Ман Boiler WST WSP2 OFWH Qc WSP1 A power plant operates on a regenerative vapor power cycle with one open feed water heater as shown in the figure. Steam enters the first turbine stage at 10.4 MPa, 550°C and expands to 1.2 MPa, where some of the steam is extracted and diverted to the open feed water heater operating at 1.2 MPa. The remaining steam expands through the second turbine stage to the condenser pressure of 8 kPa. Saturated liquid exits the open feed water heater at 1.2 MPa. Assume the turbine and pumps operate ideally. For the cycle's net power output of 300 MW, determine (a) the thermal efficiency and (b) mass flow rate in kg/s into the first turbine stage. a. Fraction of steam extraction of steam (x) at the first turbine b. The work generated on the turbine stages per kg of water flowing through the boiler c. Total amount of work done on the pumps per kg of water flowing through the boiler d. mass flow rate in kg/s into the boiler. e. Amount of heat absorbed by the working fluid passing through the boiler in kW f. the thermal efficiency the cycle Condenser
