I have been asked this question in an international level competition.

My doubt is from Location of a Hydraulic Jump topic in section Non Uniform Flow in Channels of Fluid Mechanics

Answer 1

The correct answer is (a) True

The explanation is: 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. Height of the hydraulic is similar to its length and is used to know the design of water structures.
