A gas-turbine engine operates with 2-stage compression and 2-stage expansion. It receives incoming air at 100 kPa and 25°C before the air passes through a regeneration, reheating and intercooling processes. Across each compressor, the pressure ratio is 3.8, with 300 kJ/kg of heat are received by the air at each combustion chamber. The generator is operating perfectly and increases the cold air temperature by 22°C. Assuming isentropic operations during compression and expansion stages, with constant specific heats at room temperature, evaluate the system's thermal efficiency.

A gas turbine plant of 1000 kW capacities takes the air at 1.11 bar and 15°C. The pressure ratio of the cycle is 6 and maximum temperature is limited to 715°C. A regenerator of 65% effectiveness is added in the plant to increase the overall efficiency of the plant. the pressure drop in the combustion chamber is 0.12 bars as well as in the regenerator is also 0.12 bars. Assuming the isentropic efficiency of the compressor 75% and of the turbine is 75%, determine the plant thermal efficiency. Neglect the mass of the fuel.
