14.
Which of the following methods is more suitable for the determination of permeability of clayey soil ?

15.
If the water content of a fully saturated soil mass is 100%, then the voids ratio of the sample is

18.
A cylindrical specimen of saturated soil failed under an axial vertical stress of 100 kN/m2 when it was laterally un-confmed. The failure plane was inclined to the horizontal plane at an angle of 45°. The values of cohesion and angle of internal friction for the soil are respectively
