What is meant by the term high and low viscosity?
Viscosity is the measure of resistance of a fluid to flow. A fluid that is highly viscous has a high resistance (like having more friction) and flows slower than a low-viscosity fluid. To think of viscosity in everyday terms, the easier a fluid moves, the lower the viscosity.
What is something with low viscosity?
Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 1, have higher viscosities.
What do you mean by term viscosity?
viscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow.
What happens if viscosity is too low?
Too low viscosity can also lead to excessive volatilization and oil consumption in engines, both of which have a negative environmental impact. Low viscosity equates to small molecules that are more prone to vaporization at high temperatures along the piston ring belt, cylinder wall and exhaust valves.
What is the lowest viscosity liquid?
The least viscous at any temperature must be superfluid liquid helium.
Is water low viscosity?
Viscosity is defined as the resistance to flow! Viscosity is often referred to as the thickness of a fluid. You can think of water (low viscosity) and honey (high viscosity).
Is low viscosity thick or thin?
Viscosity describes a fluid’s internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is “thin”, having a low viscosity, while vegetable oil is “thick” having a high viscosity.
Why is the viscosity of water low?
To sum up: Water has a narrow viscosity spectrum (as a function of temperature) because it has a narrow stress relaxation time spectrum. It has a narrow stress relaxation time spectrum because it is a relatively simple, small molecule.
What is the abbreviation of viscosity?

Does water have low viscosity?
What causes low viscosity?
A decrease in viscosity may also occur when non-lubricants like solvents and diesel fuel accidently get into the lubricant. The high temperatures can sheer/crack the oil molecules into smaller molecules, which causes a decrease in viscosity.
Which of the following fluids is least viscous?
Ethyl alcohol is the least viscous fluid that you could (A) acquire a large enough quantity to swim in, and (B) not die from dipping your body into it.
