An introduction to density, specific gravity and specific weight – formulas with examples

## Relative density – Wikipedia

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.

We have the tools for you to measure density and specific gravity. A density meter provides a way to measure the gravity of substances. A hydrometers offer a simple, yet accurate way to measure the relative density or specific gravity of most any substance.

Specific gravity (density) The true specific gravity of PVC is about 1.4, which is comparatively heavy among plastics, as is the case for PET. This can be a disadvantage depending on the application.

The ASCA-6400 presents a new concept of analysis, consisting of high-precision Density/Specific Gravity Meter, Refractometer and newly-designed Gondola-transfer Sampler with all built in the compact chassis.

Density and Specific Gravity. The density of a substance is its weight per unit volume. The unit volume in the English system of measurement is 1 cubic foot. In the metric system it is the cubic centimeter; therefore, density is expressed in pounds per cubic foot or in grams per cubic centimeter.

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.

[MUSIC PLAYING THROUGHOUT] What does "specific gravity" mean? The specific gravity of an object is the density of that object divided by the density of water.

Gravity, in the context of fermenting alcoholic beverages, refers to the specific gravity, or relative density compared to water, of the wort or must at

## Specific gravity | physics | Britannica.com

Specific gravity: Specific gravity, ratio of the density of a substance to that of a standard substance. The usual standard of comparison for solids and liquids is water at 4 °C (39.2 °F), which has a density of 1.0 kg per litre (62.4 pounds per cubic foot).

Eagle Eye’s SG-Series Digital Hydrometers / Density Meters measure the specific gravity, density and density-related values of your sample and show the measuring results within seconds, ready for storage, printout or export to a PC (select models).

Density is defined as mass per unit volume; it has the SI unit kg·m-3 and is an absolute quantity. Specific gravity is the ratio of a material’s density with that of water at 4 °C and is therefore a relative quantity with no units.

Percent air voids is typically calculated using Gmm and Gmb in the following equation: Each time density is to be determined a measure of bulk specific gravity is made by either coring the pavement and determining bulk specific gravity on the sample or using a non-destructive testing method.

Specific Gravity Tester – Densimeter – Qualitest offers extensive range of advanced Density testing equipment such as different types of Densimeters for measuring solid and liquid specific gravity.

In my experience, specific gravity is without a doubt the single most abused and vaguely used term in woodworking terminology. Technically, specific gravity is a measure of the ratio of a wood’s density as compared to water.

Why do some objects float while others sink? One of the factors that determines this is the density of the object. The density of an object is related to another important factor called specific gravity, which will be the main focus of this lesson.

A urine specific gravity test compares the density of urine to water. This quick test can help determine how efficiently your kidneys are diluting your urine.

The Gas Specific Gravity Meter (SGM) provides a fast-response, direct measurement of gas specific gravity, molecular weight and relative density.

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.
