A power plant uses a gas turbine to produce electricity. Assume that the gas-turbine operates on the ideal Brayton cycle has a pressure ratio of 8. The outside air temperature is 27 C and without preheating, the air is drawn into the compressor. The air compressed in the compressor and its pressure and temperature increase.

T B A D Consider the cycle in the diagram (very similar to the Rankine Cycle) using water as the working fluid. Process A-B: A saturated mixture of water is pumped from low pressure to a high pressure saturated liquid in an iso- entropic (and adiabatic) process. Process B-C: The high pressure saturated liquid enters a boiler where it is heated at constant pressure process by an external heat source to a super-heated vapor. Process C-D: The super-heated vapor goes through a turbine, generating power exiting as a saturated vapor. Assume an iso-entropic (and adiabatic) process and neglect kinetic energy and potential energy changes. Process D-A: The saturated vapor then enters a condenser where it is condensed at a constant pressure process back to its original state.
