aa rela-tive density for the soil is estimated of the order of 45% to 50% in the more surface level, between 10 and 15 m from g.l., 正在翻译,请等待... [translate]
Define key words such as matter, mass, volume, density, and buoyancy. Use the density formula to solve density example problems for density,...
Example 2: A large sample of soil with a volume of 2.0m3 has been collected and taken to the laboratory, where the dry soil mass was found to be 3.0∗103kg. What is the bulk density of this soil sample? Solution: Apply the bulk density formula: γ=mdvt substitute to find: γ=3.0...
The calculation of soil density is performed according to the formula , where Md is the weight of absolutely dry soil in the volume of the drill cylinder (kg); Vs is the volume of the soil sample (m3). ;EFFECT: increase in the accuracy of determining the density of the soil in the ...

英文: If the salt content is constant, for the same soil, the permeability decreases with increase in dry density in a linear relationship within a certain range of dry density; when the dry density is beyond this range, permeability and the dry density are rel中文: 当干容重在一定的范围内...
By this formula, the packing density of the different size distributions of slag and its water requirements were calculated and found to be the same with the testing results. 用该公式计算上述不同粒径分布的矿粉浆体的堆积密度及需水量,计算结果与试验值基本吻合。

Calculating the Density of a Sphere Once you weigh the sphere in question, you have a value for m. Now all you have to do is calculate its volume (V), which you can do if you measure its diameter, d. The density formula is ρ = m/V,...
