A gas turbine system operates on a simple Brayton cycle. The compressor's efficiency is 0.95 while the efficiency of the turbine is 0.9. Inlet air to the compressor is at 27 degrees of Celsius and 100 kPa. The mass flow rate of air through the compressor is 1 kg/s and the calorific value (energy value) of the fuel is 2000 J/kg. Plot the variation of ideal cycle thermal efficiency and the actual thermal cycle efficiency with pressure ratio.
