Finding that sweet spot involves careful engineering and testing, not to mention exacting fabrication of the fan components. The process of finding the sweet spot involves making sure the fan is accurately sized. This depends on a set of performance conditions, such as inlet density, static pressure, and volumetric flowrate, that tell us the proper width-to See more on processbarron
