Fan Static Pressure

A measure of pressure exerted on the fan which has to be overcome in order to move air in a particular direction.

Formula

  • \( FSP = SP_{out} - SP_{in} - VP_{in} \)
Variable Units Description
SPout Unit Pressure Inch Of Water Column Static pressure at the fan outlet
SPin Unit Pressure Inch Of Water Column Static pressure at the fan inlet
VPin Unit Pressure Inch Of Water Column Velocity pressure at the fan inlet
