Refrigerant 134a is compressed at steady state from 2.4 bar, 0 degrees celcius, to 12 bar, 50 degrees celcius. Refrigerant enters the compressor with a volumetric flow rate of 0.38m^3/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 4 degrees celcius 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. The specific heat for liquid water is 4.179 kJ/kg*K. Determine the mass flow rate of the cooling water, in kg/s. (Hint: two independent subsystems are involved -a compressor with one inlet and one outlet, and a water jacked with one inlet and one outlet. The heat released by the compressor will be completely absorbed by the water jacket.)
