WebFeb 1, 2010 · Building differential static pressure commonly is measured with a sensor with two ports: a high-pressure port and a low-pressure port. Tubing extends from both ports. Commonly, low-port tubing is extended to the outside of a building, while high-port tubing is extended to an interior space. WebSystem Effect Simulator. Inlet System Effect (in wg.) Outlet System Effect (in wg.) Total System Effect (in wg.) The following Greenheck fan model and performance was used to determine the system effect values. Pressure (in wg.): Most calculations are based on AMCA Publication 201-02 (R2011). Actual results may vary.

WebMay 17, 2024 · Formula: SP2 = SP1 X (CFM2 ÷ CFM1)² or SP2 = SP1 X (RPM2 ÷ RPM1)² What it means: A 10% increase in CFM will result in a 21% increase in static pressure. Think about that. A small increase in airflow creates a significant increase in duct pressure. This increased pressure will be evenly distributed across components like coils and filters. sons of serendip sons of the american revolution france
