A few years ago Hackaday featured a laminar project ... in parallel inside a 4″ PVC pipe. The water input is a 3/4″ garden hose adapter, perpendicular to the flow of the output nozzle.

Now, instead of using water in your pipes, replace it with honey. Assuming you could provide a large enough pressure, even for fast flow the motion would remain laminar. If you do not wish to do this ...

clear pipe to observe its movement. His experiments showed that as the input water velocity increased, the flow went from laminar (smooth and predictable) to turbulent (unsteady and unpredictable ...

IHI Corporation (TOKYO:7013) is proud to announce the successful development and world-first testing of a cutting-edge vacuum pump designed for hybrid laminar flow control (HLFC) systems.
