Superheated steam from the boiler expands in the turbine from inlet pressure p₁ of 50 bar and temperature T₁ of 487 °C to condenser pressure p2 of 18 kPa. In the condenser, the steam condenses to saturated water. The isentropic efficiency of the turbine ns is 78.0 %. The mass flow of steam 9m,h is 140 kg/s. In the boiler, heat flow rate to the circulating fluid (water/steam) is 458 MW. Read from h,s-diagram and calculate: 4. Turbine power Pt MW (with one decimal accuracy) 5.
