Question

Difference between plastic and pseudoplastic flow

Answer 1

Difference between the plastic and pseudoplastic.The plastic gives velocity decreases as shearing rates increases.The psedoplastic gives velocity decreases with an increase shear thinning.

Answer 2

Answer:

Difference between Pseudplastic and plastic flow…

Explanation:

You need to keep in mind that the difference can be better understood in the terms of Newtonian and non-Newtonian flow in liquids or semi liquids.

If we speak of Pseudoplastic these are ones that are believed to exhibit common behavior of both plastic flow and Newtonian flow. So if any liquid exhibits plastic flow and lacks its yield point then it is believed to exhibit Newtonian flow.

This is because Newtonian flow also means that such flow will follow all Newtons laws of motion.

If any liquid exhibits non-Newtonian flow then it is exhibiting Pseudoplastic flow. This is generally observed in liquids that have a much decreased viscosity under the effect of shear strain. Such liquids when flowing exclude time dependent effects.

So if there is any liquid that exhibits shear stress that is not at all proportional directly to the deformation rate, then these types exhibit non-newtonian flow. These are also types that avoid following Newtons laws. Under such the flow curve of these liquids will be non-linear or in simple terms does pass through the origin point.
