A refrigerant 134a at 140 KPa and -10 degree celcius is compressed by an adiabatic 16KW compressor to an exit state of 700KPa and 60 degrees celcius. determine:
a, the mass flow rate of the refigerant entering the compessor (kg/s)
b, the change in entropy of the refrigerant
c, the isentropic efficiency of the compressor
d, calculate the maximum mass flow rate at the inlet condition that this compressor can handle without violating the second law of thermodynamics.
