**Formula:**`Fr > 1: E = √Fr`

## Introduction to Hydraulic Jump Energy Dissipation

The hydraulic jump is a natural rapid energy dissipation process that occurs in open channel flow. The Froude number (Fr) is a dimensionless number used to determine the regime of the flow; when Fr > 1, it indicates supercritical flow and the jump occurs. The energy dissipation can be calculated using the formula E = √Fr, where E is the energy dissipation and Fr is the Froude number. The hydraulic jump phenomenon is important in hydraulic engineering for designing hydraulic structures and controlling flows.

## Parameter usage:

`Fr`

= Froude number

## Output:

`E`

= energy dissipation

## Data validation

The Froude number should be greater than 1 for energy dissipation to occur.

## Summary

This formula calculates the energy dissipation in a hydraulic jump based on the Froude number of the flow. It is important for assessing and designing hydraulic structures and controlling open channel flows.
