specific weight = weight/volume就是比重，单位是 （N/m^3或者 lb/ft^3）而gravity 指的是地心引力，所以不是用力来算的，而是用密度，所以，specific gravity=density /density of water @4 摄氏度，可翻译为相对密度，，没有单位（无量纲）。
What is the specific gravity of a substance and the specific gravity of water? Understand the formula and significance of the specific gravity of...
Since Specific Gravity - SG - is dimensionless, it has the same value in the SI system and the imperial English system (BG). SG of a fluid has the same numerical value as its density expressed ing/mLorMg/m3. Water is normally also used as reference when calculating the specific gravity ...
Buoyancy (the ability of an object to float in water or air) is intimately related to specific gravity. If a substance has specific gravity less than that of a fluid, it will float on that fluid: helium-filled balloons will rise in air, oil will form a slick on water, and lead will...

Let's practice by finding the specific gravity of ice, which has a density of 916.7 kg/m3916.7 kg/m3 (57.23 lb/ft357.23 lb/ft3). To do that, we use the specific gravity formula: icespecific gravity = 916.71000=0.9167icespecific gravity=1000916.7=0.9167 And that's how to cal...
Specific gravity is a concept that we all have seen but do not know its name. Also, the density of the object determines this factor. Moreover, in thi9s topic we will discuss specific gravity, specific gravity formula and its derivation and solved exampl

The specific gravity stands for a dimensionless unit that defines the ratio of density of a substance to the density of water. The density of water is 1000 kg/cubic meters at 4 Celsius. In physics, the weight of the substance differs from its mass. The w
