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...
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. ...
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) ...
