Question

The void ratio of clay A decreased from 0.572 to 0.505 under a change in pressure from 1.20 kPa to 1.80 kPa. The void ratio of clay B decreased from 0.612 to 0.597 under the same increment of pressure. The thickness of sample A was 1.50 times that of B. Nevertheless the time required for 50% consolidation was three times longer for sample B than for sample A. What is the ratio of the coefficient of permeability of A to that of B?
