Question

Why is it important in our lives? Give examples. 5 stars 4 it

Answer 1

in addition to howard&#039;s answer... seriously, what if peeing took longer than p**p!!

Answer 2

Parenthood

Answer 3

In very, very simple terms, viscosity is the resistance of a fluid to flow.

It is important because different liquids are used for different pusposes in daily life; and different viscosities make different fluids suitable for those purposes:

Examples:

1.- Lubricating oil for internal combustion engines:

Engines use lower viscosity oil in areas with very low temepratures; since the oil&#039;s viscosity is affected by temperature. Also, a car with gih mileage works better with a higher viscosity oil.

2.- Paint; if the viscosity is too high, you cannot apply the paint properly with a paintbrush it&#039;s hard to extend it over the surface to be covered; if it&#039;s too low, the paint will just flow down and won&#039;t stay on the surface you are painting.

3.- The human body: all body fluids are based on water. How would the human body work if the water had a viscosity as high as that of crude oil ?

Answer 4

http://en.wikipedia.org/wiki/Viscosity

Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or extensional stress. In general terms it is the resistance of a liquid to flow, or its &quot;thickness&quot;. Viscosity describes a fluid&#039;s internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is &quot;thin&quot;, having a lower viscosity, while vegetable oil is &quot;thick&quot; having a higher viscosity.

Viscosity = lubrication.  Without that machines wouldn&#039;t run, cars wouldn&#039;t work, and your blood wouldn&#039;t run through your body.

Answer 5

When I rub oil over my body I like the Viscous feeling it has on me...and that is important!

Answer 6

The &quot;thickness&quot; of a liquid or its ability to flow. Most liquids decrease in viscosity and flow more easily as they get warmer.

www.coleparmer.com/techinfo/techinfo.a...

The resistance of fluids to flow, due to internal forces and friction between molecules, which increases as its temperature decreases.

www.poorjohns.com/Plumbing_Glossary.ht...

The resistance of fluid to flow. A high viscosity fluid will not flow as easily as a low viscosity fluid (Mud will not move as easily as water).

Measure of the fluidity of a substance. Taffy and molasses are very viscous; water has low viscosity.

interactive2.er.usgs.gov/learningweb/t...

Measure of the internal friction or resistance of an oil to flow. As the temperature of an oil is increased, its viscosity decreases and it is therefore able to flow more readily. Viscosity is measured on several different scales, including Redwood No. ...

The state of being viscous; (physics) A quantity expressing the magnitude of internal friction in a fluid, as measured by the force per unit area resisting uniform flow

(1)Motor oil needs high viscosity to lubricate an engine.

(2)its how thick it is like catchup

(3) the diffrence in how water flows veres oil

(4)Taffy and molasses are very viscous; water has low viscosity.

(5)Mud will not move as easily as water

Answer 7

Viscosity is the thickness of a liquid.

Example: Water&#039;s viscosity is much lower than that of, say, motor oil.

I think the only importance it has  in our lives and understanding the world around and being able to explain situations better.

Answer 8

Viscosity is the resistance to flow. The higher the viscosity, the slower the flow. Oil has a high viscosity. Imagine if your car&#039;s engine oil were as thin as water: it would immediately run down into the oil pan and the engine parts would never get lubricated, burning up your engine in no time! Or can you imagine how long it would take to flush a toilet if water were as thick as motor oil? Clearly we need fluids of widely varying viscosities to live our lives!
