Are known for all extractions and inlet of turbine the properties the steam.

if you have the heat balance diagram (@ 25, 50, 75 and full-load) of the turbine, it is possible to calculate the turbine internal efficiency. otherwise it is a little difficult and an appropriate set of experimental data is required,

an example is attached. it should be available in the turbine documents.
