## Water Velocity Formula

The following equation is used to calculate the Water Velocity.

Vw = WFR / A

- Where Vw is the water velocity (ft/s)
- WFR is the volumetric water flow rate (ft^3/s)
- A is the cross-sectional area of flow (ft^2)

## What is a Water Velocity?

Definition:

Water velocity describes the linear speed at which water flows through an enclosed volume.

## How to Calculate Water Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Water Velocity.

First, determine the volumetric water flow rate. In this example, the volumetric water flow rate is found to be 300 ft^3/s.

Next, determine the cross-sectional area of the flow. For this problem, the area is found to be 30 ft^2.

Finally, calculate the Water Velocity using the formula above:

Vw = WFR / A

Vw = 300 / 30

Vw = 10 ft/s
