## 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 critical depth meter?

Critical depth meter is used to measure; 1) Discharge in an open channel. 2) Hydraulic jump.

## 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 critical depth in open channel?

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.

## How do you calculate critical depth?

The critical depth for a rectangular channel can be calculated from the fact that the Froude number is equal to one at critical flow conditions. For a rectangular channel , this fact leads to the equation: Vc/(gyc)1/2 = 1, where the subscript c is used to indicate critical flow conditions for the velocity and depth.

## How do you calculate flow depth in a pipe?

Solution: The given parameters are depth of flow: y = 4 inches and pipe diameter: D = 12 inches. Thus y/D = 4/12 = 0.3333. Since y/D is between 0.3 and 0.5, the equation for n/nfull is: n/nfull = 1.29 – (y/D – 0.3)(0.2), as shown above.

## What is the critical depth?

Critical depth is defined as the depth of flow where energy is at a minimum for a particular discharge.

## What is meant by hydraulic jump?

A hydraulic jump is a phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillways. When liquid at high velocity discharges into a zone of lower velocity, a rather abrupt rise occurs in the liquid surface.

## How is the critical depth affected by Q?

How critical depth is affected by the Q? As shown in the results, when the flow rate (Q) is lower, the critical depth is shallower. When the flow rate (Q) is higher, the critical depth is deeper.

## What is Hydraulic depth?

For use in Froude number and energy relationships in open channel flow hydraulics, mean depth, hm, is defined as the depth which, when multiplied by the top water surface width, T, is equal to the irregular section area, A, shown on figures 2-4a and 2-4b, of the flow section and is commonly used for critical flow …

## 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.
