What is the Linear Velocity Calculator?

The Linear Velocity Calculator estimates fluid linear velocity from flow rate and circular cross-sectional size. It is useful when radius or diameter is given in mm, cm, or m, while the flow rate is provided in practical laboratory units such as µL/min or mL/min.

This tool can be used for columns, tubes, channels, and other cylindrical flow paths. BioChemCalc provides this calculator free of charge in a browser-based format.

Linear velocity is calculated as v = Q / A, where Q is the volumetric flow rate and A is the cross-sectional area.
