Question:

A steam turbine receives water at 2000 lbf/in.2, 1200 F at a rate of 200 lbm/s as shown in Fig P6.78 In the middle section 40 lbm/s is withdrawn at 300 lbf/in.2, 650 F and the rest exits the turbine at 10 lbf/in.2, 95% quality. Assuming no heat transfer and no changes in kinetic energy, find the total turbine work?
