Duct Velocity Calculator


About Duct Velocity Calculator (Formula)

The Duct Velocity Calculator is a tool used to calculate the velocity of air or fluid flow through a duct or pipe. Duct velocity is a crucial parameter in HVAC (heating, ventilation, and air conditioning) systems, industrial processes, and fluid transport applications. The formula for calculating duct velocity is as follows:

Duct Velocity = Flow Rate / Cross-sectional Area


  • Duct Velocity: The velocity of air or fluid flow within the duct or pipe, usually measured in meters per second (m/s) or other relevant units.
  • Flow Rate: The volumetric or mass flow rate of the air or fluid passing through the duct.
  • Cross-sectional Area: The area of the duct’s cross-section perpendicular to the direction of flow.

This calculation is essential for designing and optimizing HVAC systems, ensuring efficient fluid transport, and maintaining proper ventilation rates in enclosed spaces.

The Duct Velocity Calculator simplifies the process of determining duct velocities, helping engineers, HVAC professionals, and experts in fluid dynamics accurately design and analyze duct systems for various applications.
