Slurry density for cementing calculations

Input(s)

$\mathrm{V}_{\mathrm{s}}$: Volume of Slurry (gal/stroke)

$\mathrm{W}_{\mathrm{a}}$: Weight of Additive Per Sack (lb/stroke)

$\mathrm{Q}_{\mathrm{w}}$: Total Water Requirement (gal/stroke)

Output(s)

$\sigma_{\mathrm{s}}$: Slurry Density (lb/gal)

Formula(s)

$$ \sigma_{\mathrm{s}}=\frac{94+\mathrm{W}_{\mathrm{a}}+\left(8.33 * \mathrm{Q}_{\mathrm{w}}\right)}{\mathrm{V}_{\mathrm{s}}} $$
