Pseudoplastic fluids, also known as shear-thinning fluids, are materials that become less viscous when subjected to stress or shear forces. This means that as they are stirred or mixed, they flow more easily. Common examples include ketchup, paint, and blood, which all exhibit this behavior under different conditions. The unique properties of pseudoplastic fluids make them useful in various applications. For instance, in the food industry, their ability to flow easily when shaken or squeezed allows for better dispensing. In manufacturing, these fluids can be easier to pump and apply, improving efficiency in processes like 3D printing and coating.
