Poise [P]

Poise, symbolized as P, is the standard unit of dynamic viscosity in the centimeter-gram-second (CGS) system. It quantifies a fluid’s resistance to flow under an applied force, specifically describing how much force per unit area is needed to move one layer of fluid relative to another. One poise equals one dyne-second per square centimeter, and it represents a moderate level of viscosity. For comparison, water at room temperature has a viscosity of approximately 0.01 poise, while thicker liquids like honey or glycerin have much higher poise values. Dynamic viscosity is essential in fields like fluid mechanics, chemical engineering, and geophysics, where understanding how fluids flow under different conditions is crucial. Poise is widely used in laboratory measurements and theoretical calculations to predict flow behavior, turbulence, and energy dissipation. It helps engineers design pipelines, lubrication systems, and industrial processes involving liquids. While the SI unit of viscosity is the pascal-second (Pa·s), poise remains relevant in many practical applications and scientific studies due to its historical usage and simplicity in the CGS framework. Understanding poise allows researchers to compare different fluids’ flow characteristics and anticipate how substances will behave under stress or shear.

Gram per Centimeter per Second [g/(cm·s)]

Gram per centimeter per second, symbolized as g/(cm·s), is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system. Dynamic viscosity measures a fluid’s internal resistance to flow when a force is applied. In this unit, it represents the force, in grams, required to move a layer of fluid one centimeter thick over an area of one square centimeter at a velocity of one centimeter per second. High values of g/(cm·s) indicate thicker, more viscous fluids, like honey or heavy oils, while lower values correspond to thinner fluids, such as water or light oils. This unit is commonly used in laboratory measurements, fluid mechanics studies, and chemical engineering processes, particularly when precise small-scale viscosity measurements are needed. Although the SI unit of dynamic viscosity is the Pascal-second (Pa·s), g/(cm·s) remains relevant in CGS-based calculations and historical data. Understanding viscosity in g/(cm·s) helps scientists and engineers design equipment, predict fluid behavior, and ensure efficient operation in pipelines, lubricants, and industrial fluid systems.
