Question:
If a clay deposit undergoes an ultimate consolidation settlement of 45mm under single drainage condition, the ultimate consolidation settlement of the same clay deposit under double drainage condition will be ___
If a clay deposit undergoes an ultimate consolidation settlement of 45mm under single drainage condition, the ultimate consolidation settlement of the same clay deposit under double drainage condition will be ___
Show Hint
For consolidation settlements, remember that double drainage results in half the settlement compared to single drainage.

- 90mm
- 22.5mm
- 45mm
- 55mm
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
For double drainage, the settlement is halved compared to single drainage because the drainage occurs from both sides. Therefore, the ultimate consolidation settlement under double drainage will be half of the settlement under single drainage. Hence, the correct answer is 22.5mm.

- For a right-hand offset disc harrow, the longitudinal distance from the hitch point to the centers of the front and rear gangs are 2.5 m and 4.5 m, respectively. The resultant horizontal soil forces in longitudinal direction on the front and rear gangs are 3.0 kN and 3.5 kN, respectively; while the resultant horizontal soil forces in lateral directions are 2.5 kN and 4.0 kN, respectively. Considering the resultant soil forces acting at the centers of front and rear gangs, the amount of offset of the center of cut with respect to the hitch point is _________ m.

- To protect a wheat field from wind erosion, windbreaks of 2.7 m height are provided. The actual wind velocity at 15 m height perpendicular to the wind barrier is 9 m.s\(^{-1}\) and the minimum wind velocity at 15 m height required to move the most erodible soil fraction is 9.6 m.s\(^{-1}\). The distance of full protection from this windbreak is _________ m. (Rounded off to 2 decimal places)
- Water flows through a 90° V-notch weir having a discharge coefficient of 0.6. If the depth of water above the notch is 49 cm and the acceleration due to gravity is 9.81 m.s\(^{-2}\), the discharge over the notch is _________ m\(^3\).s\(^{-1}\) (Rounded off to 2 decimal places).
