Final answer:
The saturated unit weight of the soil sample is approximately 0.021 lbs/in³.
Explanation:
To determine the saturated unit weight of the soil sample, we need to calculate the volume of the soil sample first. The volume can be calculated using the formula for the volume of a cylinder: Volume = π * (radius)^2 * height.
Given that the diameter of the sampler is 6 inches, the radius can be calculated as half of the diameter, which is 3 inches. The height of the sampler is given as 18 inches.
Substituting the values into the formula, we get:
Volume = π * (3 inches)^2 * 18 inches = 162π cubic inches.
Next, we can calculate the saturated unit weight using the formula:
Saturated unit weight = (Moist mass - Dry mass) / Volume.
Substituting the given values, we get:
Saturated unit weight = (35.9 lbs - 32.5 lbs) / (162π cubic inches).
Using the value of π as approximately 3.14159, we can calculate the saturated unit weight:
Saturated unit weight ≈ 0.021 lbs/in³.
