Air Velocity Calculator


About Air Velocity Calculator (Formula)

The Air Velocity Calculator is a useful tool for engineers and professionals in various industries to determine the speed at which air is flowing within a duct, pipe, or other enclosed spaces. It’s essential for assessing air circulation, ventilation, and HVAC system performance.

The formula for calculating air velocity involves dividing the volumetric flow rate of air by the cross-sectional area of the duct or pipe.

The formula for air velocity is:

Velocity = Volumetric Flow Rate / Cross-Sectional Area

Let’s explain each component of the formula:

  1. Velocity: This represents the air velocity, typically measured in meters per second (m/s) or feet per minute (ft/min).
  2. Volumetric Flow Rate: The rate at which air flows through the duct or pipe, usually measured in cubic meters per second (m³/s) or cubic feet per minute (CFM).
  3. Cross-Sectional Area: The area through which the air is flowing, typically measured in square meters (m²) or square feet (ft²).

The Air Velocity Calculator is crucial for designing and analyzing various systems that involve air movement, such as HVAC systems, industrial ventilation, and exhaust systems.

Using the calculator, engineers can ensure that air velocity meets design specifications, achieve efficient air distribution, and optimize system performance for comfort, safety, and energy efficiency.

It’s important to note that air velocity can vary based on factors such as duct size, shape, surface roughness, and air density.

Overall, the Air Velocity Calculator supports professionals in assessing and managing air movement within enclosed spaces, contributing to effective ventilation and efficient operation of various systems.
