Answer:

Explanation:
The turbine at steady-state is modelled after the First Law of Thermodynamics:

The specific enthalpies at inlet and outlet are, respectively:
Inlet (Superheated Steam)

Outlet (Liquid-Vapor Mixture)

The power produced by the turbine is:



Answer:
Concentration factor will be 1.2
So option (C) will be correct answer
Explanation:
We have given outer diameter D = 1.25 in
And inner diameter d = 1 in and fillet ratio r = 0.2 in
So
ratio will be 
And
ratio will be 
Now from the graph in shaft vs torsion the value of concentration factor will be 1.2
So concentration factor will be 1.2
So option (C) will be correct answer.
