Refrigerant 134a is compressed at steady state from 2.4 bar, 0oC, to 12 bar, 50oC. Refrigerant enters the compressor with a volumetric flow rate of 0.38 m3/min, and the power input to the compressor is 2.6 kW. Cooling water circulating through a water jacket enclosing the compressor experiences a temperature rise of 4oC from inlet to exit with a negligible change in pressure. Heat transfer from the outside of the water jacket and all kinetic and potential energy effects can be neglected. Determine the mass flow rate of the cooling water, in kg/s.
