   en.wikipedia.org/wiki/Centrifugal_fan

   Centrifugal fans are, like axial fans, constant-volume devices, meaning that, at a constant fan speed, a centrifugal fan moves a relatively constant volume of air rather than a constant mass. This means that the air velocity in a system is fixed, but the actual mass of air flowing will vary based on the density of the air.

   Larger diameter fans can move more air than smaller fans at the same speed. A turbulent, high velocity air jet dissipates very quickly. A large column of air, however, "travels" farther than a small one due to the friction between moving air and stationary air, which occurs at the periphery of the moving column. [8]
