Enter the volumetric air flow (CFM) and the total time (minutes) into the Air Volume Calculator. The calculator will evaluate and display the Air Volume.

## Air Volume Formula

The following formula is used to calculate the Air Volume.

**AV = AF * T**

- Where AV is the Air Volume (ft^3)
- AF is the volumetric air flow (CFM)
- T is the total time (minutes)

## How to Calculate Air Volume?

The following example problems outline how to calculate Air Volume.

Example Problem #1:

- First, determine the volumetric air flow (CFM).
- The volumetric air flow (CFM) is given as: 30.

- Next, determine the total time (minutes).
- The total time (minutes) is provided as: 5.

- Finally, calculate the Air Volume using the equation above:

AV = AF * T

The values given above are inserted into the equation below:

AV = 30 * 5 = 150 (ft^3)

Example Problem #2:** **

The variables needed for this problem are provided below:

volumetric air flow (CFM) = 6

total time (minutes) = 8

Entering these values and solving gives:

AV = 6 * 8 = 48 (ft^3)
