GovHydroPelton

Class Description

Detailed hydro unit - Pelton model. This model can be used to represent the dynamic related to water tunnel and surge chamber. The DetailedHydroModelHydraulicSystem diagram, located under the GovHydroFrancis class, provides a schematic of the hydraulic system of detailed hydro unit models, such as Francis and Pelton.
