Ir velocity's
WebAir velocity is measured by sensing the pressure that is produced through the movement of the air. Velocity is also related to air density with assumed constants of 70° F and 29.92 in Hg. The two most common technologies to measure velocity are capacitive based pressure sensors and hot-wire anemometers. Web0. You can calculate air velocity as v = f/A where f=volumetric air flow and A = cross-sectional area of the air passage. Also, you have m=p*f, where m=mass flow rate and p=air density. Here 1 it says that "By conservation of energy, the energy consumed in rotating the fan is the same as the energy required to deliver the air: Pfan ∝ υ".

It can be written as: R = V/I. Where: R - resistance. V - voltage. I …
WebThe British Compressed Air Society (BCAS) suggests that a velocity of 6m/s or less prevents carrying moisture and debris past drain legs and into controls. A velocity greater than 9m/s is enough to transport any water and debris in the air stream. Thus, the recommended design pipeline velocity for interconnecting piping and main headers is 6-7m ...
