Darcy's Law Calculator

Find groundwater flow rate through a porous medium.

Hydraulic conductivity

Cross-section area

Hydraulic gradient

Calculated Output

Flow rate (m³/s) 0

Formula: Q = k·A·i

Step-by-Step Breakdown

1. Values used:

2. Hydraulic conductivity = 0.0001

3. Cross-section area = 2

4. Hydraulic gradient = 0.05

6. Flow rate = Hydraulic conductivity x Cross-section area x Hydraulic gradient = 0.0001 x 2 x 0.05 = 0m³/s

Did this calculator solve your problem today?

The math behind it

Q = k·A·i, where k is hydraulic conductivity, A the area and i the hydraulic gradient.

k = 1×10⁻⁴ m/s, A = 2 m², i = 0.05 → 1×10⁻⁵ m³/s.

Where is it used?

Hydrogeology, filtration and reservoir engineering.
