User Guide
Use this calculator to convert mass flow rate and density of a substance to the rate of volumetric flow.
When a volume flow rate is calculated a chart will be generated showing related conversion values for mass versus volume flow for the specified substance density.
Formula
The formula used by this calculator to calculate the volume flow is:
Q = ṁ / ρ
Symbols
- Q = Volumetric flow rate
- ṁ = Mass flow rate
- ρ = Density
Mass Flow Rate Measured
Enter the rate at which a quantity of substance mass will flow in a unit of time.
Density
Enter the density of the substance that is flowing
Volumetric Flow Rate Calculation
This is the volume of substance which will pass in a unit of time for the selected mass flow rate and substance density.

Calculating velocity from mass flow rate & density
I have heat exchanger in/out mass flow rate readings for a liquid, and the densities for each liquid type. I also have the pipe diameter in inches. How do I calculate the velocity?
First you need to use this ṁ / ρ = Q tool to calculate the volume flow rate by entering each mass flow rate and density value. Then you need to use this Q / (π · (ø / 2)²) = v tool to calculate the velocity by entering the previously calculated volume flow rate, and the diameter of the pipe.
