A closed cycle gas turbine power plant is shown in Figure 1 the working fluid can be modelled as perfect air, which flows around the system at 90 kg/s. The working fluid enters the compressor at 330 K and 0.4 MPa, and leaves at 4.8 MPa where it enters the heat exchanger. It leaves the heat exchanger at 850 K, where it enters the turbine and leaves at 0. 4 MPa. Assuming that the compressor and turbine have an isentropic efficiency of 100% and taking = 1.4 and Cp = 1.005 kJ/kg.K . For the cycle determine. a) Compressor exit temperature a) Turbine exit temperatures b) Compressor specific work c) Turbine specific work d) Heat input e) Thermal efficiency f) Net power output
