The degree of consolidation for a soil mass is less than 60%, the coefficient of consolidation is Cv, and 'd' is the length of the drainage path (single drainage). What will be degree of consolidation (U) after a time 't'?
1
(2 × d) × (Cv/πt)1/2
2
(2/d) × (Cv × t/π)1/2
3
(2/d) × (Cv/π t)1/2
4
(2 × d) × (Cv × t/π)1/2
