Linear annular capacity of pipe
Input(s)
\(\mathrm{D}_{\mathrm{h}}\): Inside Diameter of Casing Against the Pipe (in.)
\(\mathrm{D}_{\mathrm{o}}\): Outside Diameter of Pipe (in.)
Output(s)
\(\mathrm{C}_{\mathrm{o}}\): Annular Linear Capacity of Pipe \((\mathrm{bbl} / \mathrm{ft})\)
Formula(s)
\[
\mathrm{C}_{\mathrm{o}}=\frac{0.7854 *\left(\left(\left(\mathrm{D}_{\mathrm{h}}\right)^{2}\right)-\left(\left(\mathrm{D}_{\mathrm{o}}\right)^{2}\right)\right)}{808.5}
\]
