# Muzzle Velocity Calculator, Formula, Muzzle Velocity Calculation

## Muzzle Velocity Calculator:>

Enter the values of Muzzle energy KE(lbf-foot) & Mass of the Bullet M(grains)  to determine the value of Muzzle velocity V(feet/second).

 Enter Muzzle Energy: lbf-foot Enter Mass of the Bullet: grains Result – Muzzle Velocity: feet/second

## Muzzle Velocity Formula:

The Muzzle velocity V(feet/second) in feet per second is equal to the SQRT of the value of 2 into multiply the Muzzle energy KE(lbf–foot) in lbf-foot to divided by the Mass of the Bullet M(grains) in grains and again divided by the value of 7000.

The Formula of Muzzle velocity can be writtern as,

V(feet/second) = SQRT ( 2 * KE(lbf-foot) / ( M(grains) / 7000 ) )

Here,

V(feet/second) = Muzzle velocity in feet per second

KE(lbf-foot) = Muzzle energy in lbf-foot

M(grains) = Mass of the Bullet in grains

### Calculation for Muzzle velocity:

1)Determine the Muzzle velocity and given for Muzzle energy = 8lbf-foot ,  Mass of the Bullet = 20grains.

V = √ ( 2 * KE / ( M / 7000 ) )

V = √ ( 2 * 8 / ( 20 / 7000 ) )

V = 74.83ft/s.

2)Determine the Mass of the Bullet and given for Muzzle energy = 8lbf-foot , Muzzle velocity = 74.83ft/s.
