigerant at the compressor inlet is

L$/$min$.$ Problem $08\mathrm{.}083.$c $-$ Volume flow rate of the isentropic process

Determine the maximum volume flow rate at the inlet conditions that this adiabatic $\backslash (2\mathrm{.}500-\backslash$mathrm$\{$kW$\}\backslash )$ compressor can handle without violating the second law.

The maximum volume flow rate is

L$/$min$.$
