What is Permeability?
Permeability (k) is a measure of a material’s ability to transmit fluids. It quantifies the ease with which a fluid can flow through the interconnected pores or voids within a material. A higher permeability indicates that fluids can flow more readily through the material.
Imagine a porous rock; its permeability determines how easily oil or water can be extracted from it. In contrast, a dense, non-porous material like glass has very low permeability, preventing fluids from passing through it.
Common Units of Permeability
Permeability is expressed in various units, depending on the system of measurement and the specific application. Here are some of the most common ones:
- Square meter (m²): The SI unit of permeability, representing the ability of a material to transmit fluids when the pressure gradient is 1 Pascal per meter and the dynamic viscosity of the fluid is 1 Pascal-second.
- Darcy (D): A commonly used unit in geophysics and petroleum engineering, named after Henry Darcy, who conducted pioneering work on fluid flow through porous media. One darcy is approximately equal to 9.869233 × 10⁻¹³ m².
- Millidarcy (mD): A smaller unit, often used for expressing the permeability of rocks and soils, where permeability values are typically much lower than one darcy. One millidarcy is equal to 0.001 darcy.
- Permeability coefficient (cm²): This unit is often used in materials science and membrane technology, where permeability is measured in terms of the volume of fluid passing through a unit area of material per unit time under a specific pressure gradient.
Essential Permeability Conversions
Converting between these units is crucial for accurate calculations and comparisons, especially when working with data from different sources or across disciplines. Here are some of the most frequent permeability conversions:
- m² to Darcy: Divide by 9.869233 × 10⁻¹³ (e.g., 1 m² ≈ 1.01325 × 10¹² D).
- Darcy to m²: Multiply by 9.869233 × 10⁻¹³ (e.g., 1 D ≈ 9.869233 × 10⁻¹³ m²).
- Darcy to millidarcy: Multiply by 1000 (e.g., 1 D = 1000 mD).
- millidarcy to Darcy: Divide by 1000 (e.g., 1 mD = 0.001 D).
- m² to cm²: Multiply by 10,000 (e.g., 1 m² = 10,000 cm²).
- cm² to m²: Divide by 10,000 (e.g., 1 cm² = 0.0001 m²).
