Česká republika, Čeština (Czech Republic).Some people also know it with the adjective”thickness”, although its real name is viscosity. Viscosity is a measure of resistance to deformations caused by tensile stresses or shear stresses. The 10 Most Known Viscosity Examples Some Examples of viscosity Or viscous substances are: honey, oil, toothpaste and some chemical elements such as mercury. Which is the best example of viscosity in the world? A less viscous fluid will produce lesser shear on a body as it flows, while more viscous would produce more. Viscosity is something that grants the fluid the ability to cause friction (drag). If air flows over your hand, you feel less force than when water flows. What is the difference between viscosity and force? An example of a high viscosity liquid is syrup. Low viscosity refers to substances that are thin, such as water, while high viscosity substances are thick. The difference between high and low viscosity is the thickness of the material being measured. What is the difference between high and low viscosity? The type of matter a fluid is made of is the main determiner of how viscous it is, though other factors, including temperature, will also affect viscosity. What makes a fluid more viscous or less viscous?Ī more viscous fluid will have a higher value in terms of millipascal seconds, while a less viscous fluid will have a smaller value. Liquids like water have a much lower viscosity compared to liquids such as honey. High viscosity means that the thickness of the material is very thick compared to low viscosity which is rather thin. Liquids containing long molecules are invariably very viscous. Liquids whose molecules are polar or can form hydrogen bonds are usually more viscous than similar nonpolar substances. Viscosity is governed by the strength of intermolecular forces and especially by the shapes of the molecules of a liquid. The other number indicates the oil’s resistance to thinning at high temperatures. Is 5W or 10W thicker?Ī 10W or 5W is the index for how easily the oil flows in winter (hence the W). Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life. Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. viscosity is how smoothly a liquid flows and how hardly the liquid flows it is highly viscous. The liquid with the most intermolecular force is high viscous. Water molecules are very cohesive because of the molecule’s polarity.Įxplanation: Here Oil is the most viscous liquid. We normally think of liquids like honey or motor oil being viscous, but when compared to other substances with like structures, water is viscous. Viscosity is the property of fluid having high resistance to flow. Thus, water is “thin”, having a low viscosity, while vegetable oil is “thick” having a high viscosity. Viscosity describes a fluid’s internal resistance to flow and may be thought of as a measure of fluid friction. ![]() A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion. Viscosity is a measure of a fluid’s resistance to flow. Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly high viscosity fluids move sluggishly and resist deformation. What is the difference between low viscosity and high viscosity?Īccording to Wikipedia, viscosity is the friction between the molecules of fluid. Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads. Thin oils reduce friction in engines and help engines start quickly during cold weather. Thin oils have lower viscosity and pour more easily at low temperatures than thicker oils that have a higher viscosity. The higher the viscosity of a liquid, the thicker it is and the greater the resistance to flow. To think of viscosity in everyday terms, the easier a fluid moves, the lower the viscosity. A fluid that is highly viscous has a high resistance (like having more friction) and flows slower than a low-viscosity fluid. Viscosity is the measure of resistance of a fluid to flow. What does it mean if something is more viscous less viscous?
