## What is the critical depth of flow?

Critical Flow: The variation of specific energy with depth at a constant discharge shows a minimum in the specific energy at a depth called critical depth at which the Froude number has a value of one.

Critical depth is also the depth of maximum discharge, when the specific energy is held constant..

## What is alternate depth?

Alternate depths are defined as the depths of flow in open channels for which the specific energy is the same. … The derived equation would be helpful in practical studies dealing with the open-channel flows, especially in the cases of transitions in width and bottom elevation of the channel.

## What is Section factor in open channel flow?

The section Factor for critical flow The section factor for critical flow computation (Z) is the product of the water area and the square root of the hydraulic depth.

## How do you calculate alternate depth?

The depths of flow can be either PR = y1 or PR` = y`1. These two possible depths having the same specific energy are known as alternate depths.

## What is the critical depth denoted as?

Critical flow relationships The critical depth has a Froude number equal to one and corresponds to the minimum energy a flow can possess for a given discharge.

## What is the difference between open channel flow and pipe flow?

Open channel flow is subjected to atmospheric pressure while pipe flow is not (when pipe is full). Open channel flow is not completely enclosed by boundaries, unlike pipe flow. Open channel is always under the action of gravity, while pipe can be under gravity or may flow due to some external pressure.

## What is critical depth in open channel flow?

Normal depth is the depth of flow that would occur if the flow was uniform and steady, and is usually predicted using the Manning’s Equation. Critical depth is defined as the depth of flow where energy is at a minimum for a particular discharge. Flow profiles are classified by the slope of the channel (So), yn, and yc.

## What is depth of flow?

Normal depth is the depth of flow in a channel or culvert when the slope of the water surface and channel bottom is the same and the water depth remains constant. … Normal depth is undefined for culverts placed at horizontal or adverse slopes.

## What is the normal depth denoted as?

6. What is the normal depth denoted as? Explanation: Normal depth is denoted as Yn. The normal depth plays an important role in determining the hydraulic slope and hydraulic curve of a fluid flow in motion.

## What is Sequent depth?

Conjugate, or sequent, depths are the paired depths that result upstream and downstream of a hydraulic jump, with the upstream flow being supercritical and downstream flow being subcritical.
