specific weight = weight/volume就是比重,单位是 (N/m^3或者 lb/ft^3)而gravity 指的是地心引力,所以不是用力来算的,而是用密度,所以,specific gravity=density /density of water @4 摄氏度,可翻译为相对密度,,没有单位(无量纲)。 结果一 题目 specific weight与 spec

Example 2: Using Density to Identify a Material An unknown liquid substance has a mass of 18.5 g and occupies a volume of 23.4 ml (milliliter). The density of the substance can be calculated as ρ = ((18.5 g) / (1000 g/kg)) / ((23.4 ml) / ((1000 ml/l) (1000 l/m3))) ...

Multiply the specific weight of the substance by the volume to calculate the weight. In this example, the weight is 8240.4 x 0.0052 = 42.85 newtons. Note that "newton" is a unit of force in physics. References Density, Specific Weight and Specific Gravity ...
Specific weightisthe ratio of the weight to the volumeof a substance: γ = m g / V =ρ g (2) where γ = specific weight, units typically (N/m3) or (lbf/ft3) m = mass, units typically (g) or (lb) g = acceleration due to gravity, units typically (m/s2) and value on Earth...
Once you know the mass, you have to convert to weight only if you're using the imperial measurement system. TL;DR (Too Long; Didn't Read) Specific gravity is the density of a substance divided by the density of water. Once you know density, you know mass per unit volume, and from ...
