what is the specific gravity?
Answers
Answer:
Equations for Specific Gravity. The specific gravity (SG) is a ratio of the density of the substance of interest (ρ i) to the density of the reference substance (ρ r).
Explanation:
basically it is a ratio of density two substances. where one of the substance is standars such a for solids & liquid its water (whose density is 100 gm/lit) and for gases we use standard as dry air ( whose density is 1.975 gm/lit)
Explanation:
example
if u wnt to find specific gravity of mercury then you have to divide density of mercury to density of water
=13600/1000
= 13.6
so basically to get spcific gravity of whichever substance just divide its density by the density of water ( note this is only for solids & liquids)
for gases like co2 divide its density by dry air
