An air plane wing or anything that reduces drag like an arrow,dart, or even fish. Other examples could be the fins of dolphins, blood through arteries, water in a tube. Just remember that laminar flow is flow in which the fluid flows smoothly without much resistance. The fluid pretty much travels in straight or almost straight lines.

PRINCIPAL- Laminar Air Flow is based on the flow of air current to create uniform velocity, along parallel lines, which helps in transforming microbial culture in aseptic conditions .

∙ 15y agoThe word "laminar" refers to a type of flow. The opposite of laminar is "turbulent". For example, rivers with smooth, sandy bottoms will have a smooth or laminar flow. Rivers with rocky, rougher bottoms will have turbulent flow which is a disorganisation of the liquid. This is what you see in rapids. An every day example is when you empty a bottle of water with a small mouth, you notice that you can empty it faster if you don't tilt it as much; this is laminar flow. If you put the bottle upside down, it empties slower because of turbulence in the water. Turbulent and laminar flows can occur in any liquid or gas.

∙ 11y agoThe turbulence of a fluid is measured with the dimensionless quantity known as the Reynolds Number (often abbreviated NRe). The Reynolds number is the ratio of inertial forces to viscous forces and is represented by the equation:
NRe = D * V * ρ / μ
where D= Diameter of the pipe, V= velocity of the fluid, ρ= density of the fluid, and μ= viscosity of the fluid.
Reynolds numbers above 2000 are considered turbulent and those less than that are considered laminar. Therefore a higher viscosity (μ) results in a lower Reynolds number (NRe ) because viscous forces are dominating inertial forces.

What is the translation from laminar to turbulent flow?
laminar =viscosity drops intertaily motion Turbulent = intertia dominates motion.
What is the difference between laminar and turbulent flame patterns?
In laminar flow, easy to define the burning velocity, independent of the measuring apparatus within reasonable limits whereas not possible to turbulent flow.
Is flow in a Venturi tube laminar or turbulent?
In laminar flow, air resistance is proportional to velocity of the body whereas in turbulent flow, air resistance is proportional to (velocity)2.
Steady flow and non steady examples?
Steady flow: laminar flow over a sphere. Unsteady flow: turbulent flow over anything.
Would you prefer turbulent flow or laminar flow for whitewater rafting?
As we know, whitewater rafting is in water, in which turbulent flow would be best in the case. Generally because the water will NOT be straight, and this activity is where the water flow is rather rough then smooth. Overall, turbulent flow is best used in this scenario.
How is turbulent flow different from laminar flow?

Why is no obstruction important for air flow techniques?
The laminar flow hood depends on the laminar air flow to sweep away pathogens from the hood. If there is obstruction, the laminar air flow pattern will be disrupted. The laminar air flow will then change to turbulent air flow.

Why you determine reynold number in fluid mechanics?
Reynolds number tells you what the flow is doing. A Reynolds number of 0-2000 is laminar flow 2000-4000 is the transition (where both laminar and turbulent flow is possible) 4000+ is fully turbulent flow
Why poiseuille equation not applied to turbulent flow?
Coz poiseuille eq is for poiseuille flow, which is a laminar flow, not turbulent flow. And it also need to be a fully developed , pressure driven flow.
Would you prefer turbulent flow or laminar flow around a racing bicycleWhich would you like for whitewater rafting?
You want laminar around a bicycle for less resistance, but turbulent in rafting so that you get all of the white water
What are examples of turbulent flow?
Smoke rising from a flame. At first the smoke rises with laminar flow before becoming turbulent just a few centimetres above the source.
Steady flow and non steady examples?
Steady flow: laminar flow over a sphere. Unsteady flow: turbulent flow over anything.
How can we relates the Reynolds Number with the phenomena of turbulence and laminar?
Turbulent flow occurs above a certain Reynold's number; laminar flow occurs below a certain Reynold's number. The exact value of the Reynold's number required for flow to become turbulent varies, depending on the specific situation.
What are disadvantages and advantages of turbulent flow?
Advantage: objects in a turbulent flow experience less drag. Disadvantage: turbulent flows are unstable meaning velocity and pressures change rapidly. The objects in the flow have less stability. The flow also is more difficult to model then a laminar flow.
