Total Pump Efficiency

on . Posted in Fluid Dynamics

Total pump efficency, abbreviated as \(\eta_{tp}\) (Greek symbol eta), a dimensionless number, is the conversion of one form of energy into another form of energy.


Total Pump Efficiency formula

\(\large{ \eta_{tp} = \frac{WHP}{BHP} }\) 
Symbol English Metric
\(\large{ \eta_{tp} }\)  (Greek symbol eta) = total pump efficiency   \(\large{dimensionless}\)
\(\large{ BHP }\) = brake horsepower \(\large{\frac{ft-lbf}{sec}}\)  \(\large{\frac{Btu}{s}}\) 
\(\large{ WHP }\) = water horsepower \(\large{\frac{ft-lbf}{sec}}\)  \(\large{\frac{Btu}{s}}\)
