(3). A gas turbine unit consists of a compressor, combustion chamber, turbine and heat exchanger. The 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 0.8 and 0.85 respectively. The air enters the compressor at 15°C at a rate of 17kg/s. the heat exchanger effectiveness is 80%. If the compressor and turbine are connected by a rigid shaft, calculate: (a). the net power (b). the thermal efficiency (c) the thermal efficiency with the heat exchanger bypassed.
