Question 1: A gas turbine unit takes in air at 25 °C and 1.01 bar and the pressure ratio is 9/1. The compressor is driven by the HP turbine and the LP turbine drives a separate power shaft. The isentropic efficiencies of the compressor, and turbine are .89, and .90, respectively. Calculate the power output of an electric generator geared to the turbine when the mass flow rate is 15kg/s. The maximum cycle temp is 700°C (973 kelvin). For the compression process take Cp=1.005kj/kgK and r=1.4; for the combustion process and for the expansion process take Cp 1.11kj/Kg and r=1.33. 20 points
