Steam enters a turbine with a pressure and temperature of 12.5 MPa and 700 oC and leaves at 50 kPa as a saturated vapor. the flow area at the turbine inlet is 50 cm^2 and at the exit it is 350 cm^2. the steam flows steadily through the turbine at a mass flow rate of 25 kg/s.
- calculate the velocities (m/s) of the steam at the inlet and outlet
- determine the power (kW) that can be produced by the steam assume negligible heat transfer.
