Gel strength - Optimal solid removal efficiency

Input(s)

$\mathrm{V}_{\mathrm{s}}$: Expected Drilled Solids in Drilling Fluid (fraction)

$\mathrm{V}_{\mathrm{c}}$: Drilled Solids in Discard (fraction)

Output(s)

$\eta_{\mathrm{sr}}$: Optimal Solid Removal Efficiency (fraction)

Formula(s)

$$ \eta_{\mathrm{rs}}=1-\left(\frac{1-\mathrm{V}_{\mathrm{s}}}{1-\mathrm{V}_{\mathrm{s}}+\left(\frac{\mathrm{V}_{\mathrm{c}}}{\mathrm{V}_{\mathrm{s}}}\right)}\right) $$
