User Guide

This tool will calculate the speed of the flow in any units from the specified volumetric flow rate for a substance passing through a known cross-sectional area. For each calculated flow speed a conversion scale will be displayed with a range of values for flow versus speed for the same cross sectional area.

Formula

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 the entire cross-sectional area, without any friction losses near to surfaces.

Volumetric Flow Rate Measured

Enter the required amount of volume needed to flow pass per unit of time.

Cross-Sectional Area

Enter the cross-sectional area perpendicular to the direction of flow of the substance through a pipe, duct or channel at the point of measurement.

Flow Velocity Calculation

This is the speed of flow that will be produced by the specified volumetric flow rate and cross-sectional area
