Is honey shear thinning?

Yes, honey is considered a shear-thinning fluid, meaning it becomes less viscous and flows more easily when subjected to shear stress, such as stirring or pouring.


Various drilling mud have the same apparent viscosity at 1022sec-1 but the effective viscosity at other shear rates may vary widely Explain?

Drilling mud is a nonnewtonian fluid. It's a thixotropic fluid and it's apparent viscosity is a function of shear rate and time so at various shear rate and times you will have various viscosities. The molecular structure of these fluids breaks during tention.For further informations you can refer to rheology or fluid mechanics books.


Can you provide an example of shear thinning in a material?

An example of shear thinning in a material is when ketchup becomes easier to pour as you apply force to it, but thickens back up when the force is removed.


Is shear thinning fluids and the linear viscoelastic fluids are the same?

no


What are some examples of materials that exhibit shear thinning behavior?

Some examples of materials that exhibit shear thinning behavior include ketchup, toothpaste, and certain types of paint. These materials become less viscous and flow more easily when subjected to shear stress, such as when being squeezed or stirred.


What is the relationship between shear stress and shear rate in fluid mechanics?

In fluid mechanics, shear stress is the force per unit area applied parallel to the surface of a fluid, while shear rate is the rate at which adjacent layers of fluid move past each other. The relationship between shear stress and shear rate is described by Newton's law of viscosity, which states that shear stress is directly proportional to shear rate. This means that as the shear rate increases, the shear stress also increases proportionally.


WHAT IS PSEUDO PLASTIC?

Pseudo plasticity discusses to the decrease of viscosity when shear forces are applied. The tougher the shear stress the pseudo plastic material is subjected to, the tougher the shear thinning effect and the tougher the reduction in viscosity.


What is pseudo-plastics?

Pseudo plasticity discusses to the decrease of viscosity when shear forces are applied. The tougher the shear stress the pseudo plastic material is subjected to, the tougher the shear thinning effect and the tougher the reduction in viscosity.


What is the relationship between the shear g and the shear rate?

Viscosity is constant to the flow of the fluid.


What is the formula for calculating wall shear stress in fluid dynamics?

The formula for calculating wall shear stress in fluid dynamics is du/dy, where represents the wall shear stress, is the dynamic viscosity of the fluid, and du/dy is the velocity gradient perpendicular to the wall.


Why shear force is necessary for fluid flow?

Shear force is necessary for fluid flow because it creates a differential in velocity within the fluid, allowing it to move from one point to another. This shear force helps overcome the internal friction in the fluid and facilitates the movement of fluid particles along a surface or past each other. In essence, shear force is responsible for driving the flow of fluids.


What is shear flow?

Shear flow is the flow induced by a force gradient (for a fluid). For solids, it is the gradient of shear stress forces throughout the body.
