Static Efficiency

Static efficiency, abbreviated as SE, is a measure of an air mover's efficiency based on its air horsepower in terms of flow and static pressure vs. required shaft input power.

 

Static Efficiency formula

\(\large{ SE = \frac{ static HP_o }{ HP_i } }\)

Where:

\(\large{ SE }\) = static efficiency

\(\large{ HP_i }\) = horsepower input

\(\large{ HP_o }\) = static horsepower output
