Mmetụta na Permeability
Mbelata Permeability ọnụọgụ
Mgbakwunye fiber na-egbochi obere oghere, na-ebelata ikike. Dịka ọmụmaatụ, ịba ụba ọdịnaya fiber site na 0.05% ruo 0.2% ji nwayọọ nwayọọ na-ebelata ọnụọgụ nke permeability, ma ọ ka na-ezute nkọwapụta (dịka ọmụmaatụ, permeability> 1 mm/s na 20% porosity).
