Soil Mechanics-Soil Phase Relationships: Problem 01

by

The weight of a wet soil is 32 g. When this soil dries, its weight reduces to 30 g. If it is saturated, its weight increases to 40 g. If the specific gravity of the soil equals 2.65, then calculate: A) Water content, B)Void ratio, C)The degree of Saturation, D)Porosity, E)Volume of the Soil phases, F) Air content and Percentage air voids.
