This note presents a general formula for the terminal velocity of a sphere in a viscous fluid (no wall effects). The formula holds for Reynolds numbers up to 2000 and it has an accuracy better than 2% (so far as can be checked against experimental data with errors of the same order of...

We now give the specific formula for updating the values of velocity and position. The velocity of each particle is calculated from the following equation at time t; in practice the t values are equivalent to the iteration or generation number of the process, starting with t=0: (3.2)vi(t...
It is one of the fundamental concepts in classical mechanics that considers the motion of bodies. If you want to put this rule down in the form of a mathematical formula, the velocity equation will be as follows: velocity = distance / time Keep in mind that this velocity formula only ...
If the structure through which air is flowing is a cylindrical tube, for example, the area across which air moves is circular and given by the formula for the area of a circle: A=πr2 where r is the radius of the cylinder. ...
