A reheat-regenerative Rankine cycle uses steam at 8.4 MPa and 560°C entering the HP turbine. The cycle includes one steam-extraction stage for regenerative feedwater heating, the remainder at this point being reheated to 540°C. The condenser temperature is 35°C. Determine the optimum extraction pressure; fraction of steam extracted, turbine work in kJ.kg; pump work in kJ/kg; and the overall thermal efficiency.
