QUESTION #2337
Question 1
According to Darcy's law, the seepage quantity \(Q\) through a soil sample of cross-sectional area \(A\), length \(L\), head difference \(\Delta h\) and permeability \(k\) is:
Correct Answer Explanation
Darcy's law: \(Q = k \cdot i \cdot A\) where the hydraulic gradient \(i = \dfrac{\Delta h}{L}\). Therefore \(Q = k \cdot \dfrac{\Delta h}{L} \cdot A\). This linear relationship is valid for laminar flow where velocity is directly proportional to hydraulic gradient.
