Viscosity cst unit

Abstract: 本文介绍了粘度的基本概念及其相关单位厘斯(cSt)的定义与换算。厘斯(cSt)是运动粘度的单位,代表1/100的斯托克斯。文中详细阐述了动力粘度、运动粘度和条件粘度的测定方法,以及各类粘度单位的换算关系。此外,文章还介绍了粘度与温度、压力之间的关系,并强调粘度测定在工业生产及各行业中的重要性。最后,文章简要介绍了粘度测定的历史背景和纳维-斯托克斯方程的基础性贡献。

Concept

Centistokes (cst) is the smallest unit of kinematic viscosis. cSt is the abbreviation of Centistokes, which means centistokes, which is one hundredth of 1 stox. 


The unit of kinematic viscosity is Stokes, that is, Stokes, referred to as S. When the dynamic viscosity of the fluid is 1 poise and the density is 1 g/cm3, the kinematic viscosity is 1 Stokes.

Extended reading of viscosity

Common viscosity unit conversion:


1 centipoise (1cP) = 1 mPascal. Second (1mPa.s)


100 centipoise (100cP) = 1 poise (1P)


1000 mPascal. Second (1000mPa.s) = 1 Pascal. Second (1Pa.s)


Conversion of dynamic viscosity and kinematic viscosity:


η = ρ.ρ.


Where η --- Specimen dynamic viscosity (mPa.s)


Viscosity of specimen (mm2/s)


Rp --- the density of the sample at the same temperature as the measured kinematic viscosity (g/cm3)


For liquids, the greater the pressure, the lower the temperature, and the greater the viscosity; the smaller the pressure, the higher the temperature, and the smaller the viscosity.


For gases, pressure has little effect; the higher the temperature, the greater the viscosity, and the lower the temperature, the smaller the viscosity.
