A Rankine cycle with superheat is to be designed using water as the working fluid. The boiler pressure will be 1000 psia and the peak temperature will be 900 °F. (a) Determine the temperature required for the condenser if the expansion through the turbine is isentropic, and the vapor is to be saturated at the outlet of the turbine. (b) Determine the temperature of the condenser if the expansion through the turbine is isentropic, but the vapor leaving the turbine is to have a quality of 94%. (c) Determine the temperature of the condenser if the turbine operates with an adiabatic turbine efficiency of 94%, and the vapor leaving the turbine is to be saturated.
many bridge designs today contain simple geometrical components but are constructed into complex ways to ensure that
water vapor at 3.0 mpa and 300c state 1 is cooled to 200cstate 2 then is isothermically compressed to 2.5mpa state 31.
An irreversible gas-turbine power plant has a compressor with an inlet state of 1 bar and 22°C and an outlet state of 4 bars and 470 K. The turbine has an inlet state of 4 bars and 1200 K and an exhaust state of 1 bar and 900 K. The environment is at..
