One technique for operating a steam turbine in partload power output is to throttle the steam to a lower pressure before it enters the turbine, as shown in Fig. P7.39. The steam line conditions are 2 MPa, 400◦C, and the turbine exhaust pressure is fixed at 10 kPa. Assuming the expansion inside the turbine is reversible and adiabatic, determine the specific turbine work for no throttling and the specific turbine work (part-load) if it is throttled to 500 kPa. Show both processes in a T–s diagram.
