Find the dynamic (absolute) viscosity values for a wide range of liquids in both SI (mPa·s) and US customary (lbf·s/ft²) units.
Table of data giving the viscosity of many common liquid substances used in process industries.
Viscosity is resistance to shear or flow in a fluid - and a measure of the adhesive/cohesive or frictional property. Viscosity arising due to internal molecular friction produces the frictional drag effect. There are two related measures of fluid viscosity - known as dynamic (or absolute) and kinematic viscosity.
Dynamic (Absolute) Viscosity - Converting Chart Convert dynamic viscosity values between units like Poiseuille - Poise - centiPoise and more. Engine & Gear Oil - Recommended Viscosity vs. Outside Temperature
The kinematic viscosity of a liquid can be looked upon as the liquid's resistance to flow under its own gravity head. ν = η/ρ. Units for Kinematic Viscosity: ft 2 / s. mm 2 / s. m 2 / s. The following table defines the average Kinematic Viscosity for selected liquid fluids. The data shown yellow can be changes to recallate the selected variables.
For liquid, the dynamic viscosity is usually in the range of 0.001 to 1 Pascal-second, or 1 to 1000 centiPoise. The density is usually on the order of 1000 kg/m^3, i.e. that of water. Consequently, if a liquid has dynamic viscosity of n centiPoise, and its density is not too different from that of water, then its kinematic viscosity is around n ...
Viscosity of Liquids and Gases. Viscosity has the SI units Pascal seconds (Pa s) which is called the Poiseuille. More commonly used is the dyne sec/cm 2 which is called Poise. One Pa s is 10 Poise. The Poise is used in the table because of its more common usage. Data from Gustafson.
