Geotech- Relation between Void Ratio and Porosity / Derivation of Void ratio and Porosity

In this video i have derive the relation between void ratio and porosity in a very simple way.

Terms used:-
e - void ratio
n- porosity
Vv- volume of void
Vs- volume of solids
Vt- total volume
s - degree of saturation
w- water content
G- specific gravity
r- gamma bulk
r(sat.)- gamma saturated
rd- gamma dry
r'- gamma submerged
