Steam flows through a small steam turbine at the rate of 10,000 kg/hr, entering at 600 C and 2 MPa and emerging at 0.01 MPa with 4% moisture. The flow enters at 50 m/s at a point 2 m above the discharge and leaves at 80 m/s. Compute the shaft-power output [MW], assuming that the device is adiabatic but considering kinetic and potential energies. How much error would be made were these secondary terms were neglected? Show the process on a P-v state diagram.
