We know that vol Of voids = vol Of air + vol Of water.
Dividing both sides with vol Of voids then we get air content + degree of Saturation = 1.
Dividing both sides with vol Of voids then we get air content + degree of Saturation = 1.

Air content = 1-Sr this should be % air voids.

@Protap.
Na percentage of air voids.
Na percentage of air voids.

This is not air content this is % air voids.

The percentage of air voids should be on LHS which is equal to porosity*air content, air content is equal to 1-S, porosity = e/1+e.

Actually here is not air content, here is air voids.
ac+Sr=1, ac=1-Sr.
Na=ac*n, n=e/1+e.
Na=e(1-Sr)/(1+e).
ac+Sr=1, ac=1-Sr.
Na=ac*n, n=e/1+e.
Na=e(1-Sr)/(1+e).

Actually, there in place of ac it should be na.
