Table 2

The relative error (its mean value and standard deviation (std)) for all estimates for homogeneous and nonhomogeneous porous medium.

Relative error of estimate
Homogeneous case:
Mean	0.05%	4.04%	3.08%	3.35%	2.00%
std	0.07%	0.73%	0.72%	0.76%	0.45%
Nonhomogeneous case:
Mean	4.99%	3.91%	3.03%	3.21%	1.70%
std	1.11%	1.85%	1.72%	1.78%	0.42%
