A 12 m thick layer of Chicago clay is doubly drained. This means that a very previous layer compared to the clay exists on top of and under the 12 m clay layer. The coefficient of consolidation of the clay is cv = 8.0 x 10-8 m2/s. Find the degree or percent consolidation for the clay 5 years after loading at depths of 3, 6, 9, and 12 m.
