    Steam at a rate of 15lbm/s enters a turbine at 500 Psia, 800f and exits at 5 Psia. For a reversible, adiabatic process (iseentropic), what is the work out of the turbine in Btu/s and what is the entropy generation?

    Solution Preview

    You need to determine the condition of the input steam. Use the accompanied references.

    At 500 Psia and 800F, the inlet steam is superheated. Thus s1 = 1.6571 Btu/lbm R and h1 =1412.1 Btu/lbm
    Because ...
