Pressure A Rankine cycle has a maximum temperature and pressure of 400C and 5 MPa. After the turbine, the pressure is at 200 kPa, with a quality of 0.95. The condenser cools the water to 60C, and the pump restores the pressure to maximum. a) Sketch the cycle on the p-h diagram. Label each process with its component. b) Estimate the enthalpy of each state using the p-h diagram. c) Find the enthalpies of all four states using either steam tables or CoolProp. Indicate how you found the result for full credit. d) Determine the amount of work extracted by the turbine and the amount of heat transfer into the boiler. e) Find the efficiency of the Rankine cycle. Neglect the work in the pump. 50 MPa 20 MPa 10 MPa 5 MPa 2 MPa 1 MPa 500 kPa 200 kPa 100 kPa 50 kPa 20 kPa 10 kPa 5 kPa 1440C 100C 60C 30C 500C 600C 400C 300 200C 2 kPa 1 kPa 0 x-0.1 8-02 FOX 50x 90x BOX =0.9 10C 1000 1500 2000 2500 3000 3500 4000 500 Enthalpy [kJ/kg] Est.h [kJ/kg] Actual h [kJ/kg] State 1 2 3 4
