26 cze 2023 · Liquids whose molecules are polar or can form hydrogen bonds are usually more viscous than similar nonpolar substances. Honey, mostly glucose and fructose (see image below) is a good example of a liquid which owes its viscosity to hydrogen bonding.

5 dni temu · Examples are water, mineral oil, alcohol, and gasoline. On the other hand, if the viscosity does not remain constant and depends on the force applied, the fluid is called non-Newtonian fluid. The viscosity changes as shear stress is applied. Examples include slime, toothpaste, cosmetics, and paints.
In industrial practice, viscosities of solutions (meaning homogeneous products of dissolution of solids or gases in liquids) and fluid mixtures (meaning homogeneous mixtures resulting out of mixing of two or more
30 sty 2023 · Viscosity can be not only a fluid’s resistance to flow but also a gas’ resistance to flow, change shape or movement. The opposite of viscosity is fluidity which measures the ease of flow while liquids such as motor oil or honey which are “sluggish” and high in viscosity are known as viscous.
In industrial practice, viscosities of solutions (meaning homogeneous products of dissolution of solids or gases in liquids) and fluid mixtures (meaning homogeneous mixtures resulting out of mixing of two or more fluids) are often needed for the design of the different unit operations and processes involved.
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. [1] For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. [2] Viscosity is defined scientifically as a force multiplied by a time divided by an area.
17 lut 2023 · A homogeneous mixture is one that contains the same proportions of its components in a given amount of sample. Homogeneous mixtures might be solid, liquid, or gas. All of them share the same physical attributes and chemical composition.
