DYNAMIC VISCOSITY Meaning and
Definition
-
Dynamic viscosity refers to a fundamental property of fluids that determines their resistance to flow or deformation under the influence of an applied force or shear stress. It is a measure of a fluid's internal friction or resistance to relative motion between its adjacent layers. In simpler terms, dynamic viscosity describes how "thick" or "sticky" a fluid is, determining how easily it flows.
The dynamic viscosity of a fluid is commonly represented by the symbol μ (mu) and is measured in units of Pascal-seconds (Pa·s), which are equivalent to N·s/m². It can also be expressed in other units such as poise (P) or centipoise (cP), where 1 Pa·s equals 10 P or 1000 cP.
Fluids with higher dynamic viscosities exhibit greater resistance to flow and tend to move more slowly under the same applied force or shear stress. For example, honey has a higher dynamic viscosity than water, thus flows more slowly. On the other hand, fluids with lower dynamic viscosities, such as water, flow more easily.
Dynamic viscosity depends on various factors, including temperature, pressure, and the molecular structure of the fluid. The temperature dependence of dynamic viscosity is particularly important, as most fluids become less viscous as temperature increases. This property is often used in industrial processes, such as lubrication systems, where controlling the dynamic viscosity of a fluid is crucial for optimal machine performance and efficiency.

Etymology of DYNAMIC VISCOSITY
The word "dynamic viscosity" derives from various roots.
"Dynamic" comes from the Greek word "dynamis", meaning power or force. This term was adapted into the English language in the early 19th century to refer to actual or active power.
"Viscosity" originates from the Latin word "viscum", which refers to the sticky substance produced by mistletoe berries. In the early 20th century, this term was adopted in English to represent the measure of a fluid's resistance to flow or its thickness.
Combining these roots, "dynamic viscosity" refers to the measure of a fluid's internal resistance to flow or shear when an external force, like pressure or gravity, acts upon it.
