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
