Cfm to lfm

This calculator requires the use of Javascript enabled and capable browsers. This script calculates a flow rate of linear feet per minute from cubic feet per minute. Thermal Resistance Calculator – Round Pin Heat Sink . Volume flow is usually measured in Cubic Feet per Minute (CFM).


Concept of Air Velocity can be used in air. CFM to LFM Calculation - Download as PDF File (.pdf), Text File (.txt) or read online. Air velocity is calculated by dividing the volumetric flow rate by the cross-sectional area of the air flow passage. Velocity (LFM) = Volume (CFM) area (ft²).


LFM is apparently equivalent to CFM divided by the cross-sectional area of interest. The larger the cross-sectional area, the smaller the LFM for . The air flow conversion calculator can be used to convert between common units for CFM and LFM flowing past a point in a specified area of duct. Most fans are rated in CFM or Cubic Feet per Minute of air “Volume” flow. So, what size fan do you need to provide 2LFM of air “Velocity” .
