Annular velocity for a given pump output
Input(s)
\(\mathrm{O}_{\mathrm{p}}\): Pump Output (bbl/min)
\(\mathrm{d}_{\mathrm{h}}\): Inner Diameter of Casing (in.)
\(\mathrm{d}_{\mathrm{p}}\): Outer Diameter of Casing (in.)
Output(s)
AV: Annular Velocity (bbl/min)
Formula(s)
\[
\mathrm{AV}=\frac{\mathrm{O}_{\mathrm{p}} * 1029.4}{\mathrm{~d}_{\mathrm{h}}^{2}-\mathrm{d}_{\mathrm{p}}^{2}}
\]
