Two clay specimens A and B, of thickness 2cm and 3cm, have equilibrium voids rations 0.68 and 0.72 respectively under a pressure of 200 kN/m². If the equilibrium voids ratios of the two soils reduced to 0.50 and 0.62 respectively, when the pressure was increased to 400 kN/m², find the ratio of the coefficients of permeability of the two specimens. The time required by the specimen A to reach 40 percent degree of consolidation is % of that required by specimen B for reaching 40% degree of consolidation?

Question
Two clay specimens A and B, of thickness 2cm and 3cm, have equilibrium voids rations 0.68
and 0.72 respectively under a pressure of 200 kN/m². If the equilibrium voids ratios of the
two soils reduced to 0.50 and 0.62 respectively, when the pressure was increased to 400
kN/m2, find the ratio of the coefficients of permeability of the two specimens. The time
required by the specimen A to reach 40 percent degree of consolidation is 14 of that required
by specimen B for reaching 40% degree of consolidation?
