Duct Volume Calculator

Formula

To calculate the duct volume:

\[ Vd = CSA \times L \]

Where:

\(Vd\) is the duct volume (ft³)
\(CSA\) is the duct cross-sectional area (ft²)
\(L\) is the duct length (ft)

What is Duct Volume?

Duct volume is the total volume of air that a duct can hold, calculated by multiplying the cross-sectional area of the duct by its length. This measurement is important in HVAC (Heating, Ventilation, and Air Conditioning) systems to ensure proper airflow and system efficiency.

Example Calculation 1

Let's assume the following values:

Duct Cross-Sectional Area (CSA) = 2 ft²
Duct Length (L) = 10 ft

Using the formula:

\[ Vd = 2 \times 10 = 20 \text{ ft³} \]

The Duct Volume is 20 ft³.

Example Calculation 2

Let's assume the following values:

Duct Cross-Sectional Area (CSA) = 1.5 ft²
Duct Length (L) = 15 ft

Using the formula:

\[ Vd = 1.5 \times 15 = 22.5 \text{ ft³} \]

The Duct Volume is 22.5 ft³.
