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)

To calculate air volume, multiply the volumetric air flow (ft^3/min) by the total time.

## How to Calculate Air Volume?

The following example problems outline how to calculate Air Volume.

Example Problem #1:

1. First, determine the volumetric air flow (CFM).
1. The volumetric air flow (CFM) is given as: 30.
2. Next, determine the total time (minutes).
1. The total time (minutes) is provided as: 5.
3. 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)
