2.4.1   Efficiency of stage

 

The efficiency of a turbine stage will always be somewhat less than ideal because of the losses discussed in Section 2.2 of this chapter. The efficiency of a well designed stage in a modern HP turbine is about 85-90%.

This stage efficiency is obtained in the following way:

This can be more clearly envisaged through the use of a turbine condition line.
