The title says it all what are the differences between Pseudo-plastic and Bingham plastic?
A pseudo-plastic fluid is a type of non-Newtonian fluid that exhibits a decrease in viscosity with increasing shear rate. This means that as the fluid is subjected to more force or stress, it flows more easily.
A Bingham plastic fluid is also a type of non-Newtonian fluid, but it exhibits a constant viscosity at low shear rates and then behaves like a Newtonian fluid at higher shear rates. This means that the fluid only starts to flow once a certain amount of force or stress is applied.
The main difference between these two types of fluids is how they respond to shear stress. Pseudo-plastic fluids decrease in viscosity with increasing shear rate, while Bingham plastic fluids have a constant viscosity at low shear rates and then behave like a Newtonian fluid at higher shear rates.
Some common examples of Pseudo-plastic fluids include ketchup, toothpaste, and blood. These fluids exhibit a decrease in viscosity when subjected to shear stress, making them easier to pour, spread, or flow.
Examples of Bingham plastic fluids include mayonnaise, peanut butter, and clay. These fluids have a constant viscosity at low shear rates, but once a certain amount of force is applied, they start to flow like a Newtonian fluid.
