# Water Velocity Calculator

The speed at which water flows is called as the velocity of water. This online calculator is used to find the velocity of water in a pipe with the flow rate and diameter of the pipe. Flow rates are usually measured by the volume of water that passes each minute. This flow rate can be converted to velocity with the diameter of the pipe.

## Velocity of Water in Pipe Calculation

The speed at which water flows is called as the velocity of water. This online calculator is used to find the velocity of water in a pipe with the flow rate and diameter of the pipe. Flow rates are usually measured by the volume of water that passes each minute. This flow rate can be converted to velocity with the diameter of the pipe.

Code to add this calci to your website

#### Formula:

v = ( 0.4085 * f ) / ( d^{2} )
**Where,**
v = Velocity
f = Flow Rate
d = Diameter of pipe
### Example

#### Water Velocity

**Consider the flow rate as 20 gpm and diameter of the pipe as 30 inches, then the **

Water Velocity = ( 0.4085 * 20 ) / ( 30^{2} )

= ( 8.17 ) / 900

= 0.009077

Therefore, the Water Velocity is 0.009077 fps
