Florida Agricultural and Mechanical University Division of Engineering Technology Spring 2015 Soil Mechanics & Foundations ETC 3211 1. The weight of a wet soil sample is 0.274 lb. The weight of the oven-dried soil is 0.211 lb. Find moisture content. w%= W/W (100%) W, -0.211 gr W₁ = ? W = 0.274 gr W = W,+W, W=W - W=0.274-0.211=0.063 lb w%= = 29.85% 2. If the weight of a dry soil sample is 38.6 gr. and the volume of the solid part of the soil is 21.2 cm3, find the specific gravity of the soil, knowing that the water density is: 1.00 gr/cm3. W=38.6 gr V=21.2 cm 0.-1 gr/cm³ = 1.82 3. The weight of a container can is 46 gr. The weight of the wet soil with the can is 214 gr. When dried in the oven, the dry soil and can weight is 186 gr. Find moisture content. 4. If the weight of a dry soil sample is 0.126 lb. and the volume of the solid part is 2.00 in3, find the specific gravity of the soil, knowing that the water density is: 62.4 lb/ft3.
