AF-Reynolds number

By | 9 December, 2018
The Reynolds number is defined as:
Reynolds number
Where:

– ρ is the density of the Air/Fluid (SI units: kg/m3).
– u is the velocity of the Air/Fluid with respect to the object (m/s).
– L is a characteristic linear dimension (m).
– μ is the dynamic viscosity of the Air/Fluid (Pa·s or N·s/m2 or kg/m·s).
– ν is the kinematic viscosity of the Air/Fluid (m2/s).
