The gas-turbine engine has the following operational parameters: Inlet Air Temperature:537 R Inlet Air Pressure:14.696 psia Compressor Pressure Ratio (rp):6.0 Firing Temperature:2400 R Heat Recovery Steam Generator: Assume that the exhaust from the gas turbine engine is directed to a heat recovery steam generator (HRSG)to produce wet steam (i.e. saturated vapor) at a pressure of 600 psia. Liquid water is supplied to the HRSG at 100F and 600 psia. The exhaust gas from the gas-turbine engine leaves the HRSG at the saturation temperature of the wet steam.
