GATE 2025 FLUID MECHANICS 24

Assertion (A) : A minor change in specific energy at or close to critical state will cause a major change in depth.

Reason (R) : A critical state of flow is characterized by its Froude number being equal to unity.

It is most appropriate to say that uniform flow in an open-channel occurs when there is a balance between

The given table show the specific energy of flow E at various depths of flow, y

The unit discharge is nearly

If y₁ and y₂ are depths upstream and downstream of a hydraulic jump respectively, the loss of energy due to hydraulic jump is

When a flow profile changes from subcritical to supercritical flow, critical depth act as a control point.

. The water surface profile resulting from flow underneath the gate in figure is

The normal depth in a wide rectangular channel is increased by 10%. The percentage increase in the discharge in the channel is:
