METHODS FOR THE DETERMINATION OF SPECIFIC

2015-3-2  Specific Gravity is formally defined as the ratio of gas density to air density when both are at standard conditions of 0 Degree C and 760 mm Hg. Over the years the definition evolved to become the ratio of gas density to air density at the same temperature and pressure, “Relative” to each other. Hence, the term “Relative Density”. This is the most commonly used definition today. The fixed or “Specific”
