What is specific density means?
n. (Units) the ratio of the density of a substance to the density of a standard substance under specified conditions. For liquids and solids the standard is usually water at 4°C or some other specified temperature.
How do you find the specific density?
Remember, finding the density involves dividing the mass by the volume. If the mass is 36 grams and the volume is 3 mililiters, then the density of the object is 12 grams per milliliter. That means that the specific gravity will be 12. That’s greater than one.
What is specific gravity Wikipedia?
Specific Gravity (SG) is a special case of relative density. It is defined as the ratio of the density of a given substance, to the density of water (H2O). Substances with a specific gravity greater than 1 are heavier than water, and those with a specific gravity of less than 1 are lighter than water.
What does SG stand for physics?
specific gravity
specific gravity, also called relative density, ratio of the density of a substance to that of a standard substance.
What is difference between specific gravity and density?
Density is defined as mass per unit volume. 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.
Why specific gravity is important?
Significance and Use 4.1 Specific gravity is an important property of fluids being related to density and viscosity. Knowing the specific gravity will allow determination of a fluid’s characteristics compared to a standard, usually water, at a specified temperature.
How do you find density from specific weight?
Knowing the specific weight, you can easily compute the weight of any amount (volume) of a substance. Multiply the specific gravity by 1,000 to calculate the density of the substance in kilograms per cubic meter (kg/cubic meters) units.
Is specific weight and density the same?
The density of the material is defined as mass per unit volume, typically measured in kg/m3. The standard gravity is acceleration due to gravity, usually given in m/s2, and on Earth usually taken as 9.81 m/s2. Unlike density, specific weight is not a fixed property of a material.
Why is specific gravity used instead of density?
What does specific gravity in urine indicate?
A urine specific gravity test compares the density of urine to the density of water. This quick test can help determine how well your kidneys are diluting your urine. Urine that’s too concentrated could mean that your kidneys aren’t functioning properly or that you aren’t drinking enough water.
