According to Darcy's Law, what is the correct equation?

The correct equation according to Darcy's Law is represented by the formula Q = KiA. In this context, 'Q' denotes the discharge or flow rate of fluid through a porous medium, 'K' is the hydraulic conductivity of the material, 'i' is the hydraulic gradient, and 'A' is the cross-sectional area through which the flow occurs.

Darcy's Law fundamentally describes how fluids will move through a saturated porous medium. The hydraulic gradient 'i' is defined as the change in hydraulic head (or potential energy) per unit distance in the direction of flow. By multiplying the hydraulic gradient with the hydraulic conductivity and the area, the equation effectively quantifies the volume of fluid that passes through a specified area over a certain period of time.

The other options do not accurately represent Darcy's Law. For instance, while K/A captures a different relationship, it does not account for how area influences flow rate. Similarly, the formula Q = K*(delta H/delta L) may suggest the hydraulic gradient but omits the essential factor of area necessary for calculating flow through the medium. Lastly, Q = KiL does not conform to the structure which relates flow rate, gradient, and area—thus making it an incorrect representation of
