Why Calculate Duct Volume?

Understanding the volume of your ductwork is crucial for several reasons:

• System Efficiency: Properly sized ducts ensure efficient airflow and system performance.
• Material Estimation: Knowing the volume helps in estimating the amount of insulation or other materials needed.
• Cost Calculation: Accurate volume calculations can aid in budgeting for projects by determining material and installation costs.

How to Use the Duct Volume Calculator?

1. Select Duct Shape: Choose either "Rectangular" or "Circular" from the options provided.

2. Enter Dimensions: Input the required dimensions for your chosen duct shape.
   • For Rectangular Ducts: Enter the width, height, and length.
   • For Circular Ducts: Enter the diameter and length.
3. Calculate: Click on the "Calculate" button to get the volume of the duct.

Rectangular Duct Volume Calculation

To calculate the volume of a rectangular duct, use the following formula:

$\text{Volume}=\text{Width}\times \text{Height}\times \text{Length}$

Example: If a rectangular duct has a width of 2 feet, a height of 1.5 feet, and a length of 10 feet, the volume would be:

$\text{Volume}=$2 ft×1.5 ft×10 ft=30 cubic feet

Circular Duct Volume Calculation

To calculate the volume of a circular duct, use the following formula:$$

$Volume=\pi {\left(\frac{\text{Diameter}}{2}\right)}^2\times \text{Length}$

Example: If a circular duct has a diameter of 3 feet and a length of 10 feet, the volume would be:

$\text{Volume}=3.14159{\left(\frac{\text{3 ft}}{2}\right)}^2\times \text{10ft}$

Volume = 70.69 cubic feet
