kinematic viscosity

Kinematic viscosity measures a fluid's resistance to flow when gravity is the driving force. It describes how easily a fluid moves under its own weight, taking into account both its internal friction (viscosity) and its density. Think of it as how quickly or slowly a drop of fluid will spread or flow through a container or pipe. Higher kinematic viscosity means the fluid flows more slowly, like honey, while lower viscosity means it flows more easily, like water. It’s expressed in units like square meters per second (m²/s).
