Static Efficiency

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Static efficiency, abbreviated as SE, a dimensionless number, 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
