WebV is the relative velocity, c is the model chord, ρ is the density of the fluid, and μ is the dynamic viscosity of the fluid. The ratio μ/ρ is called ν, the kinematic viscosity, also depending on the fluid density and temperature. For dry air at standard sea level conditions the value of ν is 14.6 × 10 −6. The higher the Reynolds ... WebThe kinematic viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid, i.e. (7.25) and depends on both air …

WebThe cgs unit of viscosity is poise (P), which has been used in honour of French physiologist Jean Léonard Marie Poiseuille. It is also commonly used as centipoise (cP), particularly in ASTM standards. The cgs unit for kinematic viscosity is stoke (St) and has been named after Irish mathematician and physicist Sir George Gabriel Stokes. WebDynamic viscosity is an empirical function of temperature, and kinematic viscosity is calculated by dividing dynamic viscosity by the density. Thus the standard consists of a … WebQuestion: 3.
