What is saturated unit weight of soil?
The saturated unit weight of soil is the weight of soil per unit volume when all pore spaces are filled with water. It is commonly used in geotechnical engineering to characterize the density of saturated soil samples during testing.
PROBLEM EA Sample of moist soil has a water content of 20.0% and the moist unit weight of 21.09 KN/cu.meter. The specific gravity of the soil is 2.75. Compute the degree of saturation and the value of porosity?

What is the unit weight of clay soil?
The unit weight of clay soil typically ranges from 95 to 120 pounds per cubic foot (pcf) or 1520 to 1920 kilograms per cubic meter (kg/m^3) depending on its moisture content and composition.
Are specific gravity and density the same when discussing the physical properties of a substance?
No, specific gravity and density are not the same when discussing the physical properties of a substance. Density is the mass of a substance per unit volume, while specific gravity is the ratio of the density of a substance to the density of a reference substance, usually water.
Define properties of soil soil elements?
soil properties basically is the void ratio, porosity, specific gravity, dry unit weight, saturated unit weight, liquid limit, plastic limit and shrinkage limit which play a important role to support load.
Importance of specific gravity of soil?
The Specific Gravity (Gs) is needed for various calculations purposes in Soil Mechanics, e.g. void ratio, density, and unit weight. For Sandy soil, i.e. soils mostly made of quartz, Gs can be accurately estimated to be about 2.65, whereas for silty and clayey soils, it may vary from 2.6 to 2.9.

What is the difference between specific gravity and density?
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
What is saturated unit weight of soil?
The saturated unit weight of soil is the weight of soil per unit volume when all pore spaces are filled with water. It is commonly used in geotechnical engineering to characterize the density of saturated soil samples during testing.
Does specific gravity has units?
- The specific weight is the weight of a known volume of material at a given temperature and pressure; the unit of measure is kN/m3. - But if you think to relative density: Relative density (specific gravity) is the ratio between the density of the material to be tested and the density of water, at a given temperature and pressure; consequently no unit of measure for this ratio.
PROBLEM FA sample of soft saturated clay weighs 350 grams and has a volume of 205cc. After oven drying, the soil weighs 225 grams. Calculate the values of saturated unit weight, void ratio, porosity and specific gravity?

Why specific gravity increases in case of skimmed milk?
The specific gravity of skimmed milk is greater than that of whole milk because because cream is lighter than milk, thus removing it makes the remaining liquid heavier per unit of volume. As a liquid's weight per unit of volume increases its specific gravity increases.
Specific weight of liquids?
Specific weight is a measure of the weight per unit volume of a substance. For liquids, specific weight is typically expressed in units like pounds per cubic foot or newtons per cubic meter. It is calculated by dividing the weight of the liquid by its volume.
What is the basic SI unit of weight?
The Newton - weight is measured in force. mass*gravity = weight mass (kg) gravity (m/s^2) weight in (N)
Metric unit for measuring weight?
The SI unit for measuring weight (the force due to gravity) is the newton.The SI unit for measuring mass is the kilogram.
What is the specific gravity and its unit?
Specific gravity doesn't have units. It's the density relative to water, so specific gravity is effectively just a number.
