**Steam Power Plant and Regenerative Rankine Cycle** A steam power plant operates on an ideal regenerative Rankine cycle. Steam enters the turbine at 6 MPa and 450°C and is condensed in the condenser at 20 kPa. Steam is extracted from the turbine at 0.4 MPa to heat the feedwater in an open feedwater heater. Water leaves the feedwater heater as a saturated liquid. **Task:** Determine the net work output per kilogram of steam flowing through the boiler. Use steam tables. The net work output per kilogram of steam flowing through the boiler is [______] kJ/kg. **Explanation of Components:** - **Turbine:** The entry conditions are 6 MPa and 450°C. Extraction occurs at 0.4 MPa to heat the feedwater. - **Condenser:** Operates at 20 kPa, where the steam is condensed. - **Feedwater Heater:** An open system where extracted steam is used to heat the incoming feedwater, which exits as a saturated liquid. **Objective:** Calculate the specific net work output using thermodynamic principles and steam tables based on the provided cycle conditions.
