Content- Turbomachine equations, mechanical power balance in a hydraulic
machines, moment of momentum balance applied to the runner/impeller,
generalized Euler equation.
- Hydraulic characteristic of a reaction turbine, a Pelton turbine and a
pump, losses and efficiencies of a turbomachine, real hydraulic
characteristics.
- Similtude laws, non dimensional coefficients, reduced scale model
testing, scale effects.
