Homework Answers
volume of the moist soil includes the volume of the dry soil plus the volume of the water present in it.
weight of moist soil is the weight of the soil plus the water present in its pores.
weight of dry soil is only the weight of the solid particles of the material. this can be achieved by heating the rock so that all the water gets evapourated from pores leaving behind only the rock solid material.
hence to calculate the dry unit weight we will have to consider the dry weight of the soil not the moist soil.
Dry unit weight = Weight of soil solids/ total volume of soil
11.5/0.085= 135.3
