The optimal length of a rifle barrel

Name: Work Video:
Duration: 3 min 30 s
Description: A simple thermodynamic model for projectile propulsion inside a rifle barrel results in a functional relationship between the muzzle speed of the rifle and its barrel length. This relationship is in excellent agreement with the existing experimental data over a wide range of barrel lengths. PACS No.: 45.40.Gj, 89.00
