FRANCIS TURBINE - CONSTANT HEAD

Objective

To conduct the performance test on Francis turbine under constant head and to plot the operating characteristics.

Apparatus used:

Francis Turbine Setup with Centrifugal Pump, Pressure Gauges, Spring Balance with Weights etc.


 Description Francis turbine: is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts.

Cavitation: is a phenomenon which manifests itself in the pitting of the metallic surfaces of turbine parts because of the formation of cavities.

Both ends of the pipe must be trimmed to ensure parallel faces.
