Calculating Effective Specific Gravity for Blended Tank Chemistry: Mixing Rules, ASTM D1298 Hydrometer Verification, and Why the Wrong SG Value Cracks Tanks
Plastic tank specifications carry a single specific gravity rating - 1.0, 1.5, 1.7, 1.9, sometimes 2.0 for specialty service. The SG rating is the design basis for tank wall thickness; the wall must h…
