Steam enters a turbine at 3 MPa and 300°C with a velocity of 60 m/s. The inlet to the steam turbine is 3 m higher than the exit. At the outlet of the turbine, the steam is a saturated vapor at 20 kPa with a velocity of 120 m/s. The turbine is well insulated and the mass flow rate through the steady state device is 6 kg/s. a) Calculate the power output generated by the turbine in units of kW. b) Plot State 1 and State 2 on a Tv diagram (you do not need to draw the process). c) Compare the relative magnitudes of the change in enthalpy, change in KE, and change in PE terms in your analysis from part (a). Would it have been a good approximation to neglect changes in KE and PE from the inlet to the outlet for a turbine"?
