补充资料:黏度
分子式:
CAS号:

性质:(一)动力黏度(dynamic viscosity)的简称。流体内摩擦的定量量度。当流体以层流形式流动时,流体内不同的薄层以不同的速度移动,从而产生内摩擦。内摩擦力的大小与在垂于流动方向上的速度梯度(即切向速度)成正比。为产生单位速度梯度的流动所必须施加的力f=ηA(dv/dx)。式中,dv/dx为速度梯度;A为流体薄层的接触面积;η为黏度。其法定计量单位为Pa·s或mPa·s。(二)过去常认为其为动力黏度、运动黏度(kinematic viscosity)符号为v,定义为v=η/ρ,其中η为动力黏度,ρ为液体密度。即动力黏度除以其密度。法定计量单位为m2/s,化工中常用mm2/s。相对黏度(relative viscosity)为流体的动力黏度与同温度下水的动力黏度之比。为无量纲量。有时也指高分子溶液的动力黏度与同温度下纯溶剂的动力黏度之比。过去常误称为比黏度,甚至误称为黏度。
