Refrigerant-134a at 140 kPa and 210C is compressed by an adiabatic 1.3-kW compressor to an exit state of 700 kPa and 60C. Neglecting the changes in kinetic and potential energies, determine (a) the isentropic efficiency of the compressor, (b) the volume flow rate of the refrigerant at the compressor inlet, in L/min, and (c) the maximum volume flow rate at the inlet conditions that this adiabatic 1.3-kW compressor can handle without violating the second law.

Question
Refrigerant-134a at 140 kPa and 210C is compressed
by an adiabatic 1.3-kW compressor to an exit state
of 700 kPa and 60C. Neglecting the changes in kinetic and
potential energies, determine (a) the isentropic efficiency of
the compressor, (b) the volume flow rate of the refrigerant
at the compressor inlet, in L/min, and (c) the maximum
volume flow rate at the inlet conditions that this adiabatic
1.3-kW compressor can handle without violating the second
law.
