Air Usage Formula

The following formula is used to calculate the air usage.

AU = FR * OT

Variables:

  • AU is the air usage (cubic feet)
  • FR is the flow rate of air (cubic feet per minute)
  • OT is the operating time (minutes)

To calculate the air usage, multiply the flow rate of air by the operating time.

What is Air Usage?

Air usage is the volume of air consumed by a pneumatic system or process over a given period of time. It is a critical parameter for designing and operating compressed air systems, as it affects the sizing of compressors and the efficiency of the system. Understanding air usage helps in optimizing performance and reducing energy costs associated with compressed air systems.

How to Calculate Air Usage?

The following steps outline how to calculate the Air Usage.

  1. First, determine the flow rate of air (FR) in cubic feet per minute.
  2. Next, determine the operating time (OT) in minutes.
  3. Next, gather the formula from above = AU = FR * OT.
  4. Finally, calculate the Air Usage (AU) in cubic feet.
  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.

Flow rate of air (FR) = 15 cubic feet per minute

Operating time (OT) = 60 minutes
