How to calculate air velocity of a fan

WebChanging the speed of the fan will affect the air volume, the air pressure, the power consumed, and the acoustic noise produced by the fan. These relationships are described by what are called the "fan affinity laws". Fan Affinity Laws. The volume of air moved by the fan is proportional to the speed of the fan. CFM α RPM i.e. 3 x RPM produces ... WebJust as before, you can then use the volumetric air flow rate and the following formula to calculate the air speed: u air = Q air / (π.D 2 /4) = 0.169/ (π*0.08 2 /4) = 33.7 m/s. You can also figure out the air velocity at different portions of the pipes by using the pipe’s diameter and known air speed of a different pipe.
