Question

Normal depth occurs only for a uniform and steady flow.

(a) True

(b) False

This question was addressed to me in quiz.

I'd like to ask this question from Characteristics of Surface Profiles in chapter Non Uniform Flow in Channels of Fluid Mechanics

Answer 1

Right answer is (a) True

To explain: Normal depth occurs only for a uniform and steady flow. Normal depth is a depth of flow in the channel. It is created when the slope of the water surface and channel bottom is the same and the water depth remains the same throughout the entire flow.
