1) Consider the two-stage, adiabatic steam turbine, shown below. Steam at 15 MPa and 600C enters the high-pressure turbine, which produces 8.4 MW of power. The effluent (exiting flow) from the high-pressure turbine enters the low-pressure turbine at 1 MPa and 250C and leaves at 120 kPa with a quality of 94%. Units f. Ref Phase T P V h Steam P = 15 MPa T = 600C u 5.MP=8.4 MW HI-P Turbine 1 a. Fill in the table of thermodynamic properties you need for this problem. b.
