Air Volume Formula:
| From: | To: |
The air volume calculation formula (V = A × L) calculates the volume of air space by multiplying the cross-sectional area by the length. This fundamental formula is widely used in ventilation, HVAC systems, ductwork design, and airflow calculations.
The calculator uses the air volume formula:
Where:
Explanation: This formula calculates the volume of air contained within a space by multiplying the area of the cross-section by the length of the space in the direction of airflow.
Details: Accurate air volume calculation is essential for proper ventilation system design, determining airflow requirements, calculating air changes per hour, and ensuring adequate indoor air quality in buildings and industrial spaces.
Tips: Enter cross-sectional area in square meters (m²) and length in meters (m). Both values must be positive numbers greater than zero for accurate calculation.
Q1: What units should I use for the inputs?
A: Use square meters (m²) for area and meters (m) for length to get volume in cubic meters (m³). You can convert from other units before entering values.
Q2: Can this formula be used for irregular shapes?
A: This formula works best for uniform cross-sections. For irregular shapes, use the average cross-sectional area or divide into regular sections and sum the volumes.
Q3: How is air volume used in HVAC calculations?
A: Air volume is fundamental for determining airflow rates, duct sizing, fan selection, and calculating air changes per hour for ventilation requirements.
Q4: What if the cross-section changes along the length?
A: For tapered or varying cross-sections, calculate the volume by integrating the area function along the length or use the average cross-sectional area.
Q5: Can I use this for liquid volumes too?
A: Yes, this formula works for any fluid volume calculation where you have a consistent cross-sectional area and length, regardless of the fluid type.
