    For pseudoplastic fluids, also known as shear-thinning fluids, the apparent viscosity decreases with an increase in shear rate. This behavior is due to the alignment of the fluid's internal structure (such as polymer chains or suspended particles) in the direction of the flow, which reduces internal resistance and thus the viscosity.
