Independent of the flow depths in the open channel flow system, critical flow depth will occur on the humps

If both humps act as a flow control, a hydraulic jump will occur

If no flow control is exerted, the water level will remain constant

The flows across the humps represent rapidly varied flow

Critical flow depth will occur on the humps regardless of the flow rate

In case that the upstream hump acts as a flow control, a hydraulic jump will occur upstream of this hump

If there is no flow control on any of the humps, the water level will remain constant

The flows across the humps represent rapidly varied flow

Independent of the flow depths in the open channel flow system, critical flow depth will occur on the humps

Independent of the flow depths in the open channel flow system, critical flow depth will occur on the humps

If both humps act as a flow control, a hydraulic jump will occur

If no flow control is exerted, the water level will remain constant

The flows across the humps represent rapidly varied flow

Both humps can act simultaneously as a flow control

In case that the upstream hump acts as a flow control, a hydraulic jump will occur upstream of this hump

The open channel flows may not be controlled by any of the two humps

If the flow is not controlled by the humps, the water level will remain constant throughout the open channel flow

Turbulence, aeration and three-dimensional flow motions are common features of hydraulic jumps

A hydraulic jump does not act as a flow control

In open channel flows, hydraulic jumps should be avoided 

A hydraulic jump cannot have an undular free-surface profile

Increasing the flow velocity in a pump will increase the risk of cavitation

For cavitation to occur, the fluid must be at room temperature.

The net positive suction head is an important measure to prevent cavitation.

When water boils cavitation occurs.

Critical flow depth occurs at a flow control

A hump in a channel can act as a flow control

The flow regime upstream of a flow control is subcritical

A sluice gate cannot act as a flow control

A rotadynamic pump can be classified as an axial or centrifugal pump

The pumping mechanism in an axial pump is based upon the lift force

Pump curves do not exist for axial flow pumps

Pump curves are not provided by manufactures

Independent of the flow depths in the open channel flow system, critical flow depth will occur on the humps

If both humps act as a flow control, a hydraulic jump will occur

If no flow control is exerted, the water level will remain constant
