## Muzzle Velocity Formula

The following equation is used to calculate the .

V = SQRT (2*KE/(M/7000))

- Where V is the muzzle velocity (ft/s)
- KE is the muzzle energy (lbf-foot)
- M is the mass of the bullet (grains)

To calculate the muzzle velocity, multiply the kinetic energy by 2, divide by the mass, then take the square root of the result.

## What is a Muzzle Velocity?

Definition:

A muzzle velocity is a measure of the total speed of the muzzle after the firing of a bullet.

## How to Calculate Muzzle Velocity?

Example Problem:

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

First, determine the muzzle energy. In this example, the muzzle energy is found to be 10 lbf-ft.

Next, determine the mass of the bullet. For this problem, the mass of the bullet is found to be 20 grains.

Finally, calculate the Muzzle Velocity using the formula above:

V = SQRT (2*KE/(M/7000))

V = SQRT (2*10/(20/7000))

V = 83.66 ft/s
