Question

define Darcy law............... With full description.

Answer 1

Darcy law:-
• This is defined as basic law which governs the fluid flow through porous media.

• This law is only valid for slow laminar flow attributes of ground water movement through most earth materials.

• This law is described as flow rate per unit time has direct proportionality with hydraulic flow gradient which is laminar through saturated mass of soil.

According to darcy equation ,
V= q/A is defined as the rate flow through the area (a) of the cross section.
Where,
K => permeability
V => velocity (or) darcian velocity (or) superficial velocity.

Answer 2

the velocity of flow of a liquid through a porous medium due to difference in pressure is proportional to pressure gradient in the direction of flow ...
