The difference in elevation between the headwater and tailwater or tailrace.

• Dynamic head

• Net positive suction head

• Gross head

• Effective Head

It conducts the water around the turbine.

• Spiral casing

• Draft tube

• Wicket gate

• Governor

These are movable vertical vanes that are actuated by the governor to control the flow of water and therefore the energy supplied to the runner

• Spillway

• Runner

• Headrace pipe

• Wicket gate

The rotating part of the turbine where the water imparts its energy onto the turbine shaft.

• Runner

• Flywheel

• Impeller

• Lobe

The power output of this plant depends on the water flow in the river; at low river flows the output decreases accordingly.

• Pumped storage plant

• Run-of-river plant

• Storage plant

• all of the above

It provides an efficient and safe means of releasing flow water that exceeds the design capacity of the dam.

• Draft tube

• penstock

• surge chamber

• spillway

This is a grid of screen composed of parallel bars to catch floating debris. It prevent leaves, branches, and other water contaminants from entering the penstock.

• Surge tank

• Trash Rack

• Butterfly valve

• Weir

It is the term used that refers to water in the reservoir

• Headwater

• Discharge

• Tailwater

• Stored water

The speed of a hypothetical model turbine having the same configuration as the actual turbine, when the model would be of the proper size to develop 1 hp at a head of 1 ft

• Synchronous speed

• Specific speed

• Runaway spees

• Turbine speed

The ratio of the effective head to the gross head

• Mechanical Efficiency

• Penstock efficiency

• Hydraulic efficiency

• Volumetric efficiency
