Methanol - Dynamic and Kinematic Viscosity vs. Temperature and Pressure (original) (raw)
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 methanol viscosity and viscosity units conversion are given below the figures.
Online Methanol Viscosity Calculator
The calculator below can be used to estimate dynamic or kinematic viscosity of liquid methanol at given temperatures. The atmospheric boiling point of methanol is 64.15 °C (147.47 °F), and methanol must be pressurized to be present as liquid above that temperature.
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.

Dynamic and kinematic viscosity of liquid methanol at varying temperature:
The atmospheric boiling point of methanol is 64.15 °C (147.47 °F), and methanol must therefore be pressurized to be present as liquid above that temperature.
