Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications!
Porosity is expressed as the volume not occupied by solid material
n = Vv / V
= 1 - ρbulk / ρsolid (1)
where
n = porosity
Vv = void volume (m3, ft3)
V = total volume (m3, ft3)
ρbulk = bulk density (kg/m3, slugs/ft3)
ρsolid = solid density (kg/m3, slugs/ft3)
