7/14/2023 0 Comments Honey viscosity![]() The key is to select a fluid with a viscosity that is not too low or too high. Using lubricants with too high a viscosity for the application may lead to the following issues: Using lubricants with inadequate viscosity for the application may lead to the following issues: However, use of a fluid with a higher-than recommended viscosity can be just as detrimental as using an oil whose viscosity is too low. Knowing that a fluid’s viscosity is directly related to its ability to carry a load, one would think that the more viscous a fluid, the better it is. Requirements for gasoline and diesel motor oils have been set forth in the SAE J-300 Engine Oils Viscosity Classification and the American Petroleum Institute (API) Service Classification. A viscosity that’s too high can cause heat, increased energy consumption and a lack of lubrication as the fluid may not be able to pass through small passages as readily.Ī lubricant’s viscosity range is often reported by using a grading system such as those established by the Society of Automotive Engineers (SAE) or the International Organization for Standardization (ISO). If viscosity is too low, friction between mating components generates heat and excessive wear. Viscosity is an important characteristic to consider when determining which fluid is most suitable for an application. How the viscosity of a fluid reacts to changes in temperature, pressure or speed determines how well a fluid can perform the basic functions of a lubricant. The greater the internal friction, the higher the viscosity of the fluid. What causes that difference? When external forces such as gravity act on a fluid, the molecules within the fluid begin to move against each other, resulting in molecular-level friction that resists flow. The contrast is due to their different viscosities. Water runs fast and easy while honey flows thick and slow. To help visualize the differences in viscosity properties, think about how honey and water flow when poured. ![]() Of the fundamental physical properties, viscosity – the measure of the internal friction of a liquid, or its resistance to flow – is one of the most critical. ![]() Lubrication science seeks to optimize a lubricant’s performance by managing these properties through use of different base oils and additives. The physical properties of lubricants include important characteristics like viscosity, shear stability, high- and low temperature performance, water resistance and volatility.
