How do you calculate CFM from motor kw?
If we want to calculate the CFM (Cubic Feet per Minute) for a 4 cycle motor we can multiply the cubic inch displacement of the engine by the maximum rpm (Revolutions Per Minute) and divide the result by 3456. Then we multiply the results by the volumetric efficiency of the motor.
What is CFM in an air compressor?
CFM is an acronym for Cubic Feet per Minute. CFM measures the volume of air, in cubic feet, for each minute it moves. In the case of an air compressor, CFM indicates how much air can move per minute. For example, an air compressor’s output rated for 30 CFM means 30 cubic feet of air is flowing per minute.

Is it better to have a higher CFM?
A higher CFM is always better for your kitchen fan. You can always run a high CFM hood on lower settings. It provides great ventilation by moving a heavy amount of air per minute.
How much CFM is enough?
Simply put, the higher the CFM, the more air the hood vents out of your kitchen. To power your range hood, you need at least 100 CFM for every 10,000 BTUs of your stovetop. For example, a 100,000 BTU stove needs at least a 1000 CFM range hood. For electric stoves, multiply the stove width by 10.
