Ethanol - 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 of ethanol viscosity and viscosity units conversion are given below the figures.
Online Ethanol Viscosity Calculator
The calculator below can be used to calculate ethanol dynamic or kinematic viscosity at given temperatures and atmospheric pressure.
The output dynamic viscosity is given as Pas, Ns/m2, cP, mPas, lbfs/ft2 and lbm/fth, while the kinematic viscosity is given as cSt, m2/s and ft2/s.
