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
