Poiseuille flow is a laminar flow characterized by the continuous transport of fluid due to a pressure difference between two regions. It is commonly observed in situations where there is a significant difference in the viscosity of the fluid in the flow between two regions.
In a pipe, Poiseuille flow occurs when a pressure difference is applied across the pipe's diameter. This pressure difference causes fluid to flow from the region with higher pressure to the region with lower pressure. The flow is characterized by a smooth and continuous boundary, with no turbulence.
The flow velocity in Poiseuille flow is proportional to the pressure difference and inversely proportional to the pipe diameter. This means that the flow velocity is higher in a pipe with a smaller diameter, and it is lower in a pipe with a larger diameter.
Poiseuille flow is a common example of a laminar flow, which are flows that are characterized by a constant velocity profile. Laminar flow occurs when the flow is laminar, meaning that it appears smooth and continuous to a observer.
Here's a simple analogy to help visualize Poiseuille flow:
Imagine a water bottle filled with water. If you slowly pour water from the top of the bottle to the bottom, the water will flow smoothly down the neck of the bottle. This is an example of Poiseuille flow
