Description

Pound-Force Second per Square Foot (lbf·s/ft²): Imperial Unit of Dynamic Viscosity

The Pound-force second per square foot (lbf·s/ft²) is an imperial unit of dynamic viscosity, expressing the force in pound-force required to move a fluid layer over another with a velocity gradient of one foot per second across a one-foot gap.

This unit is primarily used in the United States and other countries employing the imperial system, particularly in industries like aerospace and mechanical engineering. It facilitates the analysis and design of systems involving fluid flow and lubrication within the imperial measurement framework.

Converting lbf·s/ft² to SI units involves multiplying by approximately 47.8803, yielding the equivalent value in Pascal seconds (Pa·s).

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).
