Specific gravity constant value
WebFeb 2, 2024 · The specific gravity of mercury is 13.574 (using water as a reference). To calculate the specific gravity of mercury, you need to follow a couple of steps: Take a volume of mercury, say V = 10 mL. Measure the mass of the volume: m = 135.34 g. Measure the density of mercury: ρ = m [g]/V [cm³] = 135.34 g/ 10 cm³ = 13.534 g/cm³. WebSpecific 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 …

WebCI is defined in terms of Mean Average Boiling Point (Tb) and specific gravity (SG) at 60°F as shown in Equation 10: C I = 87, 552 T b + 473.7 S G − 456.8. According to this CI scale, … WebSep 2, 2024 · ρ = m/V where ρ is the density m is the mass V is the volume What Is Specific Gravity? Specific gravity is a measure of density relative to the density of a reference substance. The reference material could be anything, but the most common reference is pure water. If a material has a specific gravity less than 1, it will float on water.
WebThe specific weight, also known as the unit weight, is the weight per unit volume of a material.. A commonly used value is the specific weight of water on Earth at 4 °C (39 °F), which is 9.807 kilonewtons per cubic metre or 62.43 pounds-force per cubic foot.. Often a source of confusion is that the terms specific gravity, and less often specific weight, are … WebA commonly used value is the specific weight of water on Earth at 4 °C (39 °F), which is 9.807 kilonewtons per cubic metre or 62.43 pounds-force per cubic foot.
