Relative Densitydensity

Relative density is the density or ratio of any substance to another substance.  It sometimes may be called just gravity or specific gravity

Relative Density FORMULA

\(\large{ RD = \frac{\rho_s}{\rho_r} }\)         

Where:

\(\large{ RD }\) = relative density

\(\large{ \rho_r }\)   (Greek symbol rho) = reference density

\(\large{ \rho_s }\)   (Greek symbol rho) = substance density
