 | What Is the Specific Gravity of Water? : What Is the Specific Gravity of Water? Specific gravity is measured in comparison to the specific gravity of water, which makes water's specific gravity equal to one. Learn the equation used to determine the specific gravity of a substance with help from a math and science teacher in this free video on gravity.

 | Howto Test Fake Gold and silver Specific Gravity The coin is weighed in air then weighed in water and a ratio is calculated. Each metal has an exact specific gravity. Relative density, or specific gravity,[1][2] 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. The density of substances varies with temperature and pressure so that it is necessary to specify the temperatures and pressures at which the densities or weights were determined. It is nearly always the case that measurements are made at nominally 1 atmosphere (101.325 kPa the variations caused by changing weather patterns) but as specific gravity usually refers to highly incompressible aqueous solutions or other incompressible substances (such as petroleum products) variations in density caused by pressure are usually neglected at least where apparent specific gravity is being measured.

 | Homebrew beer, Specific gravity reading with hydrometer My awesome Carsponsors vid: www.youtube.com Video of specific gravity reading of a sample of beer from my primary fermenter. Reading was taken 5 days into fermentation. I belive the reading is 1.019 and I had an original gravity reading of 1.052. So, after 5 days thats an ABV of approx 4.32% 2007年05月22日再生回数 29012 |
