How do you calculate reynolds number

WebThe Reynold's Number is a unitless, dimensionless quantity. Knowing the Reynold's Number gives you a way to predict what's the first speed where you might expect turbulence, and therefore the first speed where you might expect Poiseuille's Law to not give you an accurate description of the flow of the fluid. Up next: video. WebFor present purposes, the Reynolds number R is defined as R=LU/ν, where L and U are characteristic length and velocity scales for a flow, and ν is the kinematic viscosity of the fluid. It will be recalled that the non dimensional Reynolds number is a measure of the importance of inertia to viscosity effects.
