the extent to which a fluid resists a tendency to flow
b. Also called: absolute viscosity
a measure of this resistance, equal to the tangential stress on a liquid undergoing streamline flow divided by its velocity gradient. It is measured in newton seconds per metre squared
Symbol: η. See also kinematic viscosity, specific viscosity

All related terms of 'viscosities'
viscosity
Viscosity is the quality that some liquids have of being thick and sticky .
absolute viscosity
a full name for viscosity , used to distinguish it from kinematic viscosity and specific viscosity
specific viscosity
a measure of the resistance to flow of a fluid , expressed as the ratio of the absolute viscosity of the fluid to that of a reference fluid (usually water in the case of liquids)
kinematic viscosity
a measure of the resistance to flow of a fluid , equal to its absolute viscosity divided by its density
coefficient of viscosity
the measure of the viscosity of a fluid , equal to the force per unit area required to maintain a difference of velocity of one unit distance per unit time between two parallel planes in the fluid that lie in the direction of flow and are separated by one unit distance: usually expressed in poise or centipoise
