If s = n d, divide both sides of the equation by d: When a disk in contact with a surface rotates, the shaft around which the disk is spinning moves forward only if the force of friction between the disk and surface is large enough to prevent slipping. << Second, its crucial that you think about units when youre calculating rpm. The answer is 9.5492965964254. If the twist rate is given as 1 per a length in millimeters and the muzzle velocity is given in meters per second (m/s), you multiply the muzzle velocity by 1000 to convert it to millimeters per second (mm/s). To put it another way, its the number of times something spins per minute.
