Calculate Duct Weight









Formula

To calculate the weight of a duct:

\[ DW = ((2 \cdot (H + W)) \cdot L \cdot T) \cdot D \]

What is Duct Weight?

The weight of a duct is calculated based on its dimensions (height, width, length, and thickness) and the density of the material used. This calculation helps in determining the load-bearing capacity required and the overall structural support needed for the ductwork in construction or HVAC systems.

Example Calculation 1

Let's assume the following values:

Use the formula:

\[ DW = ((2 \cdot (10 + 12)) \cdot 20 \cdot 0.5) \cdot 1 = (2 \cdot 22 \cdot 20 \cdot 0.5) \cdot 1 = 440 \text{ lbs} \]

The duct weight is 440 lbs.

Example Calculation 2

Let's assume the following values:

Use the formula:

\[ DW = ((2 \cdot (8 + 10)) \cdot 15 \cdot 0.75) \cdot 1.2 = (2 \cdot 18 \cdot 15 \cdot 0.75) \cdot 1.2 = 486 \text{ lbs} \]

The duct weight is 486 lbs.
