What are the differences between Newtonian and non-Newtonian fluids and how do these differences affect their flow properties?
Newtonian fluids have a constant viscosity regardless of the applied stress, while non-Newtonian fluids have a viscosity that changes with stress. This affects their flow properties as Newtonian fluids flow consistently, following Newton's law of viscosity, while non-Newtonian fluids can exhibit different flow behaviors such as shear-thinning or shear-thickening, depending on the stress applied.

Newtonian fluids have a constant viscosity regardless of the applied stress, while non-Newtonian fluids have a viscosity that changes with the applied stress. This difference affects their flow behavior as Newtonian fluids flow consistently, following Newton's law of viscosity, while non-Newtonian fluids can exhibit complex flow patterns such as shear-thinning or shear-thickening behavior.
What is a non Newton fluid?
A non-Newtonian fluid is a fluid whose viscosity changes under stress or deformation. Unlike Newtonian fluids, such as water or air, non-Newtonian fluids do not follow Newton's law of viscosity. Examples include ketchup, custard, and quicksand.
What are the key differences between Newtonian fluids and non-Newtonian fluids?
Newtonian fluids have a constant viscosity, meaning their flow behavior is consistent regardless of the applied force. Non-Newtonian fluids, on the other hand, have variable viscosity and their flow behavior changes with the applied force or stress.
What is the difference between Newtonian and non-Newtonian fluid?
Water is an example of a Newtonian fluid. Non-Newtonian fluids include catsup, paint, liquid detergent, liquid polymers and a variety of other liquids. In a Newtonian fluid, the relation between the shear stress and the strain rate is linear, the constant of proportionality being the coefficient of viscosity. In simple terms, the size of the drops is directly related to the thickness of the fluid, all else being equal. In a non-Newtonian fluid, the relation between the shear stress and the strain rate is nonlinear, and can even be time-dependent. Therefore a constant coefficient of viscosity can not be defined. Multi-viscosity motor oil, which changes viscosity with temperature, is a common example. Newtonian fluids obey Newton's laws.but non Newtonian fluids does not obey Newton's laws.

Is gasoline newtonian fluid?
yes. example of paraffin flows with increase in stress and flow curve passes through the origin, fitting in the definition of Newtonian fluids.
What is the substance that loses its shape under certain conditions?
A substance that loses its shape under certain conditions is called a non-Newtonian fluid. These fluids can change their viscosity and flow properties when subjected to stress or shear forces, causing them to behave differently from traditional Newtonian fluids like water or oil. Examples of non-Newtonian fluids include cornstarch mixed with water (oobleck) and certain types of paint.

What material is a liquid and solid?
Non-newtonian fluids are liquids that resemble the properties of a solid when put under stress.
What are the benefits of newtonian fluid?
Newtonian fluids have constant viscosity, meaning they exhibit a linear relationship between shear stress and shear rate. This makes them predictable and easy to model in fluid dynamics calculations. Newtonian fluids are commonly found in everyday liquids like water, milk, and gases.
Is glue newtonian or non newtonian?
Glue is typically considered a non-Newtonian fluid because its viscosity can change with the applied force, such as stirring or spreading. The viscosity of non-Newtonian fluids like glue can vary depending on factors like shear rate and stress.
Is Asphalt a Newtonian fluid?
No, asphalt is not a Newtonian fluid. It is a non-Newtonian fluid, meaning its viscosity changes with the rate of shear stress. This is why asphalt can behave differently under various conditions and temperatures.
What is the difference between a newtonian and non-newtonian?
There are four main onesThixotropicViscosity decreases with stress over time. E.g. Some honey (keep stirring and solid honey becomes liquid)RheopecticViscosity increases with stress over time. E.g. Cream (the longer you whip it the thicker it gets)Shear thinningViscosity decreases with increased stress. E.g. Ketchup (you have to shake the bottle to get it out)Dilatant or shear thickeningViscosity increases with increased stress. E.g. Oobleck (cornstarch and water, looks like a liquid but hit it and it is a solid)
