One uses a device called a hydrometer to measure the specific gravity of liquids. There are a variety that are used for specific purposes such as: the charge of a car battery, alcoholic content of water-alcohol mixtures, freezing point of radiator fluid in a car, etc.

Specific Gravity (= Relative Density) - SG - is a dimensionless unit defined as the ratio of the density of a substance to the density of a reference substance - at a specified temperature and pressure, and can be expressed as. SG = ρ substance / ρ reference (3). where. SG = Specific Gravity of the substance. ρ substance = density of the fluid or substance [kg/m 3]

This table is a data information resource for the specific gravity of many common metals. While the data is extremely useful for design, actual individual samples will probably differ.

NTP - Normal Temperature and Pressure - defined as 20 o C (293.15 K, 68 o F) and 1 atm ( 101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr); Molecular weights can be used to calculate Specific Gravity if the densities of the gas and the air are …

specific gravity n. The ratio of the mass of a solid or liquid to the mass of an equal volume of distilled water at 4°C (39°F) or of a gas to an equal volume of air or hydrogen under prescribed conditions of temperature and pressure. Also called relative density. specific gravity n (General Physics) the ratio of the density of a substance to that of ...

The specific gravity is a unitless number that compares the density of a substance to the density of some standard substance (usually, but not always water). So to calculate the density of an object, you just multiply its specific gravity by the density of water or the density of whatever the ...

Density (specific gravity) Specific gravity is defined by ASTM D4439 (from volume 04.13 on Geosynthetics) as the ratio of the density of the substance in question to the density of a reference substance at a specified condition of temperature and pressure.

Both density and specific gravity describe mass and may be used to compare different substances. They are not, however, identical measures. Specific gravity is an expression of density in relation to the density of a standard or reference (usually water).

The standard fine aggregate specific gravity and absorption test is: AASHTO T 84 and ASTM C 128: Specific Gravity and Absorption of Fine Aggregate; Background. Specific gravity is a measure of a material's density (mass per unit volume) as compared to the density of water at 73.4°F (23°C).

Because water at 4 degrees Celsius is the standard scientists use to determine specific gravity, it follows that its specific gravity is 1. However, a water sample at a different temperature or pressure or one containing impurities has a density that differs slightly.

In physics, a substance's specific gravity is the ratio of that substance's density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m 3, that ratio is easy to find. For example, the density of gold is 19,300 kg/m 3, so its specific ...

Specific Gravity, also known as SG, is a measurement that determines the density of minerals.Two minerals may be the same size, but their weight may be very different. The specific gravity of a mineral determines how heavy it is by its relative weight to water.

Most homebrewers measure the specific gravity of their beer at the beginning of fermentation and then at the end. They then use these numbers to calculate (usually using software) what the ABV of …

Specific Gravity Test - Test Urine Analysis. Specific gravity tests for sample dilution. Urine specific gravity is a test that measures the concentration of particles in the urine.

What is Specific Gravity? The Specific Gravity of liquids and solids is defined as a dimensionless unit which is the ratio of density of a material to the density of water at a given temperature, where density is defined as the material's mass per unit volume and is measured in kg/m 3.The temperature and pressure of both the material and water need to be the same as these factors influence ...

Specific gravity is an important tool in the jewelry business. Let's imagine that Julie the Jeweler wants to make a piece with a gold ring. She buys the gold online and wants to know for sure that ...

Specific gravity is an important tool in gemstone identification that is useful for the gem buyer as well as the gemologist. A 1-carat stone with higher specific gravity will be smaller than a 1-carat stone with lower specific gravity.
