A gas turbine unit has a pressure ratio of 6:1 and a maximum cycle temperature of 600°C. The isentropic efficiencies of the compressor and turbine are 82% and 85% respectively. The turbine and compressor are connected by a rigid shaft. Calculate: (a). the power output of a generator driven by the turbine when the air enters the compressor at 15°C at a rate of 15kg/s. The generator efficiency is 95% (b), the cycle thermal efficiency.
