Open-ended displacement volume of pipe

Input(s)

$D_{0}$: Outside Diameter of Pipe (in.)

$\mathrm{D}_{\mathrm{i}}$: Inside Diameter of Pipe (in.)

L: Length of Pipe (ft)

Output(s)

$\mathrm{V}_{\mathrm{o}}$: Open-ended Displacement Volume of Pipe (bbl)

Formula(s)

$$ \mathrm{V}_{\mathrm{o}}=\frac{0.7854 *\left(\mathrm{D}_{\mathrm{o}}^{2}-\mathrm{D}_{\mathrm{i}}^{2}\right) * \mathrm{~L}}{808.5} $$
