Refrigerant 134a is the working fluid in a vapor-compression heat pump that provides 35 kW to heat a dwelling on a day when the outside temperature is below freezing. Saturated vapor enters the compressor at 2.1 bar, and saturated liquid exits the condenser, which operates at 8 bar.

Determine for an isentropic compressor efficiency of 75%:

(a) the refrigerant mass flow rate, in kg/s.

(b) the magnitude of the compressor power, in kW.

(c) the coefficient of performance.
