Void Ratio

Written by Jerry Ratzlaff on . Posted in Fluid Mechanics

Void ratio of a materials porosity is the ratio between void volume and solid material volume.

formula

\(e = \frac {V_v} {V_s } \)

Where:

\(e \) = void ratio

\(V_v \) = voids volume

\(V_s \) = solids volume

Solve for:

\(V_v = e   V_s \)

\(V_s = \frac { V_v} { e}   \)
