Density specific gravity 違い
WebDec 19, 2024 · Specific gravity (SG) is defined as the ratio of the mass of an object in the air compared with the mass of an equal volume of water. Specific gravity = mass of object in air/mass of the equal volume of water But it can also be written: specific gravity = weight of an object in air/weight of the equal volume of water WebSep 2, 2016 · Specific gravity is sometimes referred to as liquid density Specific gravity is expressed as a ratio where water is assigned the value of 1 Materials that have a specific gravity greater than 1 (material specific gravity >1) will be heavier than water and will sink to the bottom of the water column
