👉 A partially fluid, also known as pseudoplastic or shear-thinning fluid, is a material whose viscosity decreases under shear stress. This means that when force is applied to the fluid, such as stirring or pumping, its resistance to flow diminishes. Examples include ketchup, paint, and blood. Under normal conditions, these materials behave more like a solid or a viscous liquid but exhibit fluid-like behavior when subjected to mechanical stress. This property is useful in various applications, from industrial processes to biomedical engineering, where controlled flow characteristics are essential.
