Question:

A turbine receives steam at a pressure of 1000 psia and 1000 F and exhausts the steam at 3 psia. The velocity of the steam at the inlet is 50 ft/s. At the outlet, which is 10 ft higher, the velocity is 1000 ft/s. Assuming that the operation is reversible and adiabatic, determine the work produced per unit mass.
