User Guide

This tool will calculate the volumetric flow rate in any units from the specified velocity of a substance flowing through a defined cross-sectional area. For each new calculation a unique conversion scale will be generated for the range of flow velocities and volumetric flow rates with the cross sectional area specified.

Formula

The volumetric flow rate formula used by this calculator is:

Q = v · A

Symbols

  • Q = Volume flow rate
  • v = Flow velocity
  • 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.

Flow Velocity Measured

Enter the speed at which the substance is moving.

Cross-Sectional Area

Enter the size of the area perpendicular to the direction of flow.

Volumetric Flow Rate Calculation

This is the amount of volume that will flow pass per unit of time.
