Oxygen - Dynamic and Kinematic Viscosity vs. Temperature and Pressure

Sponsored Links

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

For further definitions, go to Absolute (dynamic) and kinematic viscosity . Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent.

Tabulated values and viscosity units conversion are given below the figures.

Online Oxygen Viscosity Calculator

The calculator below can be used to estimate oxygen dynamic or kinematic viscosity at given temperatures and atmospheric pressure.
The output dynamic viscosity is given as Pa*s, N*s/m2, cP, mPa*s, lbf *s/ft2and lbm /(ft*h),
while the kinematic viscosity is given as cSt, m2/s, and ft2/s
