Known the soil properties: e - void ratio, n - porosity, w - water content, G - specific gravity, S - degree of saturation, γsat - Saturated unit weight of soil; and γw - unit weight of water. From among the following relations, identify the relation that is INCORRECT.
1
γsat = \(\frac{G + e}{1 + e}\) γw
2
e = \(\frac{n}{1 - n}\)
3
n = \(\frac{e}{1 - e}\)
4
e = \(\frac{w G}{S}\)
