1 Consider A Regenerative Vapor Power Cycle With One Open Feedwater Heater Steam Enters The Turbine At 10 0 Mpa 460 C 1 (46.41 KiB) Viewed 45 times

1. Consider a regenerative vapor power cycle with one open feedwater heater. Steam enters the turbine at 10.0 MPa, 460°C and expands to 0.8 MPa, where some of the steam is extracted and diverted to the open feedwater heater operating at 0.7 MPa. The remaining steam expands through the second stage turbine to the condenser pressure of 0.008 MPa. Saturated liquid exits the open feedwater heater at 0.8 MPa. The isentropic efficiency of each turbine stage is 75% and each pump operated isentropically. If the net power output of the cycle is 200 MW, determine (a) the thermal efficiency and (b) the mass flow rate of steam entering the first turbine stage, in kg/h.
