In physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. However, the object's speed, v, is just s divided by t, so the equation breaks down to.

Power draw is related directly to mill length, and, empirically to the diameter to the power 2.34. Theoretically, this exponent should be 2.5 (Bond, 1961). Power draw is directly related to mill speed (in r.p.m., or, fraction of critical speed) over the normal operating range.
