In a simple Brayton cycle, the pressure ratio is 8, and temperatures at the entrance of the compressor and turbine are 300 K and 1400 K, respectively. Both compressor and gas turbine have isentropic efficiencies equal to 0.8. For the gas, assume a constant value of cp (specific heat at constant pressure) equal to 1 kJ/kgK and a ratio of specific heat as 1.4. Neglect changes in kinetic and potential energies.
The power required by the compressor in kW/kg of gas flow rate is
304.3
The isentropic outlet temperature is 300×8^(0.4/1.4)=543.43 K. Actual compressor work is cp(T₂s−300)/0.8≈304.3 kJ/kg, or 304.3 kW per kg/s.
