Pipe flow refers to the movement of fluids within fully enclosed conduits, typically cylindrical in shape, such as water pipes or hydraulic hoses. These conduits are designed to withstand high-pressure gradients that drive fluid movement, contrasting with open-channel flows, where gravity is the primary driving force. Rectangular conduits, like air conditioning and heating ducts, generally operate at lower pressures and are less suited for high-pressure applications. The classification of fluid...

When fluid enters a pipe, it first passes through the entrance region, where the velocity profile adjusts due to viscous effects. In this region, a boundary layer forms along the pipe walls and grows until it fully occupies the pipe's cross-section. Once the boundary layer merges, the flow becomes fully developed, with a steady velocity profile that remains consistent along the pipe's length. The distance to reach a fully developed flow is called the entrance length and depends on the flow...

Understanding fluid flow behavior through pipes is critical in fluid mechanics, especially in applications like oil transportation through pipelines. Hagen-Poiseuille's law provides an exact solution derived from the Navier-Stokes equations for steady, incompressible, and laminar flow within a circular pipe. Hagen-Poiseuille's law helps determine the necessary pressure drop across a pipeline section by determining parameters like pipe length, radius, oil viscosity, and the desired volumetric...

Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana The objective of this video is to describe recent advancements of computational fluid dynamic (CFD) simulations based on patient- or animal-specific vasculature. Here, subject-based vessel segmentations were created, and, using a combination of open-source and commercial tools, a high-resolution numerical solution was determined within a flow model.

Source: Alexander S Rattner, Department of Mechanical and Nuclear Engineering, The Pennsylvania State University, University Park, PA This experiment introduces the measurement and modeling of pressure losses in piping networks and internal flow systems. In such systems, frictional flow resistance from channel walls, fittings, and obstructions causes mechanical energy in the form of fluid pressure to be converted to heat. Engineering analyses are needed to size flow hardware to ensure...
FAQs
The design of the model determines which structural features and interactions learners can observe. Bending, joining, separating, or rearranging pieces makes changes in form visible, allowing students to discuss how altered arrangements may influence function. This connection helps translate an abstract biological process into a physical sequence that can be examined and explained.
These manipulations represent different kinds of structural change, depending on the biological process being modeled. Joining can show components becoming connected, separation can track components moving apart, and bending can represent changes in shape or arrangement. Their meaning is not fixed, so the activity must be designed with a clear biological correspondence between each action and the process under study.
A physical model highlights selected relationships rather than every feature of a biological system. The choice of pieces, connections, and permitted movements determines what learners can track and what remains outside the model. Explicitly discussing those choices helps students interpret the representation appropriately and avoid treating a simplified structure as the complete biological process.
Rearranging components creates a visible record of change across a sequence of events. Learners can compare starting and ending arrangements, identify patterns, and discuss how structural differences relate to biological outcomes. This is especially useful when the original process is difficult to see directly, because the model provides a shared object for observation, explanation, and interpretation.
Begin by selecting the biological structure or process to represent, then assign pipe cleaners to its relevant components. Arrange the pieces to show an initial state, perform the planned bending, joining, separating, or rearranging actions, and compare the resulting arrangement with the starting one. Discussion afterward connects the observed changes to the intended biological concept.
The activity requires flexible pipe cleaners and a model design that identifies what each piece represents and how it may be manipulated. Its low-cost format makes it suitable for hands-on learning, while the biological meaning depends on clear instructions and purposeful arrangements. The same basic materials can support models of cells, chromosomes, molecules, or organismal form.
It can support lessons on heredity, cell division, molecular structure, and organismal form. In each case, the model gives learners a way to handle components, observe structural changes, and connect those changes with biological ideas. The specific application depends on how the pipe cleaners are assigned and arranged for the topic being taught.
Students can identify patterns, track interactions among represented components, and explain how structural changes relate to biological processes. The activity also encourages discussion about experimental interpretation, because learners must connect a physical arrangement with the concept it represents. These outcomes make the exercise useful for linking active manipulation with biological reasoning rather than relying only on verbal description.
