Question

Energy is not conserved throughout the hydraulic jump.

(a) True

(b) False

I had been asked this question in class test.

I'm obligated to ask this question of Location of a Hydraulic Jump topic in chapter Non Uniform Flow in Channels of Fluid Mechanics

Answer 1

Correct choice is (a) True

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. Though momentum is conserved throughout the hydraulic jump, energy is not conserved.
