viscosity measurement

Viscosity is a measure of a fluid's resistance to flow. It tells us how "thick" or "sticky" a liquid is—think of honey versus water. To measure viscosity, scientists use devices like viscometers, which determine how easily a fluid flows through a narrow passage or how it pours under specific conditions. Higher viscosity means the fluid flows slowly, while lower viscosity means it flows easily. Understanding viscosity is important in various fields, including engineering, food science, and medicine, as it affects processes such as mixing, pumping, and the behavior of liquids in different environments.
