Benzene - Dynamic and Kinematic Viscosity vs. Temperature and Pressure

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 Liquid Benzene Viscosity Calculator

The calculator below can be used to estimate liquid benzene dynamic or kinematic viscosity at given temperatures. The calculator gives the viscosity at saturation pressure. For most practicle issues this can be used for liquid benzene at any pressure up to the critical point (289°C, 49 bara or 552°F, 712 psia)
The output dynamic viscosity is given as Pas, Ns/m², cP, mPas, lb_fs/ft² and lb_m/fth, while the kinematic viscosity is given as cSt, m²/s and ft²/s.
