In the case of a Pelton turbine, an additional requirement for its operation at the condition of maximum efficiency is that the ratio of the bucket to initial jet velocity has to be kept at its optimum value of about 0.46.

Pelton turbine --> 0.43 - 0.48.
Francis turbine --> 0.60 - 0.90.
Kaplan turbine --> 1.5 - 2.
