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)

At what concentration glycerol is Newtonian?
YES, Glycerin is Newtonian fluid.
What do you know about an object if it changes position relative to a reference point?
your question is a but vague. the answer refers to the Newtonian aspect of it: if you have a reference point, then you can measure the difference between the two places of that object. taking time into account, you can derive its velocity and acceleration rate. matar
Are polymer Newtonian fluid?
yes
What is a sentence for non-newtonian fluids?
A non-Newtonian fluid is a fluid whose flow properties are not described by a single constant value of viscosity. Many polymer solutions and molten polymers are non-Newtonian fluids, as are many commonly found substances such as ketchup, starch suspensions, paint, blood and shampoo. 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 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. A ratio between shear stress and rate of strain (or shear-dependent viscosity) can be defined, this concept being more useful for fluids without time-dependent behavior.
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 difference between effective viscosity and apparent viscosity for Non newtonian fluid?
both are same thingwhere, η - Apparent Viscosity
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.
Do relativity equations hold true for normal conditions?
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.
Is benzene a newtonian fluid or non-Newtonian fluid?
Newtonian
Is glycerol a newtonian or non newtonian fluid?
Yes, newtonian fluid.
Is guar gum a newtonian or non newtonian fluids?
No, gum is not a non newtonian
What is the relationship between shear stress and velocity gradient in a Newtonian fluid?
linear
At what concentration glycerol is Newtonian?
YES, Glycerin is Newtonian fluid.
What was the Newtonian achievement?
The Newtonian achievement is the Newtonian telescope. It is a kind of reflecting telescope that was created during the seventeenth century by Isaac Newton
Is Asphalt a Newtonian fluid?
At high temperatures such as 275F (135C), asphalt is a Newtonian fluid. At low temperature, asphalt is a non-Newtonian fluid.
Is ketchup a non-Newtonian fluid?
Some ketchups are newtonian, others are not. The popular brand "Heinz" advertises what would be non-newtonian characteristics.
What are the limitations on Newtonian Mechanics?
The main limitation on Newtonian Mechanics is the size of the objects. As the object gets smaller, it becomes harder for Newtonian Mechanics to apply its laws.
