Enter the oxygen percentage to calculate the air to oxygen ratio. This calculator helps in determining the ratio of air needed to achieve a specific percentage of oxygen in a mixture.
Air to Oxygen Ratio Formula
The following formula is used to calculate the air to oxygen ratio:
AOR = (100 - O) / O
Variables:
- AOR is the air to oxygen ratio
- O% is the oxygen percentage in the mixture
To calculate the air to oxygen ratio, subtract the oxygen percentage from 100 and then divide by the oxygen percentage.
What is Air to Oxygen Ratio?
The air to oxygen ratio is a measure of the amount of air needed to achieve a certain level of oxygen concentration in a gas mixture. It is commonly used in various applications such as medical oxygen delivery systems, combustion processes, and environmental engineering. Understanding the air to oxygen ratio is crucial for ensuring the correct oxygen supply for medical patients or optimizing combustion in engines and furnaces.
How to Calculate Air to Oxygen Ratio?
The following steps outline how to calculate the Air to Oxygen Ratio:
- First, determine the oxygen percentage (O%) in the mixture.
- Next, use the formula AOR = (100 – O%) / O%.
- Finally, calculate the Air to Oxygen Ratio (AOR).
- After inserting the variable and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variable as an example problem to test your knowledge.
Oxygen percentage (O%) = 21%
