Admin How do you find the specific gravity of clay?
The Specific Gravity is computed as the ratio of the weight in air of a given volume of soil particles at a stated temperature to the weight in air of an equal volume of distilled water at the same temperature.
What is the formula for specific gravity of soil?
The specific gravity G of the soil = (W 2 – W 1) / [ (W 4 – 1 )- (W 3 -W 2 )] The specific gravity should be calculated at a temperature of 27 o C and reported to the nearest 0.01. Specific gravity determines the heaviness or lightness of a material with reference to a standard material.
How do you calculate the specific gravity of water?
Calculate the object’s specific gravity by dividing its density by the density of water at 4 degrees Celsius. It follows that pure water has a specific gravity of 1 or close to 1 depending on temperature.
What is the SI unit of specific gravity?
It has the SI unit kg m-3 or kg/m3 and is an absolute quantity. Specific gravity is the ratio of a material’s density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m-3). It is therefore a relative quantity with no units.
How dense is clay?
Densities – pound per cubic foot and kilograms per cubic metre – for dirt and mud
| Material | Density – ρ – | |
|---|---|---|
| (lb/ft3) | (kg/m3) | |
| Clay, dry | 100 | 1600 |
| Clay, wet | 110 | 1760 |
| Gravel, dry | 105 | 1680 |
What is the specific gravity of soil?
The specific gravity of soil particles lay within the range of 2.65 to 2.85. Soils containing organic matter and porous particles may have specific gravity values below 2.0. Soils having heavy substances may have value above 3.0.
What is the specific gravity of gravel?
Gravel, Regular weighs 1 346 kg/m³ (84.02803 lb/ft³) with specific gravity of 1.346 relative to pure water.
What is the specific gravity of stone?
Assuming a natural stone has a Specific Gravity of 2.7, it means that its weight is 2.7 grams per cubic centimetre, or 2700 kg per cubic metre. The Specific Gravity of natural stones is usually around 2.5 to 3.0, depending on the density and kind of the containing material.
What is the specific gravity of a solid?
For solids, specific gravity is an important parameter. If we consider a soil mix, different particle in that mix has different specific gravity value. The specific gravity of whole mix is the average specific gravity of all solid particles present in that mix. For most of the soils, specific gravity lies in the range of 2.65 to 2.80.
