absolute viscosity definition
Noun. 1. absolute viscosity-a measure of the resistance to flow of a fluid under an applied force. coefficient of viscosity, dynamic viscosity. coefficient-a constant number that serves as a measure of some property or characteristic. Absolute viscosity-coefficient of absolute viscosity-is a measure of internal resistance. Dynamic (absolute) viscosity is the tangential force per unit area required to move one horizontal plane with respect to an other plane-at an unit velocity-when maintaining an unit distance apart in the fluid. Kinematic viscosity is the ratio of-absolute (or dynamic) viscosity to density-a quantity in which no force is involved. Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with the fluid mass density. Kinematic Viscosity. Kinematic viscosity is the ratio of-absolute (or dynamic) viscosity to density-a quantity in which no force is involved. Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with the fluid mass density. viscosity n pl, -ties 1 the state or property of being viscous 2 (Physics) a 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. 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.
