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.
