Question:

Steam enters an adiabatic turbine at 2000 psia, 1000°F, with a flow velocity of 300 ft/s through four 1-in.-diameter jets. It leaves at 10 psia with a velocity of 40 ft/s and a quality of 0.90. Determine the output power of the turbine. Calculate the error in the output power if the kinetic energy change is neglected. Should the kinetic energy change be included?
