Kinematic viscosity is a measure of a fluid's resistance to flow under the influence of gravity. It combines the fluid's dynamic viscosity, which indicates how thick or sticky it is, with its density. This property is important in various fields, including engineering and fluid dynamics, as it helps predict how fluids behave in different conditions. Kinematic viscosity is typically expressed in units of square meters per second (m²/s) or centistokes (cSt). It plays a crucial role in applications such as lubrication, hydraulics, and chemical processing, where understanding fluid movement is essential for efficiency and safety.
