Mixed Air Calculator – Optimize HVAC Efficiency

This tool will calculate the properties of mixed air for you based on your input parameters.

How to use the Mixed Air Calculator

This calculator helps you determine the flow rates of individual gases in a mixed air supply. To use the calculator, follow these simple steps:

  • Enter the percentage of Oxygen in the supply air.
  • Enter the percentage of Nitrogen in the supply air.
  • Enter the percentage of other gases in the supply air.
  • Enter the total flow rate in liters per minute (L/min).
  • Click the Calculate button to get the results.

How it calculates the results

The calculator uses the following steps to compute the flow rates of individual gases:

  1. First, it ensures that the sum of the percentages of Oxygen, Nitrogen, and other gases equals 100%. If not, it alerts the user.
  2. It then calculates the flow rate of each gas by multiplying its percentage (divided by 100) by the total flow rate.
  3. The results are displayed showing the flow rates of Oxygen, Nitrogen, and other gases in liters per minute (L/min).

Limitations

This calculator assumes that the percentages input for Oxygen, Nitrogen, and other gases sum up perfectly to 100%. Any deviations from this can lead to inaccurate calculations. It is also designed for educational and basic calculation purposes; for critical applications, please consult with a professional.
