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 specific gravity的区别 答案 首先,weight...
Specific Weight (or force per unit volume) can be expressed as γ = ρ ag(4) where γ = specific weight (N/m3), (lb/ft3) ρ = density (kg/m3), (slugs/ft3) ag=acceleration of gravity(9.807 m/s2, 32.174 ft/s2under normal conditions) ...

specific gravity:比重 例句与用法:1. Granted the weight and the specific gravity of a body, we can calculate its volume.假设已知一个物体的重量和比重，我们就能算出它的体积。英英解释:名词specific gravity:1. the density of a substance relative to the density of water 比重...
Specific Weight Specific weight is a similar sounding word of specific gravity but these are two very different quantities. Weight is defined as the force on a mass due to the gravitational field of another object. Since weight is a force, it’s measured in newton. Specific weight is defined...
Related to specific gravity:Specific weight [grav´ĭ-te] 1.the phenomenon by which two bodies having mass are attracted to each other. 2.the gravitational attraction near a large body having mass, particularly near or on the surface of a planet or star. ...
Granted the weight and thespecific gravityof a body, we can calculate its volume. 假设已知一个物体的重量和比重, 我们就能算出它的体积. 辞典例句 Objective : To study operation, efficacy and safety of Ropivacaine in lightspecific gravityspinal block. ...
Granted the weight and the specific gravity of a body, we can calculate its volume. 假设已知一个物体的重量和比重,我们就能算出它的体积。 Once the desired specific gravity is established, the same strength must be used henceforth. 所需的比重一经确定,以后就必须使用同一浓度的酸。
