Chromatographic lag in polymer flooding

Input(s)

A: Adsorption Rate (g polymer/g rock)

$\rho$: Rock Density $(\mathrm{g} / \mathrm{cc})$

$\emptyset$: Porosity (fraction)

C: Polymer Concentration $(\mathrm{g} / \mathrm{cc})$

$S_{w}$: Water Saturation (fraction)

Output(s)

CL: Chromatographic Lag (dimensionless)

Formula(s)

$$ \mathrm{CL}=\frac{1}{1+\frac{\mathrm{A} * \rho *(1-\emptyset)}{\mathrm{C} * \emptyset * \mathrm{~S}_{\mathrm{w}}}} $$
