Question

Give an example of man-made hydraulic jumps?

(a) Normal

(b) Low

(c) High

(d) Zero

This question was posed to me during an online interview.

I want to ask this question from Location of a Hydraulic Jump in portion Non Uniform Flow in Channels of Fluid Mechanics

Answer 1

Correct answer is (b) Low

To explain I would say: 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.
