Specific gravity is very closely related to Density. And it is also known as relative Density. At the industry level, various techniques, like hydrometer, hydrostatic balance, pycnometer, etc., are used to calculate the Density and specific gravity. In this tutorial, we briefly discuss Density ...

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 = ...
Converting Between Density and Specific Gravity Specific gravity values aren't very useful except for predicting whether or not something will float on water and for comparing whether one material is more or less dense than another. However, because the density of pure water is so close to 1 (...
The physicomechanical properties of wood are mainly determined by three characteristics: (i) the porosity or proportion of void volume; the organization of the cell structure; and the moisture content. Density and specific gravity can be calculated at any moisture content. Density decreases as ...
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...
