Enter your volume flow rate and density into the calculator to determine the mass flow rate.

Mass Flow Rate Calculation Formula

The following formula is used to calculate the mass flow rate from the volume flow rate and density.

Mass Flow Rate = Volume Flow Rate * Density

Variables:

  • Mass Flow Rate is the mass of fluid passing a point per unit time (kg/s)
  • Volume Flow Rate is the volume of fluid passing a point per unit time (m³/s)
  • Density is the mass per unit volume of the fluid (kg/m³)

To calculate the mass flow rate, multiply the volume flow rate by the density.

What is Mass Flow Rate Calculation?

Mass flow rate calculation refers to the process of determining the mass of a fluid that flows through a given surface per unit time. This involves understanding the volume flow rate and the density of the fluid. Proper mass flow rate calculation is essential for various applications in engineering, fluid mechanics, and process industries.
