A real liquid does not exhibit laminar flow at the inner wall of a pipe due to the presence of viscosity and turbulence caused by interactions with the pipe surface and other layers of fluid. As the liquid flows, friction between the fluid layers and the pipe wall can induce shear stress, leading to disturbances that disrupt the orderly flow patterns characteristic of laminar flow. Additionally, any imperfections or roughness on the pipe wall can further contribute to turbulence and transition to a more chaotic flow regime. Therefore, while laminar flow can occur in ideal conditions, real liquids often experience a mix of flow patterns influenced by these factors.

What are flow patterns around a stationary object in laminar flow?
This question is its own answer. The flow patterns in laminar flow are laminar.
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.
When was Laminar Flow - album - created?
Laminar Flow - album - was created in 1979.
What is the effect that radius changes have on the laminar flow of a fluid?
Increasing the radius of a pipe where laminar flow occurs typically leads to a decrease in the flow velocity needed to maintain laminar flow. This is because the flow rate is proportional to the radius to the power of four in laminar flow conditions. As a result, larger radii usually allow for higher flow rates while still maintaining laminar flow.
What can be used to define laminar flow?
Laminar flow can be defined by the help of Reynold's number that can be determined by conducting experiments. A Reynold number <=2000 indicates that the flow is laminar.
What is the translation from laminar to turbulent flow?
Laminar flow refers to smooth, orderly flow with predictable patterns, while turbulent flow is characterized by chaotic, irregular movement with swirling vortices and mixing. The transition from laminar to turbulent flow occurs when the flow speed or viscosity of the fluid increases, leading to the breakdown of laminar layers and the onset of turbulence.
What is the assumption of steady flow process?
Flow is Laminar.
How is turbulent flow different from laminar flow?

What measure will cause a laminar flow to become turbulent?
Increasing the velocity of the fluid will cause a laminar flow to become turbulent.
The red liquid level of the manometer on laminar airflow indicates what?
The red liquid level of the manometer on laminar airflow indicates the pressure difference between the two points of the airflow system being measured. This pressure difference helps determine the flow rate of the airflow.
What are the differences between horizontal and vertical laminar flow hoods?
In a horizontal laminar flow hood, the laminar air flows towards the outside (i.e. towards the worker). There is hence no protection to the worker and it is not suitable for cytotoxic drug preparation. In a vertical laminar flow hood, the laminar air flows downwards from the top, providing more protection for the workers. Vertical laminar flow hoods are hence suitable for preparing cytotoxic drugs.
