Non-Newtonian fluid

A non-Newtonian fluid has properties that are dissimilar from those of Newtonian fluids. Most usually, the viscosity of non-Newtonian fluids are in need of shear rate. In this fluids, a constant coefficient of viscosity cannot be defined. Various salt solutions as well as melted polymers are non-Newtonian fluids substances such as ketchup, toothpaste, blood, and shampoo are frequently found substances.
