My boat only holds 12 gallons, so SG is no concern to me. My truck holds 260 gallons so I need to know the weight sometimes. You sound awfully smart. Did you go to college? Yes I went to Screw U. And I came close to flippin a 120 footer because of a SG FU. Joe Scotty "Joe" wrote in message om... "Scott Vernon" wrote in message ... "Joe" wrote in message om...

I'm talking #2, not 6, 8 bunker fuel for ships. Yeah your talking about the weight of the fuel. I was talking about specific gravity as compared to water. Specific Gravity is dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. Specific Gravity can be expressed as: SG = = ρ / ρH2O where SG = specific gravity ρ = density of fluid ρH2O = density of water It is common to use the density of water at 4 oC (39° F) as reference - at this point the density of water is at the highest. Thermal Properties of Water Density, Freezing temperature, Boiling temperature, Latent heat of melting, Latent heat of evaporation, Critical temperature .... . Since Specific Weight is dimensionless it has the same value in the metric SI system as in the imperial english system (BG). At the reference point specific gravity has same numerically value as density. Example - Specific Gravity If the density of iron is 7850 kg/m3, 7.85 grams per cubic millimeter, 7.85 kilograms per liter, or 7.85 metric tons per cubic meter - the specific gravity of iron is: SG = 7850 kg/m3/ 1000 kg/m3 = 7.85 where the density of water is 1000 kg/m3. It is critical to understand the specific gravity of fluids you carry on deck in tanks. If you do not.... and just go by volume guessing weight you can get in mucho trouble in a heart beat. I carried fluids that had as high as a 4.6 SG Joe Scotty |
