### Preform surface-Porosity and permeability Moldflow

Preform porosity. Porosity represents the packing density of the preform in the cavity. Porosity is defined as the ratio of the void volume to the cavity volume before the cavity is filled with resin. The void volume is equal to the cavity volume minus the volume occupied by the fiber reinforcement.

### How to Calculate Void RatioProjectEngineer

Dec 16 2013 · The void ratio is the ratio of the volume of voids (open spaces i.e. air and water) in a soil to volume of solids.. Where e = Void Ratio V v = Volume of voids (m 3 or ft 3) V s = Volume of solids (m 3 or ft 3) V g = Volume of air (m 3 or ft 3) V w = Volume of water (m 3 or ft 3). The void ratio is thus a ratio which can be greater than 1. It can also be expressed as a fraction.

### Understanding porosity and density

Porosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage. For most rocks porosity varies from less than 1 to 40 .

### Porosity Fundamentals of Fluid Flow in Porous Media
