Undisturbed soil sample 30 mm thick got 50% consolidated in 20 minutes with drainage allowed at top and bottom in the laboratory. If the clay layer from which the sample was obtained is 3 m thick in field conditions, estimate the time it will take to consolidate 50% with (i) double surface drainage (ii) single surface drainage if in both cases consolidation pressure is uniform.
