Permeability is a measure of the ease with which a fluid can flow through a porous mediumit is the inverse of resistance to flow the permeability of a sample is, therefore, determined by measuring the rate at which a liquid will flow through a porous medium of specific dimensions with a given. Permeability is the property of rocks that is an indication of the ability for fluids (gas or liquid) to flow through rocks the proportionality constant specifically for the flow of water through a porous media is called the hydraulic conductivity permeability is a portion of this. Permeability is a measure of the porous media's ability to allow fluids (gas or liquid) to flow through it the higher the permeability of the porous media, the faster fluids can move through it.
