Note:

This calculator determines the Air Flow Rate, which is used in ventilation systems to measure how much air is moving through a given area over time.

This formula is essential for ventilation design and monitoring to ensure adequate airflow in spaces like industrial buildings, HVAC systems, and laboratories.

How to use this calculator:

• Velocity (m/s): Enter the speed at which air is moving.
  A velocity of 0 means no air is moving, so no flow rate exists.
• Area (m²): Enter the cross-sectional area through which air flows.
  An area of 0 means there is no opening for air to pass through, making flow impossible.
