How the Absolute Viscosity of Common Gases Table works?




This table presents the absolute viscosity of some common fluids and his evolution against the temperature.


Viscosity is the measure of a fluid's resistance to flow. Dynamic viscosity is a measure of internal resistance.It measures the tangential force per unit area required to move one horizontal plane with respect to an other plane.

Viscosity (mu)

It is commonly expressed, particularly in ASTM standards, as centipoise (cP) since the latter is equal to the SI multiple millipascal seconds (mPa·s).The viscosity of a fluid is highly temperature dependent.
