There are four main ones
Thixotropic
Viscosity decreases with stress over time. E.g. Some honey (keep stirring and solid honey becomes liquid)
Rheopectic
Viscosity increases with stress over time. E.g. Cream (the longer you whip it the thicker it gets)
Shear thinning
Viscosity decreases with increased stress. E.g. Ketchup (you have to shake the bottle to get it out)
Dilatant or shear thickening
Viscosity increases with increased stress. E.g. Oobleck (cornstarch and water, looks like a liquid but hit it and it is a solid)
YES, Glycerin is Newtonian fluid.
Glycerin is considered a Newtonian fluid because its viscosity remains constant regardless of shear rate or stress applied. This means that its viscosity does not change with the speed or force applied to it.
Most polymers are non-Newtonian fluids, meaning that their viscosity changes under different shear conditions. However, some polymers can exhibit Newtonian behavior under certain conditions.
yes. example of paraffin flows with increase in stress and flow curve passes through the origin, fitting in the definition of Newtonian 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.
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.
Yes. In the limit where the velocity difference between two observers gets ever closer to zero, the equations of spacial relativity reduce to the Newtonian equations. Indeed, if this were not true, then special relativity would be *wrong*. Similarly, general relativity gives the same answers as Newtonian gravity for the cases in which Newtonian gravity applies.
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 and their flow behavior changes with the applied force or stress.
Yes, newtonian fluid.
No, gum is not a non newtonian
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 physics and relativity differ in their treatment of motion and gravity. Newtonian physics describes motion and gravity based on absolute space and time, while relativity considers them as relative and interconnected. Additionally, relativity accounts for the effects of high speeds and strong gravitational fields, which are not addressed in Newtonian physics.
Benzene is considered a Newtonian fluid. This means that its viscosity remains constant regardless of the shear rate or stress applied to it.
YES, Glycerin is Newtonian fluid.
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.
Yes, quicksand is a non-Newtonian fluid.
