A clay layer 5 m thick has double drainage. It was consolidated under a load of 127.5 kN/m2. The load is increased to 197.5 kN/m2. The coefficient of volume compressibility is 5.79 × 10^–4 m2/Kn and value of k = 1.6 × 10^–8 m/min. If the test sample is 2 cm thick and attains 100% consolidation in 24 hours, what is the time in days taken for 100% consolidation in the actual layer? Show diagram
