what is the difference between specific gravity and density
of a substance?
Answer Posted / rajesh
Specific gravity is the Ratio of Density of a liquid
(Kg/cubic metr) to the density of Standard liquid (water -
1000 kg/cubic metr)
Density of liquid is defined as Mass per Unit volume
(Kg/cubic metr)
We take Standard liquid as WATER ( Hydraulics), and
Standard Gas as Air (Thermodynamics), as Gas or Liquid both
are Fluids.
Reason for taking std reference as Water or Air --
Water is Universal Solvent,chemically inactive,freely
available etc.
Air posseses all thermodynamic properties, also does not
affect chemically to components,freely available etc.
