You can not calculate it. You can measure it or you can look at the manufacturer's curve.

As the other replies state,you can use the manufacturer's specs, that are based on set standards of air temp. density, free flow, etc. The easiest way is to just measure the air flow under the conditions that your running the fan at. That will give the most accurate CFM's

  1. Turn off Caps Lock.
  2. Obtain the serial number of the fan.
  3. Obtain the telephone number of the manufacturer of the fan.
  4. Telephone their technical helpline, and obtain a performance curve for the fan.
