Steam flows through a small steam turbine at the rate of 10,000 kg/h, entering at 600oC and 2.0 MPa and emerging at 0.01 MPa with 4 percent moisture (i.e., x = 0.96). 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 and isentropic efficiency, assuming that the device is adiabatic but considering kinetic and potential energies. How much error would be made were these secondary terms neglected? What are the diameters of the inlet and discharge pipes?
