Consolidation parameters

Consolidation is the process of expulsion of pore water present in the voids of soil solids under the pressure of the applied load. This is a quick process in the case of coarse-grained soils since the permeability is high due to the presence of more voids, while it is a slow and gradual process in the case of clayey soil as the permeability of clay is less. An example of consolidation is the settlement of soil under a building due to the load coming from the building.

Question

A fully saturated clay specimen is placed in a consolidometer and subjected to a loading of
200 kN/m². After some of time, it was found that the average pore pressure in the specimen
