The power output of a steam turbine is 30 MW. Determine the rate of steam flow in the turbine for saturated steam entering at 0.1 MPa. The outlet pressure is 10 kPa and the expansion is reversible and adiabatic.
A turbine accepts superheated steam at 800 psia and 1200°F and rejects it as saturated vapor at 2 psia. Calculate the velocity at the exit and predict the horsepower output of the turbine if the mass flux is 1000 1bm/min.
