Duplex pump output by using liner and rod diameters
Input(s)
\(d_{1}\): Liner Diameter (in.)
\(d_{\mathrm{r}}\): Rod Diameter (in.)
\(1_{s}\): Stroke Length (in.)
Output(s)
\(\mathrm{q}_{\mathrm{o}}:\) Pump Output (bbl/stroke)
Formula(s)
\[
\mathrm{q}_{\mathrm{o}}=0.000162 * 1_{\mathrm{s}} *\left(\left(2 *\left(\mathrm{~d}_{\mathrm{l}}^{2}\right)\right)-\left(\mathrm{d}_{\mathrm{r}}^{2}\right)\right)
\]
