Enter the volume flow rate and the diameter of the natural gas pipe into the calculator to determine the natural gas velocity.

## Natural Gas Velocity Formula

The following equation is used to calculate the Natural Gas Velocity.

NGV = Q / (pi*D^2/4)

• Where NGV is the Natural Gas to Velocity (m/s)
• Q is the volumetric flow rate (m^3/s)
• D is the internal diameter of the natural gas pipe (m)

## What is a Natural Gas Velocity?

Definition:

A natural gas velocity is a measure of the linear rate of speed of natural gas moving through a pipe.

## How to Calculate Natural Gas Velocity?

Example Problem:

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

First, determine the volumetric flow rate. In this example, the flow is found to be 600 m^3/s.

Next, determine the internal diameter of the natural gas pipe. For this problem, the internal diameter of the natural gas pipe is found to be 1.2m.

Finally, calculate the Natural Gas Velocity using the formula above:

NGV = Q / (pi*D^2/4)

NGV = 600 / (3.14159*1.2^2/4)

NGV = 530.31 m/s
