FAQ

What is Chapman–Rubesin factor?
The Chapman–Rubesin factor formula is defined as the ratio of product of density and viscosity to product of static density and viscosity and is represented as C=(ρ*ν)/(ρe*μe) or Chapman–Rubesin factor=(Density*Kinematic viscosity )/(Static density*static viscosity). The density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object. , The kinematic viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid, Static density, is the density of the fluid when its not moving, or the density of fluid if we are moving relative to the fluid and static viscosity, is the viscosity of continuous flow, viscosity measures the ratio of the viscous force to the inertial force on the fluid.
