Poise

P

Definition

The poise is a unit of dynamic viscosity in the CGS system, named after Jean Léonard Marie Poiseuille. It represents the viscosity of a fluid in which a force of one dyne per square centimeter produces a velocity gradient of one centimeter per second per centimeter.

History/Origin

Named after Jean Léonard Marie Poiseuille, a French physicist who studied fluid flow. The poise was the standard unit of dynamic viscosity in the CGS system and is still widely used in many industries.

Current Use

Extensively used in the petroleum industry, chemical engineering, and food processing for measuring the viscosity of oils, polymers, and other fluids. It is often more convenient than the pascal second for practical applications.

Pound-force Second per Square Foot

lbf·s/ft²

Definition

The pound-force second per square foot is an imperial unit of dynamic viscosity, representing the resistance of a fluid to flow when a force of one pound-force per square foot is applied.

History/Origin

This unit originates from the imperial system of measurements, where force is measured in pounds-force and area in square feet. It was commonly used in engineering applications in the United States and other countries using imperial units.

Current Use

Still used in some engineering contexts, particularly in the United States and other countries that use imperial units. It provides a practical measure for engineers working with force-based calculations in imperial units.
