The result is clear. For a 1,000 sq ft room with an 8 ft ceiling and 4 ACH, you need a fan capable of delivering 533 CFM airflow. Let’s use the CFM calculation formula to see if we get the same number (this is the very formula used in the calculator): ...
The cubic feet per minute (CFM) of a gas describes its volumetric flow rate through a pipe or vent. The volumetric flow is a good measure of how much gas goes through the system, but it isn't the clearest way of picturing how quickly it moves. To picture this speed, calculate the li...
Determine the rate of flow through a given duct or pipe. This is typically measured in feet per minute--or more conventionally as ACFM (Actual Cubic Feet per Minute). Calculating ACFM requires having accurate measurements for pressure, temperature and humidity of current air conditions. It is ...
