Enter the total mass (kg) and the total time (s) into the Mass Flow Rate Calculator. The calculator will evaluate the Mass Flow Rate. 

Mass Flow Rate Formula

The following two example problems outline the steps and information needed to calculate the Mass Flow Rate.

MFR = M / T

  • Where MFR is the Mass Flow Rate (kg/s)
  • M is the total mass (kg) 
  • T is the total time (s) 

How to Calculate Mass Flow Rate?

The following example problems outline how to calculate Mass Flow Rate.

Example Problem #1:

  1. First, determine the total mass (kg). 
    • The total mass (kg) is given as: 500.
  2. Next, determine the total time (s). 
    • The total time (s) is provided as: 30.
  3. Finally, calculate the Mass Flow Rate using the equation above: 

MFR = M / T

The values provided above are inserted into the equation below and computed.

MFR = 500 / 30 = 16.667 (kg/s)


Example Problem #2: 

For this problem, the variables required are provided below:

total mass (kg) = 100

total time (s) = 10

Test your knowledge using the equation and check your answer with the calculator..

MFR = M / T = ?
