[10 points] Find the thermal efficiency of this ideal Rankine cycle with superheat. b. [5 points] Find the power output from an actual turbine with isentropic efficiency of 92% and flow rate of 0.6 kg/s operating with the same inflow conditions and outflow pressure. c. [5 points] Determine the temperature and enthalpy at the outflow of the actual turbine. (The steam tables needed are found in the equation sheet.) In the blank below, enter the enthalpy that you found in Part c in units of kJ/kg. Give your answer to four significant digits and do not include units in your answer. The answer you give below must match the answer in your hand calculations. Work this problem on a separate sheet of paper. Start with equations from the equation sheet and show all work including the substitution of numbers before solving. After completing the exam, scan your work and upload to the Canvas dropbox.
A heаt pump is used tо heаt а hоuse. When the оutside air temperature is [x]K and the inside is maintained at 293K, the heat loss from the house is [y] kW. a. What is the minimum electric power (kW) required to operate the heat pump? b. What is the rate of heat transfer to the heat pump? c. What is the COP for an ideal heat pump operating between these temperatures? In the blank below, enter your answer to Part c. Give your answer to four significant digits and do not include units in your answer. The answer you give below must match the answer in your hand calculations.
