Viscosity can be of critical importance in medicine as fluids are introduced into the body intravenously. Lubricants that are too thin provide too little protection for moving parts. Lubricants that are too viscous can jam and clog pipelines. Introduzione Sono trascorsi ormai alcuni decenni da quando Bingham, nel 1929, ha fondato in modo ufficiale la branca della meccanica dei fluidi nota come reologia. Manufacturing equipment requires appropriate lubrication to run smoothly. Keywords polymers, viscosity, elasticity, instability, processability 1. Some viscous fluids add texture to foods honey, for example, is quite viscous and can change the "mouth feel" of a dish. A thick potato and leek soup, for example, when it is less viscous, becomes French vichyssoise. 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. 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. 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. In the field of materials science, for example, viscosity is used to describe the flow behavior of polymers and other complex fluids. Viscosity a measure of a fluid’s resistance to flow is an important property of liquid and semi-liquid products that can be used for both process and product-quality control. ![]() Viscosity is an important property in many fields, including engineering, physics, and biology, and it is used to describe a wide range of fluids, including liquids, gases, and even some solids. The viscosity of a fluid is typically measured using a device called a viscometer, which applies a shear force to the fluid and measures the resulting shear stress. For example, honey has a high viscosity and flows slowly, while water has a low viscosity and flows quickly. Viscosity measurements are made in conjunction with product quality and efficiency. ![]() Brookfield deals with liquids and semi-solids. ![]() Viscosity is a principal parameter when any flow measurements of fluids, such as liquids, semi-solids, gases and even solids are made. The viscosity of a fluid can vary depending on a number of factors, such as temperature, pressure, and the presence of other substances.

The ideal fluid has constant density and is incompressible has constant pressure, acting equally in all directions is non-viscous meaning that it has no. In other words, viscosity describes how “thick” or “thin” a fluid is and how easily it flows. It is a dimensionless quantity that is defined as the ratio of shear stress to shear rate, or the force required to move one layer of a fluid past another layer, divided by the rate at which that force is applied. ![]() Viscosity is a measure of the thickness or resistance to flow of a liquid or a fluid. ![]()
