Description

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).

Centipoise (cP): A Practical Unit for Viscosity Measurement

The Centipoise (cP) is a subunit of the Poise, widely used to express dynamic viscosity in practical applications. One centipoise equals one-hundredth of a Poise or 0.001 Pascal seconds (Pa·s).

This unit is particularly useful because the viscosity of water at 20°C is approximately 1 cP, providing a convenient reference point. Industries such as food processing, cosmetics, and pharmaceuticals frequently use the centipoise to measure and control the viscosity of products, ensuring consistency and quality.

Employing the centipoise allows for precise and accessible viscosity measurements, facilitating better control over product formulation and processing conditions.
