Which one of the following is a typical example of non-newtonian fluid...
Explanation:
Non-Newtonian Fluid:
Non-Newtonian fluids are those fluids that do not follow Newton's law of viscosity, which states that the shear stress between adjacent fluid layers is proportional to the velocity gradient in the direction perpendicular to the layers. Non-Newtonian fluids have a more complex behavior, with viscosity depending on factors like shear rate, time, and temperature.
Pseudo plastic Variety:
Pseudo plastic fluids are a type of non-Newtonian fluid whose viscosity decreases as the shear rate increases. This means that as the fluid is sheared, it becomes less viscous and flows more easily.
Typical Example:
One typical example of a Pseudo plastic non-Newtonian fluid is milk. When you stir milk, its viscosity decreases, and it becomes easier to pour. This behavior is characteristic of Pseudo plastic fluids.
Therefore, out of the options provided, milk is the typical example of a Pseudo plastic non-Newtonian fluid. Milk exhibits shear-thinning behavior, where its viscosity decreases with increasing shear rate. This property makes it suitable for certain food processing applications where controlled flow and mixing are important.
