Viscosity - Wikipedia
In fluid dynamics, it is sometimes more appropriate to work in terms of kinematic viscosity (sometimes also called the momentum diffusivity), defined as the ratio of the dynamic viscosity (μ) over the density of the fluid (ρ).
Viscosity - Absolute (Dynamic) vs. Kinematic
Kinematic Viscosity. Kinematic viscosity is the ratio of - absolute (or dynamic) viscosity to density - a quantity in which no force is involved. Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with the fluid mass density like. ν = μ / ρ (2) where

2021年5月7日 · The dynamic viscosity coefficient divided by the density is called the kinematic viscosity and given the Greek symbol nu. nu = mu / r Re = V * L / nu The units of nu are length^2/sec. Here's a Java program to calculate the coefficient of viscosity and the Reynolds number for different altitude, length, and speed.
Definition:Kinematic Viscosity - ProofWiki
The usual symbol used to denote the kinematic viscosity of a fluid is ν ν . Its LATEX L A T E X code is \nu . The dimension of measurement of kinematic viscosity is L2T−1 L 2 T − 1 . The SI unit of measurement of kinematic viscosity is the square metre per second .
Kinematic Viscosity Formula, Overview, Definition
2023年10月3日 · Kinematic viscosity, denoted by the symbol ν (nu), is a derived parameter that relates dynamic viscosity to density. It quantifies how fast a fluid can flow under the influence of gravity and is particularly useful for comparing the flow properties of fluids with different densities.
Viscosity and Shear - What are they? - Michael Smith Engineers
Kinematic viscosity is the ratio of absolute (dynamic) viscosity (μ) – see the previous sections - to density (ρ) and is a measure of a fluid’s inherent resistance to flow when no external force, except gravity, is acting on it. The symbol for kinematic viscosity is nu: ν and its SI units are m/s 2.
