Ballistic Coefficient - Formula

Formula

where:

  • BCPhysics = ballistic coefficient as used in physics and engineering
  • M = mass
  • A = cross-sectional area
  • Cd = drag coefficient
  • ρ (rho) = average density
  • l = body length

This definition is not the same as the BC used by bullet manufacturers. This is the BC as defined by and used in physics and engineering. Although it would not be incorrect to describe the behavior of bullets using this equation, the BC obtained from this equation would not give the same value as the BC from a bullet manufacturer because their value is a comparison to the G1 bullet model.

Famous quotes containing the word formula:

    So, if we must give a general formula applicable to all kinds of soul, we must describe it as the first actuality [entelechy] of a natural organized body.
    Aristotle (384–323 B.C.)

    For the myth is the foundation of life; it is the timeless schema, the pious formula into which life flows when it reproduces its traits out of the unconscious.
    Thomas Mann (1875–1955)

    I take it that what all men are really after is some form or perhaps only some formula of peace.
    Joseph Conrad (1857–1924)
