Undisturbed soil sample was collected from the field in steel Shelby tubes for laboratory evaluation. The tube sample has a diameter of 71 mm, length of 558 mm, and a moist weight of 42.5 × 10-3 kN. If the oven-dried weight was 37.85 × 10-3 kN, and Gs × 2.69, calculate the following:
a. Moist unit weight
b. Field moisture content
c. Dry unit weight
d. Void ratio
e. Degree of saturation
