Find the change in exergy through the valve

Reference no: EM131249885

Steam is supplied in a line at 3 MPa, 700?C. A turbine with an isentropic efficiency of 85% is connected to the line by a valve, and it exhausts to the atmosphere at 100 kPa. If the steam is throttled down to 2 MPa 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.
