WebStatic pressure is used to evaluate the amount of impact various ventilation system components have 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. WebJun 24, 2024 · Static pressure is the pressure generated by the air molecules hitting the duct wall due to irregular movement. When calculating, the static pressure with absolute vacuum as the calculation zero points are called absolute static pressure. The static pressure with atmospheric pressure as the zero point is called relative static pressure.
