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. + + + WebFormula The formula used by this calculator to calculate the flow velocity is: v = Q / A Symbols v = Flow velocity Q = Volumetric flow rate A = Cross-sectional area n.b. This formula assumes uniform flow conditions within …

Given a flowrate, a larger pipe will have a lower velocity, and a small pipe will have a higher velocity. This concept is critical to understanding the hydraulics of pipeline design because friction and turbulence are mostly a result of flow velocity. churches in elk city ok
