NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The gas-turbine portion of a combined gas-steam power plant has a pressure ratio of 16. Air enters the compressor at 300 K at a rate of 12 kg/s and is heated to 1500 K in the combustion chamber. The combustion gases leaving the gas turbine are used to heat the steam to 400°C at 10 MPa in a heat exchanger. The combustion gases leave the heat exchanger at 420 K. The steam leaving the turbine is condensed at 15 kPa. Assume all the compression and expansion processes to be isentropic. For air, assume constant specific heats at room temperature.

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
The gas-turbine portion of a combined gas-steam power plant has a pressure ratio of 16. Air enters the compressor at
300 K at a rate of 12 kg/s and is heated to 1500 K in the combustion chamber. The combustion gases leaving the gas
turbine are used to heat the steam to 400°C at 10 MPa in a heat exchanger. The combustion gases leave the heat
exchanger at 420 K. The steam leaving the turbine is condensed at 15 kPa. Assume all the compression and expansion
processes to be isentropic. For air, assume constant specific heats at room temperature.
