Steam flows into turbine. The inlet conditions are inlet (p=2 MPa, t=350 C) exit (p=0.1MPa, quality 100%).

I don't understand how they got the h values of hinlet =3137 kJ/kg.

Do you use the steam or superheated steam table?

Enthalpy entering turbine is superheated steam @ 2 mpa 350 C refer at steam tables

h = 3137 kj/kg

s = 6.9563 kj/kg-k

I still don't understand, could you please explain a little more?

The superheated table only goes up to 1MPa. And how are you getting s=6.9563kJ/kg-k?
