In (3), R is relative permeability resistance of the reinforced sand, [K.sub.u] is permeability coefficient of the unreinforced sand (cm/s), and [K.sub.r] is permeability coefficient of the PSS reinforced sand (cm/s).
Relative permeability was quite complex and important.

Further examinations indicate that stable calculation results can be induced if the relative permeability ratio reaches [10.sup.4].
For this, we obtained graphs of the relative permeability ([P.sub.nanocomposite]/[P.sub.HDPE/LLDPE blend]) versus volume fraction of nanoclay used in each nanocomposite.
Because the relative permeability of nonferromagnetic metal particles is very close to 1, the magnetization can be ignored in static magnetic field or low frequency harmonic magnetic field.
Both the real and the imaginary parts of the relative permittivity [[epsilon].sub.r], the relative permeability [[mu].sub.r], the refractive index n and the relative impedance [[eta].sub.r] are shown in Fig.
The relative permeability [[mu].sub.r] of the coating is supposed to be a constant.
where k is the intrinsic permeability tensor, h is the vertical depth, [k.sub.rj] is the relative permeability, [[mu].sub.j] is the viscosity, and [[gamma].sub.j] is the specific weight of phase j.
where K is the permeability of the isotropic, homogeneous porous medium, [k.sub.i] and [k.sub.n] are the respective relative permeability of water and oil, and [P.sub.i] and [P.sub.n] are the respective pressure of water and oil, [[mu].sub.i] and [[mu].sub.n] are the respective viscosity of water and oil.
