Viscosity is a measure of a fluid’s resistance to flow. It is influenced by the internal friction between molecules in the liquid.
High-viscosity fluids resist flow and have a thick consistency, like honey or molasses, while low-viscosity fluids flow more easily and have a thinner consistency, like water.
Viscosity is crucial in various fields, including physics, engineering, and industry, affecting the performance of liquids in processes such as lubrication, transportation, and manufacturing. The unit of measurement for viscosity is typically expressed in terms of poise or pascal-seconds.
