# What is the use of 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.

What is the specific gravity of oil?

How do you measure the specific gravity of a liquid?

Obtain the density for the liquid in question. The density of a substance is equal to its mass divided by its volume. You can measure the mass on a scale and record the volume of the liquid used. Use the equation “m / v = D” where m is mass in grams or kilograms, v is volume in milliliters or liters, and D is density.

## What is the specific gravity of milk?

The specific gravity of milk measured at 15oC or 20oC is normally 1.028 – 1,033 kg/litre. The specific gravity depends on the protein and fat content. The specific gravity of fat is 0.93, solids-non-fat, 1.6 and water 1.0 kg/litre.

## What is the specific gravity of air?

Specific gravity of air, ammonia, butadiene, carbon dioxide, carbon monoxide and some other common gases. Since specific gravity is the ratio between the density (mass per unit volume) of an actual gas and the density of air – specific gravity has no dimension. The density of air at NTP is 1.205 kg/m3.

## What is the specific gravity of diesel?

The specific gravity of diesel fuel oil lies in the range of 0.82 to 0.95. The specific gravity of diesel fuel oil is reported at 15.6 degree centigrade.

## What is the specific gravity of the blood?

For whole blood it was found to be 1.0621 (95% confidence interval: 1.0652-1.0590) at 4 °C and 1.0506 (95% confidence interval: 1.0537-1.0475) at 37 °C. Plasma specific gravity was 1.0310 (95% confidence interval: 1.0324-1.0296) at 4 °C and 1.0205 (95% confidence interval: 1.0216-1.0193) at 37 °C. All of these values

## Is density and specific gravity the same thing?

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 scientific usage.

## Who is the inventor of specific gravity?

The discovery of specific gravity makes for an interesting story. Sometime around 250 B.C., the Greek mathematician Archimedes was given the task of determining whether a craftsman had defrauded King Heiro II of Syracuse.

## What is the meaning of specific gravity of cement?

To determine the specific gravity is normally defined as the ratio between the weight of a given volume of material and weight of an equal volume of water.To determine the specific gravity of cement, kerosene which doe snot recent with cement is used.

## What does a low specific gravity mean?

Adults generally have a specific gravity in the range of 1.010 to 1.030 Increases in specific gravity (hypersthenuria, i.e. increased concentration of solutes in the urine) may be associated with dehydration, diarrhea, emesis, excessive sweating, urinary tract/bladder infection, glucosuria, renal artery stenosis,

## What is the specific gravity and density?

Density = Mass / Volume. Specific gravity is the density of a substance divided by the density of water. Since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density (but without any units).

## What is the specific gravity of coarse aggregate?

The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the fine aggregate specific gravity test.

## What is the specific gravity of a soil?

The knowledge of specific gravity is needed in calculation of soil properties like void ratio, degree of saturation etc. DEFINITION. Specific gravity G is defined as the ratio of the weight of an equal volume of distilled water at that temperature both weights taken in air.

## What is the specific weight of water?

The specific weight (also known as the unit weight) is the weight per unit volume of a material. The symbol of specific weight is γ (the Greek letter Gamma). A commonly used value is the specific weight of water on Earth at 4°C which is 9.807 kN/m3 or 62.43 lbf/ft3.

## What are the uses of specific gravity?

The term “Specific Gravity” (SG) is used to define the weight or density of a liquid as compared to the density of an equal volume of water at a specified temperature. The temperature used for measurement is usually 39.2oF (4oC), because this temperature allows water to assume its maximum density.

## What is the specific gravity of sand?

Sand particles composed of quartz have a specific gravity ranging from 2.65 to 2.67. Inorganic clay’s generally range from 2.70 to 2.80. Soils with large amounts of organic matter or porous particles (such as diatomaceous earth) have specific gravities below 2.60. Some range as low as 2.00.

## How do you measure specific gravity?

Read the specific gravity from the hydrometer. The hydrometer is marked with different specific gravity measurements at different intervals. The reading on the hydrometer is usually a decimal, but it is derived as a ratio of the density of your liquid to the density of water at a given temperature.

## What is the specific gravity of water?

The specific gravity of an object is the ratio between the density of an object to a reference liquid. Usually, our reference liquid is water, which has a density of 1 g/mL or 1 g/cm^3.
