The compressor used in a refrigeration cycle takes in saturated R-134a vapor at a pressure of 360 kPa and raises it to a pressure of 1.0 MPa. The compressor can be considered well-insulated and inlet and exit velocities are small. In steady-state operation, the mass flow is 0.048 kg/sec and the power requirement is 1450 Watts.

4. Steam enters the condenser of a steam power plant at 20000 kPa and a quality of 95 percent with a mass flow rate of 20 Mg/h. It is to be cooled by water from a nearby river in circulating the water through the tubes within the condenser. To prevent thermal pollution, the river water is not allowed to experience a temperature rise above 10°C. If the steam is to leave the condenser as saturated liquid at 20000 Pa, determine the mass flow rate of the cooling water required.
