A regenerative vapor cycle has two turbine stages with steam entering the first stage at 12 MPa, 520 C and expanded to 1,200 kPa, where some of the steam is extracted and diverted to the open feedwater heater operating at 1,200 kPa. The remaining steam expands through the second stage to the condenser pressure of 12 kPa. Saturated liquid steam exits the open feedwater heater at 1,200 kPa. For ideal cycle with mass flow rate of steam from the boiler of 35.0 kg/s a) draw the T-S diagram correctly with all points labeled b) show the steam property table & indicate the readings of all relevant properties c) what is the quality of steam at the exhaust of the second stage turbine d) hourly extraction of steam, kg/hr e) work output of the turbine, MW f) cycle thermal efficiency
