How to use Muzzle-velocity in a sentence
After all care has been taken in laying and pointing, in accordance with the rules of theory and practice, absolute certainty of hitting the same spot every time is unattainable, as causes of error exist which cannot be eliminated, such as variations in the air and in the muzzle-velocity, and also in the steadiness of the shot in flight.
This muzzle velocity is about 5% greater than the 2150 f/s of the range table, so on these considerations we may suppose about 10% of work is lost by friction in the bore; this is expressed by saying that the factor of effect is f =0.9.
The heavy, blunt-nosed lead bullet, nearly half an inch in diameter, had a muzzle velocity of 600ft per second.
But the 245 m/s muzzle velocity of these weapons was far too low, and they failed in combat.Advertisement
