| Mark-45 firing on the deck of a destroyer. |
Today I was mindful of the fluid behavior that takes place in a gunshot. There are several fluid principles at work here. First, there is a rapid expansion of gas due due the gunpowder that is ignited to fire the projectile. This sudden expansion carries with it a loss in energy (head loss). This flow is obviously turbulent due to the extremely high velocities coming out of the end of the barrel. The projectile produces a sonic boom caused by the supersonic speeds that the projectile is moving at.
