Annular volume capacity of pipe
Input(s)
\(\mathrm{D}_{\mathrm{h}}\): Inner Diameter of Casing against Pipe (in.)
\(\mathrm{D}_{\mathrm{o}}\): Outside Diameter of Pipe (in.)
L: Length of Pipe (ft)
Output(s)
\(\mathrm{V}_{\mathrm{a}}\): Annular Volume Capacity (bbl)
Formula(s)
\[
\mathrm{V}_{\mathrm{a}}=\frac{0.7854 *\left(\mathrm{D}_{\mathrm{h}}^{2}-\mathrm{D}_{\mathrm{o}}^{2}\right) * \mathrm{~L}}{808.5}
\]
