Turbomachinery: number of stages and power of steam turbine

  1. May 24, 2013 #1
    Please help!
    Steam turbine. Given parameters: turbine speed, steam flow, steam inlet and outlet pressures, nozzle and blade velocity coefficients, blade angles and blade velocity. I can find all efficiencies. How could I calculate number of stages required and the actual power produced?

    You would have to do detailed calculations on the internal thermodynamics of the turbine. Essentially, you would be determining the power produced by each stage, and then adding them up to see if you get the output desired. If the calculated output does not match the design output, then the calculations will be repeated, changing the particulars of the stages until the calculated output matches the design figure.
