Calculate CFM From Differential Pressure (CFM)



Formula

The formula to calculate the CFM from differential pressure is:

\[ CFM = 4005 \times \sqrt{dP} \times A \]

What is CFM From Differential Pressure?

CFM from differential pressure is a measure of the airflow rate calculated based on the differential pressure across a known cross-sectional area. It is commonly used in HVAC systems to determine the airflow through ducts and vents.

Example

For example, if the differential pressure (dP) is 0.5 W.C. and the cross-sectional area (A) is 2 ft², the CFM can be calculated as follows:

\[ CFM = 4005 \times \sqrt{0.5} \times 2 = 4005 \times 0.707 \times 2 \approx 5664.14 \text{ ft³/min} \]

So, the CFM from differential pressure for these values is approximately 5664.14 ft³/min.
