1. A 10cc sandstone block has mass of 20 grams. If the average density of sand grain is 2.5 gram/ cc then the porosity of sandstone in % will be?
(Thanks
to Achalanand)
Solution:
Volume (V)= 10cc
mass (m)= 20g
Average density of sand grain is (p)= 2.5 g/cc
What is the porosity of the sandstone is in % ?
Volume of the occupied space (V)= mass /density
= 20 / 2.5
=8 cc
Therefore,
Porous Volume = total volume of the sandstone – volume occupied by
grains
=10-8
=2 cc
Porosity = Volume of the porous medium / total porous medium
= 2/ 10
= 0.2
= 20%
