Enter the volume of CO2 gas and the time taken into the calculator to determine the CO2 flow rate. This calculator can also evaluate any of the variables given the others are known.

Co2 Flow Rate Formula

The following formula is used to calculate the CO2 flow rate.

FR = V / T *D
  • Variables:

  • FR is the CO2 flow rate (kg/s)

  • V is the volume of CO2 gas (m^3)

  • T is the time taken

To calculate the CO2 flow rate, divide the volume of CO2 gas by the time taken. The result will be the flow rate of CO2 in kilograms per second.

What is a Co2 Flow Rate?

A CO2 flow rate refers to the speed or volume at which carbon dioxide (CO2) is moving through a particular system over a specific period of time. It is often measured in terms of volume per unit of time, such as liters per minute (L/min) or cubic feet per minute (CFM). This measurement is crucial in various applications, including industrial processes, medical procedures, and environmental studies, to ensure proper functioning and safety.

How to Calculate Co2 Flow Rate?

The following steps outline how to calculate the CO2 Flow Rate.


  1. First, determine the volume of CO2 gas (V) in cubic meters (m^3).
  2. Next, determine the time taken (T) in seconds (s).
  3. Next, gather the formula from above = FR = V / T.
  4. Finally, calculate the CO2 Flow Rate (FR) in kilograms per second (kg/s).
  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.

Volume of CO2 gas (V) = 10 m^3

Time taken (T) = 5 seconds
