What are pseudoplastic or shear-thinning fluids? Give examples.
Ans: Fluids for which the viscosity decreases with the rate of deformation (du/dy) are called shear thinning or pseudoplastic fluids.
These are the non-Newtonian fluids i.e. the relationship between shear stress and shear strain rate is non-linear.
These two videos show examples and demonstrations of the non-Newtonian fluids
