Discussion
According to Darcy's law, the rate of flow water through soil, for laminar flow condition in a saturated soil is:
(Where, Q = rate of flow, i = hydraulic gradient, k= Darcy's coefficient of permeability
A = total cross-sectional area of soil mass perpendicular to direction of flow.)
Answer: D
Darcy's law gives Q = kiA.
For laminar flow through saturated soil, the discharge velocity is proportional to the hydraulic gradient, v = ki, where k is the coefficient of permeability. Multiplying by the total cross-sectional area of the soil perpendicular to the flow gives the rate of flow Q = kiA.
The other options square one of the three quantities, which breaks the linear proportionality on which Darcy's law rests and gives the wrong dimensions for a flow rate.
