The energy state of the flow can be expressed using the

Reynolds Number

Froude Number

Bernoulli Number

Manning’s number

Flow transitions from a subcritical flow to supercritical flow will result in a hydraulic jump:

The depths either side of a sudden change in channel geometry can be found through “X” of the “Y”.

“X” – Sequent Depths “Y” – Force balance equations

“X” – Subsequent Depths “Y” – Force balance equations

“X”– Subsequent Depths “Y” – Energy balance equations

“X” – Sequent Depths “Y” – Energy balance equations

When performing an energy analysis we work from the “X” working “Y”.

“X” – upstream point “Y” – downstream

“X” – critical energy point “Y” – outwards

“X” – point of change “Y” – outwards

“X” – downstream point “Y” – upstream

The Critical Depth of flow is expressed by which equation?

Flow transitions from a supercritical flow to subcritical flow will result in a hydraulic jump:>

True

False

The critical energy of a flow is…

The total energy related to the flow at that point of change

Minimum depth hydrostatic flow energy and velocity flow energy

The minimum specific energy of the flow

The specific head of flow is comprised of:

Elevation head, hydrostatic head and velocity head

hydrostatic head and velocity head

Elevation head and velocity head

Velocity head only

The “dominant” energy is ….?

Always the normal energy

Always the critical energy of the flow

The larger energy value when an energy analysis is performed between two points in the channel flow
