Figures and tables showing how the properties of water changes along the boiling/condensation curve (vapor pressure, density, viscosity, thermal conductivity, specific heat, Prandtl number, thermal diffusivity, entropy and enthalpy).
The density of water is 1.0 g/mL at room temperature, so the specific gravity is equal to the density of the object expressed without a unit. When substances dissolve in water, the density of the solution is usually different from pure water.
At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml, 1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ft. At 4°C pure water has a specific gravity of 1. ( Some reference the s.g. base temperature as 60F.) Water is essential for life.
Specific gravity (SG), also known as relative density, is a dimensionless quantity that represents the ratio of the density of a substance to the density of a reference substance, typically water for liquids and solids, and air for gases.
Specific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. Physicists use 39.2 F (4 C) as the standard, but engineers ordinarily use 60 F.
Specific Gravity (Relative Density) - SG - is a dimensionless unit defined as the ratio of the density of a substance to the density of water - at a specified temperature and can be expressed as. SG = ρ substance / ρ H2O (2) where SG = Specific Gravity of the substance ρ substance = density of the fluid or substance [kg/m 3]
