For example, water does not wet waxed surfaces or many plastics such as polyethylene. The viscosity of some familiar liquids are given in Table 1.5.1. We can perceive relative viscocity with our senses. If the adhesive forces between water molecules and the molecules of the surface are weak compared to the cohesive forces between the water molecules, the water does not “wet” the surface. Examples of high viscosity: honey, lava, molaces, corn syrup Remember that viscocity is a measurement of a liquids resistence to flow. Consider what happens when water comes into contact with some surface. Alcohols, such as ethanol, also have low. Water is often used in cooling systems, heating systems and other applications where free-flowing fluids are required. Napa oils are undoubtedly one of the best oil that you can use on. Examples of low viscosity liquids include water, alcohols and some oils. In general, fully synthetic motor oils contain non-conventional, high-performance fluids. For example, in the case of glycerolOhis increased to 2, and by mixing both fluids a wide range of different scaling behaviour can be explored. The IMFs of attraction between two different molecules are called adhesive forces. In contrast, high viscosity liquids are often thicker, more difficult to handle and require more energy to move. for example linear polymer solution and other polymeric liquids. \): Surface tension (right) prevents this insect, a “water strider,” from sinking into the water. Atomization of high-viscosity fluids, such as heavy oil, is technically challenging.
