Problem #: $(24$ Points$)11.$

An ideal steam power plant is designed to operate on the combined reheat and regenerative cycle and to produce af fret power output of $10$ MW Steam enters the high$-$pressure turbine at $8$MPa,$550C,$ and is expanded to $0\mathrm{.}6$ MPa $,$ at which pressure some of the steam is fed to an open feed water heater, and the remainder is reheated to $550C$ and the reheated steam is then expanded in the low$-$pressure turbine to $10$ kPa $.$
