Notes

The atmospheric boiling point of methanol is 64.15 °C (147.47 °F). Methanol must be pressurized to be present as liquid above that temperature.

Viscosity - Definition

Viscosity is a measure of a fluid's resistance to gradual deformation by shear stress or tensile stress.

Dynamic (Absolute) Viscosity is used to calculate Reynolds Number to determine if fluid flow is laminar, transient, or turbulent.

Kinematic Viscosity is the ratio of dynamic viscosity to fluid density.

Unit Conversions

Dynamic Viscosity

1 cP = 0.001 Pa·s = 2.4191 lb/(ft·h)
1 Pa·s = 1000 cP = 2419.08 lb/(ft·h)
1 lb/(ft·s) = 1488.16 cP

Kinematic Viscosity

1 cSt = 1×10⁻⁶ m²/s = 1.07639×10⁻⁵ ft²/s
1 m²/s = 1×10⁶ cSt = 10.7639 ft²/s
1 ft²/s = 92903.04 cSt
