Problem $1\mathrm{.}9$:

Steam is supplied to the first stage of a five$-$stage pressure$-$compounded

steam turbine at a stagnation pressure of $1\mathrm{.}5$ MPa and a stagnation

temperature of $350C.$ The steam leaves the last stage at a stagnation

pressure of $7\mathrm{.}0$ kPa with a corresponding dryness fraction of $0\mathrm{.}95.$

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 $200\frac{m}{s}$;

d$.$ the reheat factor based upon stagnation conditions.
