WebThe negative sign indicates that the stress in the fluid opposes the velocity. ... is strictly assigned to mass. To convert a kinematic viscosity to an equivalent absolute viscosity, one must know the liquid’s density at the stated temperature. The old scientific unit, the Stokes, equal to 1 cm 2 /s, is closely related to the poise. WebThe kinematic viscosity v (ny) is the dynamic viscosity divided by density ρ ( rho) when both parameters of the material are taken at the same temperature and pressure. ν = η ρ [ m2 …

WebZero shear viscosity is the viscosity of a material when it is effectively at rest. Despite the misnomer, zero shear viscosity describes a plateau value which you can sometimes see when you use a high-powered rheometer to measure viscosity under extremely low shear conditions. Here are a couple of typical examples and emulsions we measured with ... WebThe poise (symbol P; / p ɔɪ z, p w ɑː z /) is the unit of dynamic viscosity (absolute viscosity) in the centimetre–gram–second system of units (CGS).
