WebPorosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam). WebMar 9, 2024 · The differences between filter paper and normal paper can be summarized as follows. Porosity: Filter paper has a specific porosity that allows it to filter out certain particles, while normal paper does not have this property. Pore size: The pore size of filter paper is carefully controlled, while normal paper has a random distribution of pores.
