ABSOLUTE VISCOSITY Meaning and
Definition
-
Absolute viscosity, also known as dynamic viscosity, refers to the measure of a fluid's resistance to flow under an applied force. It is defined as the ratio of shear stress to shear rate within the fluid. In simpler terms, it quantifies the internal friction between adjacent layers of a liquid or gas when it flows.
The term "absolute" is used to distinguish this viscosity from other types of viscosities, such as kinematic viscosity, which considers the fluid's resistance to flow in relation to its density. Absolute viscosity, however, measures the internal resistance alone and does not depend on any other physical properties of the fluid.
Absolute viscosity is typically measured in units of Pascal-seconds (Pa·s) or poise (P), with 1 Pa·s equivalent to 10 P. It varies with temperature, often decreasing as temperature rises due to increased molecular mobility.
This property plays a crucial role in various fields, including fluid dynamics, automotive engineering, and industrial processing. It affects the efficiency of lubrication, the flow characteristics of fluids within pipes or conduits, and the performance of hydraulic systems. Knowledge of absolute viscosity is therefore essential for designing systems that involve flowing liquids or gases and predicting their behavior under different conditions.
Overall, absolute viscosity provides a fundamental measure of a fluid's ability to flow, allowing engineers, scientists, and researchers to understand and control the behavior of fluids in a wide range of practical applications.

Etymology of ABSOLUTE VISCOSITY
The word "viscosity" comes from the Latin term "viscosus", which means sticky or adhesive. "Viscosus" itself is derived from the Latin verb "viscō", meaning to stick or adhere. The term "absolute" in "absolute viscosity" refers to the intrinsic, independent nature of viscosity, as it does not rely on external factors such as pressure or temperature. The word "absolute" originates from the Latin term "absolutus", meaning free or complete. Therefore, "absolute viscosity" refers to the inherent stickiness or resistance to flow of a substance, regardless of other conditions.
