Determining Static Pressure - Central Blower
www.centralblower.comlength of straight duct to arrive at the total system duct length. Multiply the static pressure for 100 feet of duct by the percentage of 100 feet that you have. This will be the static pressure caused by the ductwork. Add this to the static pressure created by the hood to get the total static pressure of the system. Example:

Fans: Air Flow versus Static Pressure
www.asi.k-state.eduhave on the airflow path within a given system. For mechanical ventilation systems, the fans create positive static pressure to move air through a given system. All other components create negative static pressure that causes resistance to air moving through a system. A mechanical ventilation system operates with the static pressure in balance.
