Is wheat flour Newtonian fluid

Answer 1

Wheat flour itself is not a Newtonian fluid; it behaves more like a non-Newtonian fluid, particularly when mixed with water to form dough. In this state, the viscosity of the mixture changes depending on the applied stress or shear rate, which is characteristic of non-Newtonian fluids. When kneaded or mixed, the dough exhibits properties like shear-thinning behavior, where it becomes less viscous under stress. Therefore, while the individual components may have Newtonian properties, the overall behavior of a wheat flour dough is non-Newtonian.
