Methanol Dynamic Kinematic Viscosity Temperature Pressure

Overview

Engineering reference data for Methanol Dynamic Kinematic Viscosity Temperature Pressure in fluid mechanics.

Key Formulas

Reynolds Number

$Re = \frac{\rho v D}{\mu}$

Ratio of inertial to viscous forces — determines flow regime.

Bernoulli's Equation

$P + \frac{1}{2}\rho v^2 + \rho g h = \text{const}$

Conservation of energy for steady, inviscid, incompressible flow.

Continuity Equation

$A_1 v_1 = A_2 v_2$

Conservation of mass for incompressible flow.

Darcy-Weisbach

$\Delta P = f \frac{L}{D} \frac{\rho v^2}{2}$

Pressure drop due to friction in a pipe.

Viscosity Data Table

The following table provides the dynamic and kinematic viscosity of liquid methanol at specified temperatures. Note that the atmospheric boiling point of methanol is 64.15 °C (147.47 °F). Methanol must be pressurized to remain as a liquid above this temperature; values marked with an asterisk (*) correspond to pressurized conditions.
