B. Flow of water through pipe
C. Sedimentation of soil particles in water
List-II
1. Boussinesq's equation
2. Darcy's law
3. Poiseuille's equation
4. Skempton's equation
5. Stoke's law
Codes:
A B C

• A. 2 4 5
• B. 2 3 5
• C. 1 3 5
• D. 2 3 4

Answer 1

The correct option is B 2 3 5

(b)
Darcy's law states that there is a linear relationship between flow velocity (v) and hydraulic gradient (i) for any given saturated soil under steady laminar flow conditions
Stoke's Law - Sedimentation of soil particles in water with a constant velocity is known as terminal velocity. It is applicable to spheres of diameter between 0.2 mm and 0.0002 mm.
Poiseuille's equation relates pressure drop between two points to the discharge in a pipe flow system.
