Total External Static Pressure (TESP): A Basic Review
WebJan 15, 2013 · The higher the static pressure, the lower the air flow. The two rating points are 0.1 inch water column (w.c.) and 0.25 inch w.c. In Pascals (Pa), those points are 25 Pa and 62.5 Pa. Properly designed and installed systems should be able to keep the static pressure below 0.25 inch w.c. Webi.e. Constant static pressure, velocity pressure and potential pressure. i.e. No change of static pressure, velocity pressure and potential pressure.
