A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.
What does viscosity mean kid definition?
Viscosity is the property of
a liquid that describes how fast or slowly it will flow
. … A liquid with high viscosity – that is thick, like peanut butter – will flow slowly. A liquid with low viscosity, or that’s thin, like water, will flow quickly (in other words, it will flow freely).
What is viscosity and example?
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. … Molasses, for example, has a greater viscosity than water.
What is the meaning of word viscosity?
1 : the quality or state of being viscous :
a sticky or glutinous consistency
. 2a technical : the property of resistance to flow in any material with fluid properties … water has a small but measurable viscosity, or “stickiness,” which results from the weak mutual attraction of water molecules.—
What is viscosity of a liquid?
The viscosity of a fluid is
a measure of its resistance to deformation at a given rate
. For liquids, it corresponds to the informal concept of “thickness”: for example, syrup has a higher viscosity than water. … A fluid that has no resistance to shear stress is known as an ideal or inviscid fluid.
What is viscosity volcano?
The most important factor in determining the shape or type of volcano is the
viscosity of the magma that builds the volcano
. Viscosity is a measure of a fluid material’s resistance to flow and results from the internal forces and friction between the material’s molecules.
What are some real life examples of viscosity?
- Honey.
- Engine Oil.
- Brake Oil.
- Lubricant.
- Cooking Oil.
- Liquid Soap.
- Printing Ink.
- Super Glue.
What is the another name of viscosity?

How is viscosity calculated?
There are several formulas and equations to calculate viscosity, the most common of which is
Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v)
, where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid.
What causes viscosity?
Viscosity is a measure of the resistance of a fluid towards being deformed when under shear stress. Hence, it is also known as shear viscosity. It is caused by
the attractive forces between molecules in close contact, and the friction between molecular chains
.
What are the types of viscosity?
- Dynamic Viscosity. Dynamic viscosity measures the ratio of the shear stress to the shear rate for a fluid.
- Kinematic Viscosity. Kinematic viscosity measures the ratio of the viscous force to the inertial force on the fluid. …
- Common Units. …
- Newtonian Fluids. …
- Non-Newtonian Fluids.
What is the root word of viscosity?
viscous (adj.)
late 14c., from Anglo-French viscous and directly from
Late Latin viscosus “sticky
,” from Latin viscum “anything sticky, birdlime made from mistletoe, mistletoe,” probably from PIE root *weis- “to melt away, flow” (used of foul or malodorous fluids); see virus.
Does viscous mean thick?
It is commonly perceived as “thickness”,
or resistance to pouring
. 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.
Which liquid has highest viscosity?
One of the most viscous liquids known is
pitch, also known as bitumen, asphalt, or tar
. Demonstrating its flow and measuring its viscosity is the subject of the longest continuously running scientific experiment, begun in 1927 at the University of Queensland in Australia.

What is highly viscous?
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. … Honey would move slower than water, so honey would have a greater viscosity.
