How to use the permeability from hydraulic conductivity calculator
Convert hydraulic conductivity of a soil or rock into intrinsic permeability. Enter hydraulic conductivity, fluid dynamic viscosity, fluid density in the fields above; the intrinsic permeability are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “permeability from conductivity”, “intrinsic permeability”, “darcy units”, “calculate permeability from hydraulic conductivity”, “find intrinsic permeability”.
Formula
Variables
- K — Hydraulic conductivity (m/s)
- mu — Fluid dynamic viscosity (Pa·s)
- rho — Fluid density (kg/m³)
Worked example
With hydraulic conductivity = 0.0001 m/s, fluid dynamic viscosity = 0.001 Pa·s, fluid density = 1000 kg/m³, the calculator gives intrinsic permeability ≈ 1.0197 × 10⁻¹¹ m²; intrinsic permeability ≈ 10.33252 darcy.
Frequently asked questions
What is the permeability from hydraulic conductivity calculator used for?
Convert hydraulic conductivity of a soil or rock into intrinsic permeability. It helps with questions such as “permeability from conductivity”, “intrinsic permeability”, “darcy units”.
What is the formula for the permeability from hydraulic conductivity calculation?
Intrinsic permeability (m²) = K × mu / (rho × GRAV). Intrinsic permeability (darcy) = [Intrinsic permeability] / 9.869e-13. Here K is hydraulic conductivity (m/s), mu is fluid dynamic viscosity (Pa·s), rho is fluid density (kg/m³).
What inputs do I need for the permeability from hydraulic conductivity calculator?
You need hydraulic conductivity in m/s, fluid dynamic viscosity in Pa·s, fluid density in kg/m³. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the permeability from hydraulic conductivity calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the permeability from hydraulic conductivity result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
