Web• Fan static pressure, FSP, is the difference between the fan total pressure and fan velocity pressure, or FSP = FTP - FVP (10.2) = pt2 - pt1 - (pt2 - ps2) = ps2 – pt1 (10.3) The reason for defining fan velocity pressure in this way is that the kinetic energy imparted by the fan and represented by the velocity pressure at outlet has ... WebThe ideal static pressure is 0.5 inches for the lowest noise and to properly take care of the equipment. We at Fire & Ice use the term “static pressure” quite a bit when talking about ducts, filters, and other HVAC items. The wrong static pressure can strain your system and even shut it down. WebThe fan efficiency is the ratio between power transferred to airflow and the power used by the fan.
