Pls answer thank you! The following data were obtained during performance test with a simple open cycle gas turbine engine: compressor inlet temperature, 520*R: compressor isentropic discharge temperature, 672"R: actual compressor discharge temperature, 691"R: turbine inlet temperature, 1500 R: turbine isentropic discharge temperature. 1184"R: and turbine actual discharge temperature, 1216°R. For these conditions calculate the thermal efficiency in percent.

A certain refrigerator has a COP of 5.00. When the refrigerator is running, its power input is 500 W. A sample of water of mass 500 g and temperature 20.0°C is placed in the freezer compartment. Assume all other parts of the refrigerator stay at the same temperature and there is no leakage of energy from the exterior, so the operation of the refrigerator results only in energy being extracted from the water. -->Compare the cost to make 44 kg of ice using two different refrigerators; one has a COP of 5.00 and the other has a COP of 6.00. Electricity costs $0.10 per kWh. Using the same assumptions given in the example, find the cost difference (in dollars) between the refrigerators to freeze the water.
