(Solved): An ideal Rankine cycle with reheat and a closed feedwater heater with throttled reheat line exhaust ...

An ideal Rankine cycle with reheat and a closed feedwater heater with throttled reheat line exhaust to the condenser. The steam enters the turbine at 138 bar and 538 ?C, expanding to a pressure of 14 bar, reheating to 538 ?C; both reheat and extraction are at 14 bar. The superheated steam expands to a pressure of 0.068 bar. Assume that the feedwater leaving the closed heater is at the temperature of the condensate draw stream. The cycle produces a power of 50 MW.
1. Draw the T-s diagram of the cycle.
2. Calculate the fractions of steam extracted from the turbine.
3. Calculate the flow of steam that must circulate through the boiler [kg/s].
4. Calculate the performance of the cycle.
