An 8 m thick saturated clay lies above a permeable dense sand layer. The clay settles by 40 mm in 2 years when subjected to a widespread load of 50 kN/m2 at its surface. (Assume water table is below the dense sand layer and will not influence the settlement.) Following are the properties of clay: Bulk unit weight is 18 kN/m3, coefficient of consolidation is 1 m2/yr and specific gravity, G = 2.65, Unit weight of water= 9.81 kN/m3). Then Ultimate settlement of the clay is _____ cm
