Porosity of rock formula

5. Set up the equation to solve for porosity with volume. Now that you have the volume of your sample () and the pore volume ( ), you can add them together to get total volume ( ). It is now possible to use the equation = ( /) x 100% to find your porosity ( ). [9] 6. Do the calculations to find your sample’s porosity.

Porosity 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). There are many ways to test porosity in a substance or part, such as industrial CT scanning.
