On the other hand, the kinematic viscosity tells about the speed the fluid reaches when a particular force is applied to the fluid. When choosing between the two viscosities, it is worth noting that dynamic viscosity tells us about the force required to move the fluid at a certain speed. The larger the force or stress needed to move the plate, the more viscous the fluid is. Dynamic viscosity, or the absolute viscosity of water, or any fluid, is proportional to the tangential shear stress per unit area needed to move one plate at a constant speed over another plate at a maintained fluid thickness between these two plates, like in a Couette flow, as shown below: When dealing with viscosities, when we mention "viscosity," we actually mean dynamic viscosity. In this article, we'll focus more on the viscosity of liquids, specifically on the kinematic viscosity and the dynamic viscosity of water. This weakening results in liquid molecules to move more freely and, therefore, with a lower viscosity. In liquids, when molecules start to move faster, their attraction from each other weakens. As a result, in gases, molecules experience more friction against each other, making them flow slower and become viscous. However, when we apply heat or additional thermal energy to our fluids, their molecules start moving faster.

The attraction between the molecules of a viscous fluid is much higher than that of a less viscous fluid. We can also express viscosity as the internal friction of a fluid in motion.

Maple syrup, a very viscous fluid, would pour slower than when you pour milk on your cereal as milk's viscosity is much lower. Imagine dripping maple syrup on your waffles for your breakfast. The higher the viscosity of a fluid (liquid or gas), the slower it traverses across a surface. So, the resistance force against the flow by water will be less as compared to honey.Viscosity is the measure of a fluid's resistance to flow. Among, the two fluids, water, and honey, honey has high viscosity as compared to water. Let’s describe the term high-viscosity with an example. The fluid with high viscosity offers greater flow resistance. High viscosity usually means the liquid is thicker. Blood circulation inside our body depends on the viscosity of blood.Gums, coolants, petrol as a cleaner, brake fluid, cosmetics, food products, etc all require viscosity data during production to work smoothly.Cooking oils, fats, butter, etc are manufactured providing a specific viscosity.
