Volumetric Flow Rate Converter

The volumetric flow rate, also known as the volume flow rate or rate of fluid flow, is the amount of fluid that moves through a specific volume per unit of time, such as cubic meters per second (m3/s) in standard SI units or feet per second (ft3/s). Usually, the letter Q is used to denote it. Volumetric flux, represented by the symbol q and measured in [m3/(m2s)], should not be confused with volumetric flow rate. The volumetric flow rate is obtained by integrating a flux across a particular region. Viscosity is also related to volumetric flow rate.

Surprisingly, our flow rate calculator helps solve problems outside of fluid mechanics. You can use it to determine the flow rate of a garden hose or shower head and the cardiac output or how much blood your heart pumps per minute. It can also be used as a basic calculation for pipe velocities.

You may find a section below explaining flow rate and a paragraph describing how to calculate flow rate to understand the subject thoroughly. Be cautious because the word "flow rate" itself can be confusing! We've incorporated two flow rate formulas, which is fortunate because you're protected in both scenarios. Our tool can calculate both the mass flow rate and the volumetric flow rate.

To calculate the empty field, enter the flow velocity or volumetric flow rate together with the column diameter. To clear the fields, click the reset button.

Volumetric flow rate (L/h) = (flow velocity (cm/h) * (column crossectional area (cm2) /1000) yields the empty field.
