Difference between laminar flow and turbulent flow

Main Difference

Physics is a vast field and there are many subjects that are difficult to understand for people who are not directly related to the field. One of the main focuses of physics belongs to the flow of liquids. This flow has many properties and becomes an essential part of various industrial processes. In the manufacturing industry, different types of fluids are used to operate machines and processes that require the flow of some type of liquid substance and two terms that are very important in this sense are known as Laminar Flow and Turbulent Flow. There are many differences between them, the similarities are only insofar as both processes are related to the flow of liquids, the differences between them will be discussed in this article. Since pipes are used to aid fluid flow, the definitions of both terms are directly related. Therefore, laminar flow is defined as fluid flow in which each part of the fluids follows a similar path smoothly and the path is so clear that there is no interference. Turbulent flow, then it becomes the opposite of laminar flow, in this the flow is irregular and there are always some distractions when the liquid is flowing. Another difference between these two types of flows is that the velocity is constant at all points in a laminar flow, while the velocity changes in different instances in a turbulent flow. The best example of both flows may be a running water pipe for plants. When the water flows through the pipe, The flow is supposed to be laminar, while the flow becomes turbulent when the water reaches the outside point of the pipe and is pressured by the person who is watering the plants. The water spreads to cover more area but the flow becomes erratic. Another difference between the flows is that the laminar flow is maximum in the center while the rate becomes low in the extremes. In the case of turbulent flow, the flow rate is highest at the extremes while it is slowest in the middle. Another difference between the flows is that the laminar flow is maximum in the center while the rate becomes low in the extremes. In the case of turbulent flow, the flow rate is highest at the extremes while it is slowest in the middle. Another difference between the flows is that the laminar flow is maximum in the center while the rate becomes low in the extremes. In the case of turbulent flow, the flow rate is highest at the extremes while it is slowest in the middle.

Definition of laminar flow

When a person smokes a cigarette, smoke comes out. If a careful observation is made it can be seen that the smoke is not irregular and follows a similar trajectory, this is known as laminar flow. One, where the fluid follows a straight path and there are no distractions in the flow, this may be possible in industry using another fluid that keeps the surface of the pipes smooth. The velocity is constant at all points in a laminar flow and the flow peaks in the middle and slows down when it reaches the end surfaces.

Definition of turbulent flow

Once cigarette smoke goes out after following a straight path for some time, it tends to oscillate at a particular point, this becomes a turbulent flow. One, in which there is no smoothness in the way the fluid flows and pipes that are used in industry have rough surfaces. This flow can be useful in some applications, but is mostly considered inefficient. The speed changes every instant in the turbulent flow while having the maximum rate at the end, the rate is slower in the central region due to many irregularities.

Differences in a nutshell

  1. Laminar flow occurs in pipes that do not have uneven surfaces and turbulent flow occurs in pipes where there is roughness.
  2. Laminar flow is defined as flow that runs smoothly while turbulent flow is defined as one that is irregular in the way it moves.
  3. The speed is the same throughout a laminar flow, while it varies when the flow is turbulent.
  4. Laminar flow is maximum in the middle while decreasing at the end. In turbulent flow, the case is the opposite where the flow is maximum at the ends but less at the center.
  5. Laminar flow has a low flow rate, while turbulent flow has a higher rate.
  6. Flow is considered to be optimized in laminar, whereas it is considered not optimized in turbulent.

Final Thought

In general, it can be said that the two most famous terms are very different from each other. Flows can be an important part of the topic. Therefore, whoever wants to know more about them realizes that they belong to a category. This article makes sure you can find out what exactly it is.
