Question

A clay soil tested in a consolidometer showed a decrease in void ratio from 0.9 to 0.8 when the pressure was increased from 0.2 to 0.45 kgf/cm². If the coefficient of consolidation (c_v) determined in the test for the given stress increment was 10 m²/year, Calculate the coefficient of permeability in cm/sec.
