a soil sample is obtained by pushing a 16 in long tube into the side of a pit. the tube has an inside diameter of 3 in. and weighs 1.8 lb. The soil in the tube is trimmed so that its ends are flush with the ends of the tube. if the total weight of the tube and sample is 8.62 lb and the water content of the soil is 43.6 percent, what are the unit weight and dry unit weight of the sample? if the soil is saturated, what is the average specific gravity of its solid constituents?
