Answer (1 of 2): Since the specific gravity of a material is the ratio of its density to the density of water, the specific gravity of water, by definition is 1, no matter where you are. or. THEORY: Information regarding specific gravity of aggregate is necessary for design of concrete mixes. If there were no substances present, the specific gravity of the urine would be 1 (the same as pure water). What is the Specific Gravity in a water solution with 500 grams of sugar dissolved in 1 liter of water? They are equipped with drain and overflow outlets. Since water has a specific gravity of 1 at sea level, liquids and substances with a specific gravity lower than 1 will float in water. Specific gravity (also known as "relative density") is the ratio between the weight of a stone in air and the weight of an equal volume in water. The specific gravity of salt water is about 1.025 or so. Specific Gravity is the density difference between one substance and the density of a different substance used as a benchmark. where, density of water is taken as 999 kg/m 3. Specific gravity (SG) for water is given for four different reference temperatures (4, 15, 15.6 and 20°C). Water is the benchmark for liquids and solids, while hydrogen or "air" being the measurement for gases. These ions are different salts, minerals and/or elements. Standard guidelines are varied, but most saltwater aquarists have it at somewhere between 1.020 and 1.025 depending on if its a reef tank or a FOWLR (fish only with live rock). So the specific gravity of gold is 19.3. For example, the specific gravity of barite is 4.2 and its density is equal to (4.2) (8.33 lb/gal) = 35 lb/gal.
