Calculate the time taken for 30 % consolidation in the field.

Question

The time required for 50% consolidation of a 25 mm thick layer (drained at both top and bottom) in the laboratory is 2 min 20 sec. How long in days will it take for a 3 m thick layer clay of the same clay in the field under the same pressure increment to reach 50% consolidation? In the field there is a rock layer at the bottom of the clay.
