Nettet9. mai 2024 · The first law of fans is a useful tool when working out the volumetric flow rate supplied by a fan under speed control or conversely working out what the RPM would be to deliver a required volume of air and hence what frequency to set a variable speed drive (VSD) to. Volumetric flow rate (V, m³/hr) varies directly proportional to the ratio of ...
