A two stage compressor with intercooling between the stages is used to compress air from 1 bar and 15°C to 9 bar in a Gas- Turbine cycle. The high pressure turbine drives the compressor whereas low pressure turbine is coupled with an electrical generator. The compressor and turbine efficiencies are 85%; 75%, respectively. Heat is added to the compressed air after leaving the compressor till its temperature reaches 900°C. The air then expands in HPT to an intermediate pressure and reheat to the 900°C before expanding another time in LPT to 1 bar. Find the intermediate pressure, the turbine work, the back work ratio, and the cycle thermal efficiency. Assume 15 kg/s air

In a steady-state operating power plant, saturated liquid H2O at 122 deg C is fed to a boiler at 3.756 m/s through a pipe (0.03 m diameter). It leaves the boiler at 9 bar and 88.7 m/s. Then, it enters the turbine through a constant 0.13 m diameter pipe. The exit pipe of the turbine is 0.3 m in diameter and T = 310ºC while P = 1.37 bar. If 2.5 kg/s water is fed and there is change in KE, prove that the fluid enters the turbine at 637.06 deg C.

650 kg/min of superheated steam at 13 Mpa, 582 deg. C enters the turbine and initially expands isentropically to the pressure of 9.2 Mpa. After partial expansion, the steam was reheated with the same pressure at 9.2 Mpa and leaves the first reheater at 520 deg. C. It is once again expanded for the second partial expansion to a pressure of 5.4 Mpa where extraction of steam occurs. The remaining steam was reheated to a pressure of 4.9 Mpa and regained a temperature of 470 deg. C after the addition of heat in the second reheater. The final and complete isentropic expansion was executed until it reached an exhaust pressure of 0.04 Mpa. Draw the corresponding schematic diagram and its T-S diagram.
