Adiabatic steam turbine - find the second law efficiency

    1. The problem statement, all variables and given/known data

    3. The attempt at a solution
    So pretty much for this question you want to find the actual work output of the turbine and the reversible work output.

    To find the reversible (theoretical) work output, you know that s2 = s1, so based on that information you can find what the quality of the vapor coming out of the steam is and thus find the work output.

    To find the actual work output, the solution suggests that the quality of the vapor coming out of the turbine is x = 1. This suggests that steam is coming out of the turbine. I don't understand why x = 1 for actual work output. Could someone please explain this?

    Thanks

    The quality of saturated vapor is, by definition, 1. Saturated vapor has no moisture present.

    So saturated steam and vapor mean the same thing then?
