Fluid Friction Definition, Types, and Factors Affecting

WebFluid friction is the resistance to an object's motion through a liquid or gas. When the motion is occurring in a liquid, it is referred to as viscous resistance. As an example, when an object falls through water, its speed reduces due to fluid friction acting on it. When we add lubricant between two surfaces, fluid friction acts between them.
