ne cycle adds and removes heat and removes work from a"working fluid" (usually steam) to convert work. The working fluid goes through a "cycle", meaning that it starts and ends at the same thermodynam conditions (T, P, etc.) after passing through each step in the process. Each step is typically at steady state. It is heat namic nvenient to label the streams in the way that we used in class: (I) saturated liquid at high pressure Pu (2) saturated vapor...

Water is the working fluid in an ideal regenerative Rankine cycle with one closed feedwater heater. Superheated vapor enters the turbine at 12 MPa, 480°C, and the condenser pressure is 6 kPa. Steam expands through the first-stage turbine where some is extracted and diverted to a closed feedwater heater at 0.7 MPa. Condensate drains from the feedwater heater as saturated liquid at 0.7 MPa and is trapped into the condenser. The feedwater leaves the heater at 10 MPa and a...

Water is the working fluid in a modified Rankine cycle with superheat and reheat. Water as superheated vapor enters the high-pressure stage turbine at 60 bar and 440 C and leaves at 5 bar as liquid-vapor mixture with a quality of xa-0.98. It is then reheated to 400 °C at the same pressure of 5 bar before entering the second stage turbine where it expands to a pressure of 0.1 bar and a mixture quality of x0.96. The condenser pressure...

1. (20 points) Consider a cogeneration system operating at steady state. Superheated steam enters the first turbine stage at 6 MPa, 540 °C. Between the first and second stages, 45% of the steam is extracted at 500 kPa and diverted to a process heating load of 5 x 108 kl/h. Condensate exits the process heat exchanger at 450 kPa with specific enthalpy of 589.13 kl/kg and is mixed with liquid exiting the lower pressure pump at 450 kPa. The entire...
