Darcy’s Law Calculator

Calculate the volumetric flow rate using Darcy’s Law: $$ Q = K \, A \, \frac{\Delta h}{L} $$

* Enter the hydraulic conductivity $ K $ (m/s), cross-sectional area $ A $ (m²), head difference $ \Delta h $ (m), and length $ L $ (m).

Step 1: Enter Parameters

Hydraulic Conductivity, $ K $ (m/s):

e.g., 1×10⁻⁵ m/s

Cross-sectional Area, $ A $ (m²):

e.g., 0.01 m²

Head Difference, $ \Delta h $ (m):

e.g., 2 m

Length, $ L $ (m):

e.g., 10 m
