Fan Efficiency

on . Posted in Fluid Dynamics

Fan efficiency, abbreviated as \(\eta_f\) (Greek symbol eta), a dimensionless number, is the ratio of input and output power.


Fan Efficiency formula

\(\large{ \eta_f = \frac{ P_{out} }{ P_{in} } }\) 
Symbol English Metric
\(\large{ \eta_f }\)  (Greek symbol eta) = fan efficiency   \(\large{ dimensionless }\)
\(\large{ P_{in} }\) = input power \(\large{ W }\) \(\large{ W }\)
\(\large{ P_{out} }\) = output power \(\large{ W }\) \(\large{ W }\)
