A gas turbine power plant operates on a standard air cycle between extreme pressures of 1 and 6.4 bar. The inlet air temperature is 22°C and the turbine inlet limit temperature is 807°C. The adiabatic efficiencies of the compressor and the turbine are 0.82 and 0.85, respectively. If a regenerator with an efficiency of 0.80 is installed and two ideal stages are used in compression and expansion, determine the thermal efficiency.
Refrigerant 134a enters the compressor of a refrigerator as superheated vapor at 0.20 MPa and -5 ° C at a rate of 0.7 kg / s, and exits at 1.2 MPa and 70 ° C. The refrigerant is cooled in the condenser to 44 ° C and 1.15 ° C. MPa, and throttles at 0.2 MPa. Neglecting any heat transfer and any pressure drop in the connecting lines between the components, show the cycle on a Ts diagram with respect to the saturation lines, and determine (a) the rate of heat removal from the refrigerated space and the inlet power to the compressor, b) the isentropic efficiency of the compressor, c) the COP of the refrigerator, d) show the Ts and Ph diagrams with all points
Air enters the compressor of an ideal gas refrigeration cycle at 12°C and 50 kPa and the turbine at 47°C and 250 kPa. The mass flow rate of air through the cycle is 0.08 kg/s.

A Carnot’s engine is operated between two reservoirs at temperature 450 K and 350 K. If the engine receives 1000 calories of heat from the source in each cycle, calculate the amount of heat rejected to the sink in each cycle.
