Brayton cyde with an air-powered regenerator is 8. The highest and lowest temperatures of the cycle are 310 K and 1150 K respectively. The adiabatic efficiencies of the compressor and turbine are 75% and 82%, respectively, and the efficiency of the regenerator is 65%. The temperature of the heat source is 1260 K, and the temperature of the thermal energy storage to which heat is given is 310 K. P output - Po=100 kPa. Using constant specific heats at room temperature; a) Show the cycle on the Ts diagram, b) The temperature of the air at the turbine exit, c) The net work of the cycle, d) Thermal efficiency of the cycle, e) Calculate the usability of the end gases coming out of the regenerator.
