Formula 2.182
Pump flow rate
Input(s)
D: Rotor Diameter (in.)
E: Rotor/Stator Eccentricity (in.)
$\mathrm{N}$: Rotary Speed $(\mathrm{rpm})$
$\mathrm{Q}_{\mathrm{s}}$: Leak Rate $(\mathrm{bbl} / \mathrm{d})$
$\mathrm{P}_{\mathrm{s}}$: Pitch Length of Stator $(\mathrm{ft})$
Output(s)
$\mathrm{Q}_{\mathrm{e}}$: Pump Flow Rate $(\mathrm{bbl} / \mathrm{d})$
Formula(s)
$$ \mathrm{Q}_{\mathrm{e}}=7.12 * \mathrm{D} * \mathrm{E} * \mathrm{P}_{\mathrm{s}} * \mathrm{~N}-\mathrm{Q}_{\mathrm{s}} $$
