QUESTION 1

A 125 mm diameter and 210 mm high clay specimen has a moist mass of 5184g.
When it is dried, the mass becomes 4631 g. Find the degree of saturation in the
specimen,
assuming the specific gravity of the soil grains is 2.70.

Step-by-step explanation:

To find the degree of saturation of the clay specimen, we need to first calculate its volume and its dry mass.

The volume of the clay specimen can be calculated using its dimensions:

Volume = π/4 x diameter^2 x height

= π/4 x (125 mm)^2 x 210 mm

= 1640625 mm^3

= 1640.625 cm^3

Next, we can calculate the dry mass of the clay specimen:

Dry mass = Moist mass - Water mass

= 5184 g - 4631 g

= 553 g
