The compined cycle plant shown in figure uses a gas turbine engine operating with 250 kg/s of air entering at 300K and pressure ratio of 12.5. Use an idea air-starndard cycle as a model of this engine and assume the turbine inlet temperature is 1400K. The steam cycle operates in a simple rankine cycle between 10MPa and 70kPa.

Hello, I need help with the following thermodynamics problem.Thank you!

The compined cycle plant shown in figure uses a gas turbine engine operating with 250 kg/s of air entering at 300K and pressure ratio of 12.5.
Use an idea air-starndard cycle as a model of this engine and assume the turbine inlet temperature is 1400K. The steam cycle operates in a simple rankine cycle between 10MPa and 70kPa.

steam is never greater than the local temperature of the gas in the heat
gexchanger.

D.
What is the thermal efficiency for the combined cycle? Compare this to the
thermal efficiency for the gas-turbine cycle alone.
