A steam turbine, as shown in Figure Q3, operates at steady state with inlet conditions of Pi= 2 MPa, T1 = 480°C and producing 4000 kW. Saturated steam leaves the turbine at a pressure of 0.1 bar where it is condensed at 45.81 °C in the condenser. There is no significant heat transfer between the turbine and the condenser and their surroundings, and kinetic and potential energy changes between inlet and exit are negligible.
