Viscosity can be of critical importance in medicine as fluids are introduced into the body intravenously. viscosity synonyms, viscosity pronunciation, viscosity translation, English dictionary definition of viscosity. Lubricants that are too thin provide too little protection for moving parts. Lubricants that are too viscous can jam and clog pipelines. Manufacturing equipment requires appropriate lubrication to run smoothly. Some viscous fluids add texture to foods honey, for example, is quite viscous and can change the "mouth feel" of a dish. Temperature will affect the viscosity of most materials. What is the definition of viscosity The viscosity describes the thickness or pourability of a fluid and enables the comparison of the fluidity of two different. A thick potato and leek soup, for example, when it is less viscous, becomes French vichyssoise. The higher the viscosity of a liquid, the thicker it is and the greater the resistance to flow. Different cuisines also rely on the viscosity of sauces, soups, and stews. Fats, which are moderately viscous when heated, become solid when chilled. Cooking oils may or may not change viscosity as they heat, while many become much more viscous as they cool. Viscosity plays a significant role in the preparation and serving of food.

A fluid may be made up of molecules that vary in size, shape, and cohesiveness or a single type of molecule. Brookfield 'thixotropic index' for gelcoats: The ratio of RV4 spindle viscosity at 4rpm to 20rpm at 25C. Viscosity is a measure of a fluid’s internal friction (resistance to flow) when one layer of fluid is forced to move in over another layer. Viscosity of gel-coats: Brookfield RV viscometer, spindle 4 at 4rpm, 25C. Some oils have a more stable viscosity, while others react to heat or cold if your oil's viscosity index is low, it may become thinner as it heats, which can cause problems as you operate your car on a hot summer's day. Viscosity of resin for plastisols: Brookfield LVT or equivalent, spindle 3 at 12 rpm, temperature 25, measure viscosity after 60s.

In addition, viscosity also affects the rate of oil consumption and the ease with which your vehicle will start in hot or cold conditions. That's because viscosity affects friction, and friction, in turn, affects heat. When you put oil into your car or truck, you should be aware of its viscosity.
