The formula to calculate the FPS from CFM is:
\[ FPS = \frac{CFM}{A \times 60} \]
Where:
Let's say the total cubic feet per minute (CFM) is 600 and the cross-sectional area (A) is 2 square feet. Using the formula:
\[ FPS = \frac{600}{2 \times 60} \]
We get:
\[ FPS = 5\, \text{ft/s} \]
So, the feet per second (FPS) is 5 ft/s.
