METHODS FOR THE DETERMINATION OF SPECIFIC GRAVITY

Specific gravity values are primarily used in the orifice meter flow correction calculations and for custody transfer. The fundamental orifice flow equation is a mass other end. When the buoyant force of the gas sample and air taken on successive tests is equal, the densities are equal. A mercury manometer measures the pressures at which this equality occurs, and the pressure ratio is used in calculating specific gravity. This instrument calculated specific gravity …
