Soil porosity refers to the space between soil particles, which consists of various amounts of water and air Permeability refers to the movement of air and water through the soil, which is important because it affects the supply of root-zone air, moisture, and nutrients available for plant uptake
In SI units, permeability is measured in henries per meter (H/m), or equivalently in newtons per ampere squared (N⋅A −2) The permeability constant μ 0, also known as the magnetic constant or the permeability of free space, is a measure of the amount of resistance encountered when forming a magnetic field in a classical vacuum
Permeability is a property of foundry sand with respect to how well the sand can vent, ie how well gases pass through the sand And in other words, permeability is the property by which we can know the ability of material to transmit fluid/gas The permeability is commonly tested to see if it is correct for the casting conditions
