The interrelation between percentage air voids, specific gravity, dry unit weight, unit weight of water and water content is given by:
1
\(\rm \gamma_d = \frac{(1 + na)G \gamma_w}{1 + Gw}\)
2
\(\rm \gamma_d = \frac{G \gamma_w}{1 - na}\)
3
\(\rm \gamma_d = \frac{(1 - n_a)G \gamma_w}{1 + Gw}\)
4
\(\rm \gamma_d = \frac{G \gamma_w}{1 + na}\)
