The dial gauge readings (measuring the sample deformation) for one loading stage of consolidation test are shown below. The sample is double drained during the test (with porous stones on both sides of the sample), the initial sample thickness before this loading is 24.8 mm, calculate the coefficient consolidation of the sample, Cv? (unit: mm2/min)
