As Shown In Fig 1 A Steam Turbine At Steady State Is Operated At Part Load By Throttling The Steam To A Lower Pressure 1 (63.49 KiB) Viewed 26 times

As shown in Fig. 1, a steam turbine at steady state is operated at part load by throttling the steam to a lower pressure before it enters the turbine. Before throttling, the pressure and temperature are, respectively, 1.6 MPa and 350°C. After throttling, the pressure is 1 MPa. At the turbine exit, the steam is at 0.10 bar and a quality of 90%. Heat transfer with the surroundings and all kinetic and potential energy effects can be ignored. Determine (a) the temperature at the turbine inlet, in °C. (b) the power developed by the turbine, in kJ/kg of steam flowing (15 marks) Valve em 2 N Power out Turbine P1 = 1.6 MPa T1 = 350°C P2 = 1 MPa 3 P = 0.10 bar X3 = 90% Fig. 1
