Question

Refrigerant 134a enters a water-jacketed compressor operating at steady state at -10°C, 1.4 bar, with a mass flow rate of 22.2 kg/s, and exits at 50°C, 12 bar. The compressor power required is 792.9 kW.


Neglecting kinetic and potential energy effects, determine the magnitude of the rate of heat transfer to the cooling water circulating through the water jacket.
