WebApr 5, 2024 · The unit of measure for the dynamic viscosity is denoted as Centipoise (cP). Measuring Kinematic Viscosity There are few methods to find the kinematic viscosity of a fluid. The most common method to measure the kinetic viscosity is by determining the time it takes a fluid to flow through a capillary tube. The poise is the unit of dynamic viscosity (absolute viscosity) in the centimetre–gram–second system of units (CGS). It is named after Jean Léonard Marie Poiseuille (see Hagen–Poiseuille equation). The centipoise (1 cP = 0.01 P) is more commonly used than the poise itself. Dynamic viscosity has dimensions of , that is, . The analogous unit in the International System of Units is the pascal-second (Pa⋅s):

Webviscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow. Molasses, for example, has a greater viscosity than water. WebPerson as author : Pontier, L.
