A regenerative gas turbine power plant is shown in figure. Air enters the compressor at 1 bar, 27°C with a mass flow rate of 0.562

kg/s and is compressed to 4 bar. The isentropic efficiency of the compressor is 80%, and the regenerator effectiveness is 90%. The

pressure drop in the combustion chamber is 0.15 bars as well as in

the regenerator is also 0.15 bars. All the power developed by the

high-pressure turbine is used to run the compressor. The lowpressure

turbine provides the net power output. Each turbine has an isentropic

efficiency of 87% and the temperature at the inlet to the high-pressure

turbine is 1200 K. Draw the T-S diagram and determine the net power

output, in kW, the thermal efficiency and the temperature of the air at

states 2, 3, 5, 6, and 7, in K.​
