WebFor each new calculation a unique conversion scale will be generated for the range of volumetric flow rates and flow speeds for the diameter specified. Formula. The flow velocity formula used by this calculator is: v = Q / (π · (ø / 2)²) Derived from: v = Q / A. A = π · r². r = ø / 2. Symbols. Q = Volume flow rate; v = Flow velocity; A ... WebIn order to determine the Flow Rate represented as Q, we must define both the volume V and the point in time it is flowing past represented by t, or Q = V/t. Additionally Flow rate and velocity are related by the equation Q = …
