Viscosity
Viscosity is a measure of a fluid's resistance to deformation or flow. It is a crucial property in fluid dynamics and plays a significant role in various engineering applications.

Poise
Poise is the unit of viscosity in the centimeter-gram-second (CGS) system. It is named after Jean Louis Marie Poiseuille, a French physician who made significant contributions to the field of fluid dynamics.

Relation to Kinematic Viscosity
While poise is the unit of dynamic viscosity, which is the measure of a fluid's internal resistance to flow, kinematic viscosity is the ratio of dynamic viscosity to the fluid's density. Therefore, poise is not directly related to kinematic viscosity.

Importance in Fluid Dynamics
Understanding viscosity, measured in poise, is crucial in various industries such as petroleum, food processing, and pharmaceuticals. It affects the flow behavior of fluids in pipelines, pumps, and other systems.

Conversion to SI Units
In the International System of Units (SI), the unit of viscosity is the Pascal-second (Pa.s). To convert poise to SI units, you can use the conversion factor 1 poise = 0.1 Pa.s.
In summary, poise is the unit of dynamic viscosity in the CGS system, and it plays a vital role in understanding fluid behavior and flow dynamics in various engineering applications.
