2. In the gas turbine cycle (Brayton cycle) shown; in the first turbine, the gas expands to pressure P5, low enough for this turbine to drive only the compressor. Then, the gas expands through the second turbine (Power turbine) connected to a shaft.
The data is shown in the figure and all processes are assumed to be ideal. a) Determine the intermediate pressure P5, b) The net specific work output of turbine 2 c) The mass flow rate through turbine 2, d)Find the temperature of the air entering the burner (combustion chamber) T3 and e) the thermal efficiency of the turbine 2
