Question: A doubly drained specimen, 2.54 cm in height, is consolidated in the lab under an applied stress. The time for 50% overall (or average) consolidation

A doubly drained specimen, 2.54 cm in height, is consolidated in the lab under an applied stress. The time for 50% overall (or average) consolidation is 12 min.
(a) Compute the cv value for the lab specimen.
(b) How long will it take for the specimen to consolidate to an average consolidation of 50%?
(c) If the final consolidation settlement of the specimen is expected to be 0.43 cm, how long will it take for 0.18 cm of settlement to occur?
(d) After 14 minutes, what percent consolidation has occurred at the middle of the specimen?
