How to calculate fluid mass flow
This calculator finds mass flow rate by multiplying fluid density by volumetric flow rate.
How the calculation works
Mass flow rate = Density × Volume flow rate.
Example
1,000 kg/m³ density at 0.05 m³/s flow: 1,000×0.05 = 50 kg/s.

Pro Tips for Fluid Mass Flow
- Keep density and flow rate in compatible units for a correct result.
- Mass flow rate is constant through a pipe of varying cross-section (for incompressible flow), unlike velocity, which changes with area.
Common Fluid Mass Flow Mistakes to Avoid
- Confusing mass flow rate with volumetric flow rate, which are related but different quantities.
