A 10 m thick clay layer is resting over a 3 m thick sand layer and is submerged. A fill of 2 m thick sand with unit weight of 20 kN/m³ is placed above the clay layer to accelerate the rate of consolidation of the clay layer. Coefficient of consolidation of clay is 9x10 m/year and coefficient of volume compressibility of clay is 2.2x104 m²/kN. Assume Taylor's
