Web24. aug 2024 · The coefficient of permeability is different from the void ratio as e²/sup >/(1+e). For a given soil mass, if the void ratio is more then the value of the coefficient of permeability is higher. Based on different concepts it has been found that the permeability of soil is different as e² or e²/(1+e). WebThe dimension of permeability K a is [Length 2], and thus m 2 and μm 2 are typically used as the SI units. In petroleum engineering, Darcy (D) is often adopted as a unit of the permeability value, which is equal to 0.986,923 μm 2, and millidarcy (mD) is widely used. Permeability of petroleum reservoir rocks typically ranges from 0.1 to 1000 mD.
