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.

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 that changes with the applied stress or shear rate. This results in non-linear flow behavior, unlike the linear flow seen in Newtonian fluids.
Yes, quicksand is a non-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.
Yes, blood is considered a non-Newtonian fluid because its viscosity changes with the rate of flow.
Effective viscosity refers to the equivalent viscosity of a non-Newtonian fluid under specific flow conditions, while apparent viscosity is a term used to describe the measured viscosity of a non-Newtonian fluid, which may vary depending on the test method used. The effective viscosity takes into account the non-linear behavior of the fluid, while the apparent viscosity provides a simplified representation of its flow properties.
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.
