![]() ![]() WebThe quantity defined above is sometimes called dynamic viscosity, absolute viscosity, or simple viscosity to distinguish it from the other quantity, but is usually just called viscosity. WebThe kinematic viscosity n (SI units m2/s) is, by definition n ¼ m r The Prandtl number is, by definition, Pr ¼ c Pm k For consistency this may be found by substitution. Viscosity of Air, Dynamic and Kinematic - Engineers Edge The density of the air can be estimated with the Ideal Gas Law ρ = p / (R T) = (1 105 N/m2) / ( (287 J/ (kg K)) ( (273 oC) (33 oC)) ) = … bird house for cardinal Calculate the density of the air from the ideal gas law: ρ = P/ (RT) = 105 Pa/ (287.05 J/kg
