Question: Data for a regenerative vapor power cycle using an open and a closed feedwater heater, similar in design to that shown in the figure below,

Data for a regenerative vapor power cycle using an open and a closed feedwater heater, similar in design to that shown in the figure below, are provided in the table below. Steam enters the turbine at 14MPa,560C, state 1, and expands isentropically in three stages to a condenser pressure of 45 kPa , state 4.
Saturated liquid exiting the condenser at state 5 is pumped isentropically to state 6 and enters the open feedwater heater. Between the first and second turbine stages, some steam is extracted at 1 MPa , state 2, and diverted to the closed feedwater heater. The diverted steam leaves the closed feedwater heater as saturated liquid at 1 MPa , state 10, undergoes a throttling process to 0.2 MPa , state 11, and enters the open feedwater heater.
Steam is also extracted between the second and third turbine stages at 0.2 MPa , state 3, and diverted to the open feedwater heater. Saturated liquid at 0.2 MPa exiting the open feedwater heater at state 7 is pumped isentropically to state 8 and enters the closed feedwater heater. Feedwater exits the closed feedwater heater at 14MPa,170C, state 9, and then enters the steam generator.
