My intention in providing the plans is really just to give people and idea of how to build a tube, rather than intend them to follow them exactly - in otherwords they are for 'information only'
If you build a tube to my plans, it will work, at least in principle! However please note the following.
The tubes in the plans were designed for a research project that investigated the flow within them (amongst other things). For this reason, the tubes were of fairly large diameter, so that probes etc could be inserted without disturbing the flow too much.
Large diameter tubes need a bigger flow rate (and pressure) than small diameter tubes. For me this was not a problem, as we had very large room-sized compressor to power the tubes.
If, however, you're planning to use a small compressor, then you might well run into problems. I would suggest, therefore, that you make a much smaller diameter tube - as small as you can manage. The smallest commercial ones are tiny (around 4-5mm diameter). Scaling down my plans to this sort of size should work (although obviously I can't give any gaurentees as I haven't actually tried this)
I cannot under any circumstances accept any liability whatsoever for the consequences of any function or failure to function of the device described in these plans.
Nor can I undertake to answer questions about these plans, or offer any help in their realisation. Feel free to email me, but I cannot promise that I'll reply. If you keep your question short and specific, then you're more likely to hear something
