Dynamic viscosity of air at sea level metric
Web7.9.1 Kinematic Viscosity ( ν) The kinematic viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid, i.e. and depends on both air temperature and pressure. For air at sea level pressure and 20 °C, ρ = 1.205 × 10 −3 g cm −3 and ν = 0.15 cm 2 s −1. WebEnter the email address you signed up with and we'll email you a reset link.
