Homework Help: Rankine Cycle Analysis Help

  1. Feb 15, 2015 #1
    1. The problem statement, all variables and given/known data
    The last part of my question reads:

    Give the equations you would use to determine reactor thermal output if the plant is to produce 1000 MWe. All expressions for work and heat transfer rate should be expressed in terms of the appropriate mass flow rate ratios.

    2. Relevant equations
    Efficiency = Wnet/Qh

    3. The attempt at a solution
    I have been given turbine efficiency and pump efficiency. Also, assume I have found the enthalpy at each state point and was subsequently able to determine the net work and heat addition to the system. I feel like I need to determine the mass flow rate by dividing 1000 MWe by Wnet and then plug that value in to the equation for Qh to get thermal output.

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    In general, posting only a part of a question is not a good way to attract users interested in providing help. The OP is in possession of all the facts, yet, for whatever reason, he has only provided a few bits of information with which to work. No one wants to play Twenty (or Forty) Questions; there's other things to do.
