Thermodynamics rankine cycle problem

  1. Aug 5, 2016 #1
    1. Steam is the working in an ideal rankine cycle with super heating . Super heated vapor (state 1)
    enters the turbine at a temperature of 440 °C. Saturated vapor(state 2) exits the turbine at a pressure of 3.0 bar.

    2. a) Sketch T-S diagram.
    b)Determine the thermal efficiency of the ideal rankine cycle.

    1....Turbine in
    2... Turbine out
    3... Condenser out
    4... Boiler in

    3. The attempt at a solution

    my question is that how I can find out the pressure of the cycle at state 1?

    What is the relationship between state 1 and state 2 in terms of entropy? Does your steam tables have data for superheated steam? What is the entropy of the steam in state 2?
