Steam is supplied to the first stage of a five-stage pressure-compounded steam turbine at a stagnation pressure of 1.5 MPa and a stagnation temperature of 350°C. The steam leaves the last stage at a stagnation pressure of 7.0 kPa with a corresponding dryness fraction of 0.95. By using a Mollier chart for steam and assuming that the stagnation state point locus is a straight line joining the initial and final states, determine

a. the stagnation conditions between each stage assuming that each stage does the same amount of work;

b. the total-to-total efficiency of each stage;

c. the overall total-to-total efficiency and total-to-static efficiency assuming the steam enters the condenser with a velocity of 200 m/s;

d. the reheat factor based upon stagnation conditions.
