Coefficient of consolidation Cv = k / (mv × γw), where k is permeability (m/s), mv is coefficient of volume compressibility (m²/kN), and γw is unit weight of water (9.81 kN/m³). Cv combines the soil's drainage ability (k) and compressibility (mv) to predict the rate of consolidation settlement. Higher Cv → faster consolidation (less time to reach required settlement).
