The flow through nozzles is deemed as adiabatic i.e. isentropic, because heat doesn't find time to loss in space due to very high speed of fluid, but practically there should be some heat losses, isentropic heat drop represent our assumption i.e (s=constant) & heat drop represent the very actual case,

Is there any significance of internal efficiency in turbines?
Only stage efficiency and overall efficiency are calculated.
