WebFlow is different than velocity. Velocity is defined as the distance a given fluid moves within a unit of time, most commonly expressed in centimeters per second. The flow of a fluid within a tube is related to velocity by the relationship F = V ⋅ r 2, where V is the mean velocity and r is the radius of the tube. + + + WebThe first difference is that the fluid velocity is a vector, where as the fluid flow rate is not. The second is that the velocity is a well defined quantity. The fluid flow rate, on the other …
