2019 Q50

A gas turbine with air as the working fluid has an isentropic efficiency of 0.70 when operating at a pressure ratio of 3. Now, the pressure ratio of the turbine is increased to 5, while maintaining the same inlet conditi...

2018 Q34

The pressure ratio across a gas turbine (for air, specific heat at constant pressure, $C_p = 1040$ J/kg. K and ratio of specific heats, $\gamma = 1.4$) is 10. If the inlet temperature to the turbine is 1200 K and the ise...
