A Steam Power Plant uses an ideal simple Rankine cycle (the process in the pump and turbine is isentropic). Super-hot steam coming out of the boiler which will enter the turbine is at a pressure of 15 bar and a temperature of 450°C and exits the turbine at a pressure of 50 kPa. a. Draw a cycle process diagram (T-s and h-s diagram) b. Determine the enthalpy value at each state/condition level and the steam fraction when it leaves the turbine. c. Calculate the pump work and the work produced by the turbine and the thermal efficiency of the cycle!
