Why is it important to know how to calculate air flow for HVAC? Well, if you have too much air volume flowing past the system, you may notice more humidity in your space. In the context of your heating and cooling system, using the right pipe air flow calculation formula will help guarantee that your system runs effectively. What Is Air Flow Rate?Īir flow, or airflow, at its most basic definition, refers to the movement of air, and the more distance it travels, the higher its rate. Sound complicated? Let's break down the basics of air flow speed calculation. Then, our air volume calculator will do the work and display your results below. Ready to use our CFM air flow velocity calculator? To calculate, enter the value, select the air velocity units that you prefer, and hit calculate.

This measurement is typically represented in CFM, but with an airflow calculation conversion, you can find a CMH air flow velocity calculation, which measures the airflow per hour instead of per minute. With this, you'll find the air volume that flows past the duct in terms of units per time. By using an air velocity through duct calculator, you're multiplying the air velocity by the area of a duct. Air velocity is the distance traveled per minute and is used as a measurement of the displacement rate for air and gas.Īn air velocity calculator will express this distance in LFM (ft/min, linear feet per minute). Online Duct Airflow Calculatorįor an air flow pressure calculator, we need to look at air velocity. Then hit “calculate”, and our air flow rate calculator will do the rest. To use the air flow calculator, you simply need the volume air flow or air velocity (measured in ft/sec, ft/min, miles/hr (mph), or any other common units), the duct type or area (whether it's a rectangle duct or a circular duct), and the units you're using to measure. With this calculator, we make it easy to learn how to calculate air flow in CFM (cubic feet per minute) with a convenient duct volume air flow calculator. Wondering how to calculate air velocity for your air compressor to work properly? Blackhawk Supply offers a convenient air velocity calculator online, allowing you to convert the various units for air volume flow and air velocity flowing through your system.
