When working with ducts, you might need to convert FPM to CFM. Basically, we want to know how much airflow (measured in CFM or Cubic Feet Per Minute) we get at a certain airflow velocity (measured in FPM or Feet Per Minute). Now, the relationship between FPM and CFM is determined ...

CFM calculator to precisely determine the room cubic feet per minute (CFM) required to replace the air in your grow room, based on the fact that your grow room's air need to be renewed at least once every 5 minutes.
fpm), it also has a lower air flow rate (cubic feet per minute, cfm). So by slowing the air down, the cfm/ton goes down, too. (Let’s ignore for now that changing the air flow changes the AC capacity.)
For kitchen ventilation applications an air system consists of hood(s), duct work, and fan(s).The relationship between the air flow rate (CFM) and the pressure of an air system is expressed as an increasing exponential function.The graph below shows an example of a system curve.This curve...
Compressed air piping size requirements are directly related to the maximum airflow going through the system. Your airflow is measured in cubic feet of air per minute, or CFM. The greater your CFM, the larger your pipes will need to be to avoid excessive pressure drop. ...
The chart below can be used to estimate friction loss in air ducts. The default values are for air flow 400 cfm (680 m3/h) , duct size 8 in (200 mm) and friction loss 0.28 inH2O/100ft (2.3 Pa/m) . Download and print Air Ducts Friction Loss Diagram! Air Duct VelocityRelated...
First let's cover the AF140 Quiet Edition. As the chart shows the AF140 can deliver 67.8CFM of airflow, but they only have 0.84 mmH2O of static pressure. With 12V applied to this fan you should be turning at near 1150 RPM delivering 24 dBA worth of noise into the environment. ...
Ingersoll Rand is synonymous with high quality in the world of air compressors. This little unit delivers better than any compressor we tested in this category and the only compressor that actually produced what the manufacture spec claims (4.4cfm @ 90PSI). Hand-carry twin-stack 2-horsepower ai...
