Īir dynamic and kinematic viscosity at atmospheric pressure and varying temperature: See also other properties of Air at varying temperature and pressure: Density and specific weight at varying temperature, Density at varying pressure, Diffusion Coefficients for Gases in Air, Prandtl Number, Specific heat at varying temperature and Specific heat at varying pressure, Thermal Conductivity, Thermal Diffusivity, Properties at gas-liquid equilibrium conditions and Air thermophysical properties at standard conditions and Composition and molecular weight ,Īs well as dynamic and kinematic viscosity of ammonia, benzene, butane, carbon dioxide, ethane, ethanol, ethylene, methane, methanol, nitrogen, oxygen, propane and water. While the kinematic viscosity is given as cSt, m 2 /s, and ft 2 /s The output dynamic viscosity is given as Pa*s, N*s/m 2, cP, mPa*s, lb f *s/ft 2 and lb m /(ft*h), The calculator below can be used to calculate air dynamic or kinematic viscosity at given temperatures and atmospheric pressure. Tabulated values and viscosity units conversion are given below the figures. Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent. įor further definitions, go to Absolute (dynamic) and kinematic viscosity.

The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.
