Enter the volumetric flow rate (m^3/s) and the density (kg/m^3) into the Calculator. The calculator will evaluate the Mass Flux. 

Mass Flux Formula

MF = VFR * D


  • MF is the Mass Flux (kg/s)
  • VFR is the volumetric flow rate (m^3/s)
  • D is the density (kg/m^3)

To calculate Mass Flux, multiply the volumetric flow rate by the material density.

How to Calculate Mass Flux?

The following steps outline how to calculate the Mass Flux.

  1. First, determine the volumetric flow rate (m^3/s). 
  2. Next, determine the density (kg/m^3). 
  3. Next, gather the formula from above = MF = VFR * D.
  4. Finally, calculate the Mass Flux.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

volumetric flow rate (m^3/s) = 30

density (kg/m^3) = 3.4
