What are the differences between Newtonian and non-Newtonian fluids and how do these differences affect their flow behavior?
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 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.
What are some examples of Newtonian fluids and how do they behave under shear stress?
Newtonian fluids are fluids that have a constant viscosity, such as water and most oils. When subjected to shear stress, Newtonian fluids exhibit a linear relationship between the shear rate and shear stress, meaning they flow consistently and predictably.
Why is it called non newtonian fluids?
Non-Newtonian fluids are named after Sir Isaac Newton, who described the behavior of regular fluids (Newtonian fluids) with his laws of motion and viscosity. Non-Newtonian fluids deviate from these laws, displaying unusual behaviors such as changes in viscosity under different conditions.
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.

What are newtanion and non newtanion fluids?
Newtonian fluids have a constant viscosity regardless of the applied shear rate, while non-Newtonian fluids have a variable viscosity that changes with the applied shear rate. Examples of Newtonian fluids include water and most oils, while examples of non-Newtonian fluids include ketchup and toothpaste.

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.
What are some non newtonian fluids?
Some common non-Newtonian fluids include cornstarch mixed with water (called oobleck), ketchup, toothpaste, and whipped cream. These fluids exhibit different viscosities depending on the force applied to them, unlike Newtonian fluids which have a constant viscosity.
Viscosity for non-newtonian fluids?
Effective Viscosity for Non-newtonian fluids is usally defined to calculated for pressure losses. See Bingham or Power law fluids characteristics.
