User Guide
This tool will calculate the cross-sectional area that a substance is flowing through from the rate of volume flow and the speed of the flow. A range of conversion values for flow and area will also be displayed for each set of input parameters entered.
Formula
The formula used by this calculator to calculate the cross-sectional flow area is:
A = Q / v
Symbols
- A = Cross-sectional area
- Q = Volumetric flow rate
- v = Flow velocity
n.b. This formula assumes uniform flow conditions within the entire cross-sectional area, without any friction losses near to surfaces.
Volumetric Flow Rate Required
Enter the quantity of volume which will flow through per unit of time.
Flow Velocity Measured
Enter the speed that the substance is moving through the flow area.
Cross-Sectional Area Calculation
This is the cross-sectional area that would be needed for a substance moving at the specified speed and rate of volumetric flow.
