Volume of Fluid Displaced for a Duplex Pump Formula

\( V_{fd} \;=\;   n_c \; SL \; [\; ( 2 \; p_d^2 ) - r_d^2 \;] \; \eta_v \;/\; 42 \;\; 294 \)
Symbol English Metric
\( V_{fd} \) = volume of fluid displaced \(bbl\;/\;stroke\) -
\( n_c \) = number of cylinders \(dimensionless\) -
\( SL \) = stroke length \(in\) -
\( p_d \) = piston diameter \(in\) -
\( r_d \) = rod diameter \(in\) -
\( \eta_v \)  (Greek symbol eta) = volumetric efficiency \(dimensionless\) -

    

Volume of Fluid Displaced for a Single-acting Pump Formula

\( V_{fd} \;=\;  \pi \; p_d^2  \; SL \; n_c \;/\; 4 \)
Symbol English Metric
\( V_{fd} \) = volume of fluid displaced \(bbl\) -
\( \pi \) = Pi \(3.141 592 653 ...\) -
\( p_d \) = piston diameter \(in\) -
\( SL \) = stroke length \(in\) -
\( n_c \) = number of cylinders \(dimensionless\) -

Symbol English Metric
\( V_{fd} \) = volume of fluid displaced \(bbl\;/\;stroke\) -
\( SL \) = stroke length \(in\) -
\( p_d \) = piston diameter \(in\) -
\( \eta_v \)  (Greek symbol eta) = volumetric efficiency \(dimensionless\) -
