Calculate Pa to CFM



Formula

The formula to calculate the conversion from Pascal (Pa) to Cubic Feet per Minute (CFM) is:

\[ CFM = \frac{Pa \cdot A}{471.9474} \]

Where:

What is Pa to CFM?

Pa to CFM is a conversion from Pascal (Pa), a unit of pressure measurement, to Cubic Feet per Minute (CFM), a unit of flow rate measurement. This conversion is often used in various fields such as HVAC (heating, ventilation, and air conditioning) to determine the volume of air flow (in CFM) that can be moved or is required to maintain a certain pressure (in Pa). The conversion requires additional information such as the area of the duct or opening through which the air is flowing.

Example Calculation

Let's assume the following values:

Using the formula:

\[ CFM = \frac{500 \cdot 2}{471.9474} \approx 2.12 \text{ Cubic Feet per Minute} \]

The Flow Rate (CFM) is approximately 2.12 Cubic Feet per Minute.
