Darcys Law is valid for A turbulent flow incompressible soil

Darcy\'s Law is valid for A. turbulent flow, incompressible soil skeleton, and S-100%. C B. laminar flow, compressible soil keleton, and e> 0.5. C. laminar flow, incompressible soil skeleton, and S-100%. D, transient flow, compressible soil skeleton, and n. 100%. E. none of the above C

Solution

Assumptions of darcy \'s law ..

1 soil should be fully saturated tht means degree of saturation (S)=100%

2 complete cross section of soil mass is considered

3 flow is steady and laminar .

4. He didn\'t say directly soil mass is incmpressible but it has to be tht otherwise velocity of flow will change due to change in structure voids.

Best answer is C
