The time rate of settlement data shown below is for the increment from 20 to 40 kPa from the test in Fig. 8.5. The initial sample height is 2.54 cm, and there are porous stones on the top and at the bottom of the sample. Determine cv by:
(a) The log time-fitting procedure
(b) The square root of time procedure.
(c) Compare the results of (a) and (b).
