The space it occupied is filled by fluid having a weight w fl.This weight is supported by the surrounding fluid, and so the buoyant force must equal w fl, the weight of the fluid displaced by the object is a tribute to the genius of the Greek mathematician and inventor Archimedes (ca. 287–212 B.C.) that he stated this principle long before concepts of force were well established.

More DetailsSpecific Gravity is a measure of the density of a mineral. At times it is such a useful property that it is the only way to distinguish some minerals without laboratory or optical techniques. Gold (pictured) can easily be distinguished from "fool''s gold" by specific gravity alone, although there are many other ways.

More DetailsSpecific 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]

More DetailsBy Steven Holzner. 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 gravity is the following:

More DetailsMeasuring the voltage of a battery bank to find out the state of charge (SOC) is less reliable than measuring the specific gravity, however, if you do it right it at least gives you a quick indication. Once you have measured the voltage, you can look up the SOC using the following table. DOD. SOC. 2 volt battery. 12 volt battery. 24 volt battery.

More DetailsSpecific Gravity of Urine is a more precise measurement of urine''s overall concentration by just looking at the color of urine.. Test which is need find out the specific gravity of urine is USG(urine specific gravity test). The test is can identify the presence of solutes in a solvent. This test is for determining whether your kidney function is normal or not.

More DetailsSpecific gravity is the density of a substance divided by the density of water. The density units cancel, leaving specific gravity a unitless number. Since we often assume the density of pure water to be 1.0 g/mL, the specific gravity usually agrees closely with density. Temperature changes affect the density of

Measure its voltage with a volt meter while open-circuit, no load (general approximation). 3. Track the current flow in and out of the battery with a ''shunt'' and associated metering circuit (common with alt-energy systems).

More Details· Here''s a table of densities of common substances, including several gases, liquids, and solids. Density is a measure of the amount of mass contained in a unit of volume.The general trend is that most gases are less dense than liquids, which are in turn less dense than solids, but there are numerous exceptions. For this reason, the table lists density from lowest to highest and includes the ...
