Input(s)

$\mathrm{D}_{\mathrm{L}}$: Piston Diameter (in.)

$\mathrm{L}_{\mathrm{S}}$: Stroke Length (in.)

$\mathrm{N}_{\mathrm{C}}$: Number of Cylinders (unitless)

Output(s)

$\mathrm{V}_{\mathrm{t}}$: Volume of Fluid Displaced (bbl)

Formula(s)

$$ \mathrm{V}_{\mathrm{t}}=\frac{\pi * \mathrm{D}_{\mathrm{L}}^{2} * \mathrm{~L}_{\mathrm{S}} * \mathrm{~N}_{\mathrm{C}}}{4} $$
