What is viscosity?

Explanation:
Viscosity is the resistance of a liquid to flow. It describes how thick or sticky a liquid is and the internal friction that occurs as it moves. High-viscosity liquids, like honey, resist flowing and pour slowly, while low-viscosity liquids, like water, flow readily. This concept matters in pipelines and pumps because viscosity determines how much energy is needed to move the fluid and how it will behave under pressure. It’s different from density, which is about how much mass is in a given volume, not how easily the liquid flows; color is simply an appearance property; temperature can affect viscosity but is not the definition of it.
