Consider the Brayton Cycle for gas-turbine heat engines as shown below. Air is compressed from P,=100kPa, T,=20°C to P2=1400 kPa. The inlet temperature to the turbine is Tz=1100°C. The compressor and turbine are both adiabatic and both have isentropic efficiencies of 80%. in Heat exchanger Wool Compressor Turbine Heat exchanger 9 out Use Cp=1.005...
