Question

Which hydraulic jump occurs in our sink?

(a) Inertial forces hydraulic jump

(b) Shallow fluid hydraulic jump

(c) Critical depth jump

(d) Hydraulic radius expands

This question was addressed to me in unit test.

Question is from Hydraulic Jump in section Non Uniform Flow in Channels of Fluid Mechanics

Answer 1

The correct option is (b) Shallow fluid hydraulic jump

To elaborate: Shallow fluid hydraulic jump takes place during a hydraulic jump that is created in our sink. It will undergo a smooth flow during the hydraulic jump as the flow is shallow.
