Description

The Poise (P): A CGS Unit of Dynamic Viscosity

The Poise (P) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system, named after French physician Jean Léonard Marie Poiseuille. It measures the resistance of a fluid to flow, defined as one dyne-second per square centimeter.

In SI units, 1 Poise equals 0.1 Pascal seconds (Pa·s). While the Poise is less commonly used today, it remains relevant in specific scientific contexts, particularly in rheology and fluid mechanics studies.

Understanding the Poise is essential for professionals dealing with legacy data or working in fields where CGS units are still prevalent, ensuring accurate interpretation and application of viscosity measurements.

The Reyn: A British Unit of Dynamic Viscosity

The Reyn is a British unit of dynamic viscosity, named in honor of Osborne Reynolds, a pioneer in fluid mechanics. It represents the force in pound-force required to move a fluid layer over another with a velocity gradient of one inch per second across a one-inch gap.

While the Reyn is largely obsolete, understanding this unit is important when dealing with historical engineering documents and literature. It provides insight into the evolution of viscosity measurement and the development of fluid dynamics as a discipline.

Converting the Reyn to SI units involves multiplying by approximately 6890, yielding the equivalent value in Pascal seconds (Pa·s).
