Test: Hydraulic Jump - Civil Engineering (CE) MCQ

Hydraulic pump is a phenomenon in science that deals with hydraulics. It is observed in an open channel flow. Some of the examples of open channel flows are rivers and spillways.

Hydraulic jump is not possible when the initial speed is less than the critical speed. There is a transition that is created during the change. The transition appears as an undulating wave. With the increase in the initial flow, the transition becomes abrupt.

When the hydraulic jump is dynamic or in a moving form it is called as positive surge. Hydraulic jump can be stationery or dynamic. Hydraulic jump can be described using the same analytical approaches.

Hydraulic jump is not possible when the initial speed is less than the critical speed. There is a transition that is created during the change. The transition appears as an undulating wave. Fluid height before the hydraulic jump is low.

Hydraulic jump is not possible when the initial speed is less than the critical speed. There is a transition that is created during the change. Fluid flow before the hydraulic jump is typically smooth turbulent flow.

Hydraulic pump is a phenomenon in science that deals with hydraulics. It is observed in an open channel flow. It depends on the initial speed of the fluid. Thus, option Initial fluid speed is the correct answer.

Open channel flow is a flow that deals with hydraulics in fluid mechanics. It is a type of liquid flow that flows through a free surface. This free surface is called as a channel. And since the channel is free, it is called as an open channel flow.

Fluid speed before the hydraulic jump is supercritical. It is said to be supercritical because it is faster than the wave speed. It is also called as shooting speed or superundal.

Hydraulic jump is not possible when the initial speed is less than the critical speed. There is a transition that is created during the change. The transition appears as an undulating wave. Fluid height after the hydraulic jump is high.

Hydraulic jump is not possible when the initial speed is less than the critical speed. There is a transition that is created during the change. Fluid flow after the hydraulic jump is typically rough and choppy turbulent flow.
