Problem: Steam enters a 75% efficient turbine at a pressure of 800 PSIA and a temperature of 700 degrees and exits at atmospheric pressure.
Key step: The work done by the turbine is generally B2Us, but the specific work is B2PR.
Watch out: So if this is 0.75 if this is less than 100% we expect that the actual change in enthalpy the specific work coming out of the turbine is less than wha...
