Overall Efficiency

Overall Efficiency Formulas

\(\large{ \eta_o = \frac{ output\; HP \; 100 }{ input\; HP } }\)	(motor) (pump)
\(\large{ \eta_o = ME \; VE }\)	(motor) (pump)

Where:

\(\large{ \eta_o }\)  (Greek symbol eta) = overall efficiency

\(\large{ ME }\) = mechanical efficiency

\(\large{ VE }\) = volumetric efficiency
