Laminar flow is the type of flow in which the fluid moves smoothly or in a regular path from one layer to the next. Kinematic viscosity is more useful than dynamic viscosity. It can be computed by dividing the dynamic viscosity of the fluid by fluid mass density. It can be referred to as the ratio between the dynamic viscosity and density of the fluid. In kinematic viscosity, there is no force involved. Dynamic viscosity is used to calculate the rate of flow in liquid. It is defined as the ratio of shear stress to the shear strain of the motion. When the viscosity is measured directly by measuring force. Types of viscosity are: Dynamic Viscosity Measuring the viscosity of any matter helps in determining and designing the production and transportation procedure. For example, if the viscosity of toothpaste is not appropriate it will either be very difficult to pump out the toothpaste or a lot of toothpaste will be pumped out in one go. Viscosity of a given matter is calculated in order to measure the behaviour of the matter in the actual world. The higher the viscosity the slower the flow of liquid. But if the oil is replaced with honey, to move the same plate with the same velocity more force will be required as the friction and resistance will be high in the case of honey. Blood viscosity is a major issue: blood that is too viscous can form dangerous internal clots, while blood that is too thin will not clot this can lead to dangerous blood loss and even death.If we take a fluid like oil and place it between the two plates, where the bottom plate is fixed at one place and the top plate is moved with a constant velocity relative to the fixed place the resistance will be low and the oil will move easily. 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. Manufacturing equipment requires appropriate lubrication to run smoothly. 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. In this regard, mounting fluorescence probes are being increasingly fabricated to map viscosity inside live cells and small animals. However, owing to the complicated character, it is still a huge challenge to directly observe viscosity in living systems. 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. Recently, precise visualization of viscosity has started to arouse more and more interest. 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.
