Question:
Steam is supplied in a line at 400 lbf/in.2, 1200 F. A turbine with an isentropic efficiency of 85% is connected to the line by a valve, and it exhausts to the atmosphere at 14.7 lbf/in.2. If the steam is throttled down to 300 lbf/in.2 before entering the turbine, find the actual turbine specific work. Find the change in exergy through the valve and the second-law efficiency of the turbine.
