Apparent viscosity is a measure of a fluid's resistance to flow, particularly when the fluid does not behave as a Newtonian fluid. In Newtonian fluids, the viscosity is constant and independent of the applied shear rate. However, many real-world fluids, such as slurries, polymer solutions, and certain emulsions, exhibit non-Newtonian behavior, meaning their viscosity can change with the rate of shear or stress applied.
