In Combined power plant, the gas-turbine cycle has two stages of compression, with an intercooler between the stages. Air enters the first stage at 100 kPa, 22 °C. The pressure ratio across each compressor stage is 4.9, and each stage has an isentropic efficiency of 83%. Air exits the intercooler at 72 °C. The maximum cycle temperature is 1400 °C, and the gas cycle has a single-turbine stage with an isentropic efficiency of 90%. The exhaust is rejected at 232 °C. While the steam power plant operates on the reheat-regenerative Rankine cycle with a closed feed-water heater. A 24 kg/s of steam enters the high-pressure turbine. Assuming that the isentropic efficiency of 80% for the pumps.
