specific gravity .比重、密度 density密度
It is the relative proportion of the Density of the sample to the Density of the reference. Calculation To calculate the Density of any material weight and volume of the substance must be known. To calculate the specific gravity, the Density of the sample material is divided by the Density ...

The specific gravity of wood is its single most important physical property. Most mechanical and physical properties of wood are closely correlated to specific gravity and density. The physicomechanical properties of wood are mainly determined by three characteristics: (i) the porosity or proportion ...

Specific Gravity and Density. The density of spa-water at constant pressure depends both on the salinity and on the temperature. Ry a constant temperature it depends solely on the total salinity, as the latter always shows the same relative composition. Thence wholly equivalent expressions of the...

An introduction to density, specific weight and specific gravity. Density is defined as mass per unit volume . Mass is a property and the SI unit for density is [kg/m3]. Density can be expressed as ρ = m / V = 1 / ν (1) where ρ = density [kg/m3], [slugs/ft3] m = ...
is more or less dense than another. However, because the density of pure water is so close to 1 (0.9976 grams per cubic centimeter), specific gravity and density are nearly the same value so long as the density is given in g/cc. Density is very slightly less than specific gravity....
Density is the mass per unit volume of a material. Specific gravity is a measure of the ratio of mass of a given volume of material at 23°C to the same volume of deionized water. Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and...
