A gas turbine unit has compressor inlet conditions of 100 kPa and 310 K. The compressor discharge pressure is 700 kPa, and the temperature is 565 K. Fuel enters the combustion chamber and raises the air temperature to 1200 K. The turbine discharge temperature is 710 K, and the pressure is 100 kPa. Determine a ) the compressor and turbine adiabatic efficiencies; b) the cycle thermal efficiency
