WebStatic pressure in fan systems is typically less than 2" SP, or 0.072 Psi. The amount of static pressure that the fan must overcome depends on the air velocity in the ductwork, the number of duct turns (and other resistive elements), and the duct length. WebMay 26, 2024 · The available static pressure is the pressure drop budget you have to work with when designing the ducts. We now go to the next step and design a duct system that will have a pressure drop of no more than the available static pressure. To do that, we size ducts and choose fittings using something called equivalent length.
