sci.NAPL-dissolution-Raoult Calculator
Calculates dissolved phase concentration of a non-aqueous phase liquid (NAPL) using Raoult's law and effective solubility in contaminated groundwater. Effective solubility = mole fraction × pure phase solubility — benzene at 10% mole fraction in petroleum dissolves to ~170 mg/L (vs 1,780 mg/L pure).
Inputs
Mole Frac
Reference formula or conversion factor shown for context.
Cs Mg L
Reference formula or conversion factor shown for context.
Ksw
Reference formula or conversion factor shown for context.
Rho Bulk Kg L
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
Results
dissolved concentration Caq (mg/L)
The proportional relationship between two quantities.
sorbed concentration (mg/kg soil)
The proportional relationship between two quantities.
retardation factor R
A dimensionless multiplier applied in the calculation.
Raoult: Caq = x × Cs
Reference formula or conversion factor shown for context.
R = 1 + Ksw·ρ_bulk / n_por
Sample size or count used in the calculation.
