Refrigerant-134a at 140 kPa and 10°C is compressed by an adiabatic 0.7-kW compressor to an exit state of 700 kPa and 50°C. 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 0.7-kW compressor can handle without violating the second law.
