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)
\[
\mathrm{Q}_{\mathrm{e}}=7.12 * \mathrm{D} * \mathrm{E} * \mathrm{P}_{\mathrm{s}} * \mathrm{~N}-\mathrm{Q}_{\mathrm{s}}
\]
