Fluid viscosity can be changed by several methods so the answer is it depends on the application.
For most fluids, viscosity is a function of temperature so increasing temperature can reduce the viscosity.
Fluids can also be diluted with a solvent. Examples would be honey and water or paint and paint thinner.
Fluid viscosity is also a function of the length of the molecules that form your fluid. An example would be long carbon chain molecules that can be chemically broken and therefore shortened thus reducing the viscosity of the fluid.
I'm sure there are other methods but hopefully one of these will be of value.
What else can I help you with?
Derive the relation between relative viscosity and absolute viscosity?
Relative Viscosity often refers to that of a Polymer Solution and is defined as the ratio of the viscosity of the solution to the pure solvent. It is calculated experimentally by measuring the time that it takes for the pure solvent to pass through a certain tube, in certain conditions , and comparing it with the time it takes for the solution to pass through the same tube, in the same condition. The term Apparent Viscosity is used when you calculate the viscosity of a non-Newtonian fluid by applying equations that are derived for the viscosity of a Newtonian fluid. So it is not the actual viscosity. I hope this answers your question.
In the viscosity what did you change to test viscosity?
To test viscosity, I changed the temperature of the fluid, as viscosity is highly temperature-dependent. I also altered the shear rate by modifying the speed of the stirring or flow conditions. Additionally, I used different fluid compositions or additives to examine how these variations affected viscosity measurements. These changes allowed for a comprehensive understanding of how various factors influence a fluid's resistance to flow.
What is relative viscosity?
Relative viscosity is a measure of a fluid's resistance to flow compared to that of a reference fluid, often water. It is calculated by dividing the viscosity of the fluid by the viscosity of the reference fluid. Relative viscosity is commonly used in the study of fluid dynamics and in industries such as oil and gas, chemicals, and food processing.
What is the viscosity definitions?
Viscosity is a fluids resistance to flow. A high viscosity fluid would be thick, a low viscosity fluid would be thin.
How does the viscosity of O obleck change with force?
The viscosity of oobleck, a non-Newtonian fluid, decreases with applied force or shear stress. When a force is applied, the cornstarch particles in the oobleck align and create a more fluid-like behavior, lowering its viscosity.
Is viscosity a chemical or a physical change?
viscosity is a physical characteristic not a physical change. it is the thickness of a substancephysical changes would be if it turned from solid into a liquid.for example a chocolate bar goes through a physical change when it becomes melted chocolate.
A fluid resistance to flow is called?
A fluid's resistance to flow is called its viscosity.
Is glycerin a newtonian or non-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.
What factors determine the viscosity of a fluid if viscosity does not depend on temperature?
The factors that determine the viscosity of a fluid, when viscosity is not affected by temperature, include the size and shape of the molecules in the fluid, the presence of any impurities or additives, and the pressure under which the fluid is being measured.
Do all liquids flow very easily?
Runny depends on the viscosity of a fluid. if the viscosity is high( mayonaise) the fluid will not run as good as a fluid with low viscosity (water, honey)
A fluid resistance to flow?
Viscosity is the fluid property that measures its resistance to flow. It determines how easily a fluid can deform and flow. Fluids with high viscosity, like honey, flow more slowly than fluids with low viscosity, like water.
Define inviscid fluid?
a fluid which has no viscosity
