specific gravity The term specific gravity, symbolized sp gr, refers to the ratio of the density of a solid or liquid to the density of water at 4 degrees Celsius. The term can also refer to the ratio of the density of a gas to the density of dry air at standard temperature and pressure, although this specification is less often used. Specific gravity is a dimensionless quantity; that is, it is not expressed in units.

- Specific gravity is defined in Webster's dictionary as the ratio of the weight or mass of a given volume of a substance to that of another substance (usually water for solids and liquids) used as a standard. Specific gravity is not expressed in units as it is purely a ratio.

Specific gravity It is the ratio of the. true density of the material (determined at a. specific temperature) to the true density of water. (at a specific temperature). The reason for expressing the temperatures is. that the density of pure, air-free water at 3.98 C. is 1.00000 g/ml.

Questions and Answers Under normal atmospheric pressure, nitrogen can exist as a liquid between the temperatures of 63 K and 77.2 K. (-346°F and -320.44°F). Below 63 K, nitrogen freezes and becomes a solid. Above 77.2 K, nitrogen boils and becomes a gas. Since it is obtained from the atmosphere, liquid nitrogen is inexpensive and is rarely refrigerated.

What is Specific Gravity? In more general terms specific gravity is the ratio of the density of a material to that of any standard substance, although usually this is water at 4 degrees Celsius or 39.2 degrees Fahrenheit. By definition, water has a density of 1 kg per litre at this temperature.

How to Calculate the Specific Gravity of a Substance 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/m3, that ratio is easy to find. For example, the density of gold is 19,300 kg/m3, so its specific gravity is the following:

- Specific Gravity of Liquids. The table below provides specific gravity ratings for common fluids. As you review the specs for our different float switches, not the specific gravity rating. To achieve bouyancy, the specific gravity of the float must be lower than the specific gravity of the fluid being measured. Water is the benchmark, with a specific gravity of 1.0.

specific gravity The relative density of a solid or liquid, usually when measured at a temperature of 20°C, compared with the maximum density of water (at 4°C). For example, the specific gravity of carbon steel is 7.8, that of lead is 11.34, and that of pure gold is 19.32. specific gravity in Culture Expand.

CONTENTS 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. The term relative density is often preferred in modern scientific usage.n SI units, the density of water is (approximately) 1000 kg / m3 or 1 g / cm3, which makes relative density calculations particularly convenient: the density of the object only needs to be divided by 1000 or 1, depending on the units.

Specific gravity Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. The reference substance is nearly always water at its densest (4°C) for liquids; for gases it is air at room temperature (21°C).

Specific gravity Specific gravity. Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

API gravity A specific gravity scale developed by the American Petroleum Institute (API) for measuring the relative density of various petroleum liquids, expressed in degrees. API gravity is gradated in degrees on a hydrometer instrument and was designed so that most values would fall between 10° and 70° API gravity. The arbitrary formula used to obtain this effect is: API gravity = (141.5/SG at 60°F) - 131.5, where SG is the specific gravity of the fluid.

- The resulting nitrogen gas is than warmed by 221 degrees Celsius, expanding an extra 3.7 times. The net expansion for liquid nitrogen is hence (174.6 x 3.7) 645.3 times the original volume when heated to room temperature. This means that 1 liter of liquid nitrogen will occupy 645.3 liters as a gas once it has all vaporized.

- The definition of Specific Gravity is usually based on the ratio of weight of a substance in air at 25 to that of the weight of an equal volume of water at the same temperature. The weight of 1 mL of water at 25 is approximately 1 g. The following equation may be used for calculations.

What is Specific Gravity? By definition, water has a density of 1 kg per litre at this temperature. The specific gravities of gases usually are compared to dry air which generally has a density of 1.29 g per litre.

What is the unit of specific gravity? Specific Gravity is a unitless number (dimensionless quantity.) It is the ratio between the density of the material of interest and a standard material (e.g. water at it's greatest density). The units cancel out leaving a numerical value only. Using gold as an example: Density of gold: 19.3 g/cm3.
