Question

which is true about transition from subcritical to supercritical

A. the velocity head is reduced

B. A hydraulic jump is formed

C. the depth of flow is greater than the critical depth

D. the depth of flow is less than the critical depth

E. the froude number is equal to 1

Answer 1

which is true about the transition from subcritical to supercritical

A. the velocity head is reduced - Reduce in the velocity head Increases the velocity and making it supercritical flow.

B. A hydraulic jump is formed - it is formed during the transition of supercritical to subcritical flow.

C. the depth of flow is greater than the critical depth - It is a subcritical flow.

D. the depth of flow is less than the critical depth - It is supercritical flow.

E. the Froude number is equal to 1 - Transition happens when the Froude number is greater or less than 1.

Option - A
