Question

Which among the following is not the purpose of a hydraulic jump?

(a) Mix chemicals

(b) Dissipate heat

(c) Increasing temperature and pressure

(d) Aeration device

I had been asked this question in quiz.

The above asked question is from Location of a Hydraulic Jump topic in chapter Non Uniform Flow in Channels of Fluid Mechanics

Answer 1

The correct option is (c) Increasing temperature and pressure

To explain: 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. This transition leads to mixing of chemicals, dissipating heat and used in aeration devices.
