A vapor-compression refrigeration system operates on the cycle shown below. The refrigerant is tetrafluoroethane. For the following set of operating conditions, determine the circulation rate of the refrigerant, the heat-transfer rate in the condenser, the power requirement, the coefficient of performance of the cycle, and the coefficient of performance of a Carnot refrigeration cycle operating between the same temperature levels. Use the table containing the properties of saturated 1,1,1,2-tetrafluoroethane (R134A) and the PH diagram for tetrafluoroethane (HFC-134a).

Water is the working fluid in a vapor power plant. Steam enters the turbine at 4 MPa, 540 °C, and exits the turbine as a two-phase, liquid vapor mixture at 27 °C. The condensate exits the condenser at 25 °C. The turbine efficiency is 90% and the pump efficiency is 80%. The power developed is 1 MW. ▾ ▼ Part A Determine the steam quality at the turbine exit.

Required information Refrigerant-134a enters the condenser of a steady-flow Carnot refrigerator as a saturated vapor at 65.0 psia, and it leaves with a quality of 0.05. The heat absorption from the refrigerated space takes place at a pressure of 30 psia. Determine the coefficient of performance. (Round the final answer to three decimal places.) The coefficient of performance is
