Recoil Velocity Calculator:>
Enter the values of Recoil Force RF(lbf) , Mass of the bullet M(lbs) & Recoil Distance RD(inches) to determine the value of Recoil Velocity Vr(ft/s).
Recoil Velocity Formula:
The Recoil Velocity Vr(ft/s) in Feet per Second is equal to the SQRT of the Recoil Force RF(lbf) in lbf is Divided by the Mass of the bullet M(lbs) in lbs into multiply the product of the Recoil Distance RD(inches) in inches to divided by the value of 12 and again divided by the value of 32.174049.
The Equation of Recoil Velocity can be writtern as,
Vr(ft/s) = SQRT ( RF(lbf) / M(lbs) * ( RD(inches) /12 ) / 32.174049
Here,
Vr(ft/s) = Recoil Velocity in Feet per Second
RF(lbf) = Recoil Force in lbf
M(lbs) = Mass of the bullet in lbs
RD(inches) = Recoil Distance in inches
Calculation for Recoil Velocity:
1)Determine the Recoil Velocity and given for Recoil Force = 50lbf , Mass of the bullet = .00010 lbs , Recoil Distance = 5inches.
Answer
Vr = √ ( RF / M * ( RD / 12 ) / 32.174049 )
Vr = √ ( 50 / .00010 * ( 5 / 12 ) / 32.174049 )
Vr = 80.46ft/s.
2)Determine the Recoil Distance and given for Recoil Force = 50lbf , Mass of the bullet = .00010 lbs , Recoil Velocity = 80.46ft/s.
Answer
Vr = √ ( RF / M * ( RD / 12 ) / 32.174049 )
80.46 = √ ( 50 / .00010 * ( RD / 12 ) / 32.174049 )
RD = 5inches.
