Enter the total cubic feet per minute (CFM) and the cross-sectional area (ft^2) into the FPS from CFM Calculator. The calculator will evaluate the FPS from CFM.
FPS from CFM Formula
The following two example problems outline the steps and information needed to calculate the FPS from CFM.
FPS = CFM / A /60
Variables:
- FPS is the FPS from CFM (ft/s)
- CFM is the total cubic feet per minute (CFM)
- A is the cross-sectional area (ft^2)
To calculate FPS from CFM, divide the CFM by the cross-sectional area, then divide again by 60.
How to Calculate FPS from CFM?
The following steps outline how to calculate the FPS from CFM.
- First, determine the total cubic feet per minute (CFM).
- Next, determine the cross-sectional area (ft^2).
- Next, gather the formula from above = FPS = CFM / A /60.
- Finally, calculate the FPS from CFM.
- 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.
total cubic feet per minute (CFM) = 250
cross-sectional area (ft^2) = 15
FPS = CFM / A /60 = ?
