Gas Density (ρg)
Gas density is defined as the mass of the gas occupying a certain volume at specified pressure and temperature.
Gas density is a function of the pressure and temperature conditions for the gas. Due to its high compressibility, gas can change its volume significantly with change in pressure. Therefore, density changes (at low pressure) can be significant.
