B
50%
C
90%
D
25%
Correct Answer
B. 50%
Why is this the answer?
Terzaghi consolidation: Tv = pi/4 * (U%)^2 / 10000 for U < 60%. At U=50%: Tv = pi/4 * (50)^2 / 10000 = 0.196 approximately 0.197. At U=90%: Tv = 0.848. The time factor Tv = Cv*t/Hd^2 (Cv = coefficient of consolidation, Hd = drainage path = H/2 for doubly drained layer).
