상대 점도와 절대 점도는 유체의 점도를 설명하는 두 가지 개념입니다., 그리고 그들 사이에는 약간의 차이점이 있습니다.

상대점도:

Relative viscosity refers to the viscosity of a fluid at a certain temperature compared to some reference fluid, 일반적으로 용매. It is determined by measuring the flow properties of the fluid with respect to the reference fluid. Relative viscosity is a dimensionless value that indicates the degree to which the viscosity of the fluid increases with respect to the reference fluid. Relative viscosity can be calculated by measuring the movement time or flow velocity of the fluid.

상대점도는 절대점도와 다릅니다.

절대점도:

절대점도란 유체의 실제점도를 말합니다., 동적 점도 또는 동적 점도라고도 함. 부피를 측정하여 결정됩니다. (유량) through which the fluid passes per unit time per unit area. 절대점도는 단위를 갖는 물리량이다., 일반적으로 PASCAL 초에 사용됩니다. (우선권) or millipa ·s (mPa·s).

The absolute viscosity is an intrinsic property of fluid and can be directly used in the calculation and analysis of fluid mechanics. The relative viscosity is the relative value of the reference fluid, which is often used for the measurement of liquid mixtures and the comparison of liquid properties.

North-south tides remind you that the relationship between relative and absolute viscosity can be expressed by a constant, called the constant of proportionality or the conversion factor of relative viscosity to absolute viscosity. 이 변환 계수는 사용된 기준 유체 및 온도 조건에 따라 달라집니다.. To summarize, the relative viscosity is the fluid viscosity comparison value with respect to the reference fluid, while the absolute viscosity is the actual viscous physical quantity of the fluid.
