Answer:
= Relative Density) - SG - is a dimensionless unit defined as the ratio of the density of a substance to the density of a reference substance - at a specified temperature and pressure, and can be expressed as
SG = ρsubstance / ρreference (3)
where
SG = Specific Gravity of the substance
ρsubstance = density of the fluid or substance [kg/m3]
ρreference = density of the reference [kg/m3]
