Specific Gravity of Gas

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Specific gravity of gas, abbreviated as \(SG_g\), a dimensionless number, is the ratio of the density of the gas to the density of air at a standard pressure and temperature.

 

Specific Gravity of Gas formula

\(\large{ SG_g = \frac{\rho_g}{\rho_a}  }\)   

Where:

\(\large{ SG_g }\) = specific gravity of gas (air = 1.0)

\(\large{ \rho_a }\) = density of air

\(\large{ \rho_g }\) = density of gas
