Not easily, I'm afraid. There are online calculators out there, http://airfoiltools.com/calculator/reynoldsnumber for instance but you would have to do some research for some of the input data.yes u r right.
is it possible to get accurate reynolds number for this device?
Just to me broken image?No problem! As promised from our PM, here are the sketchup pics.Thanks again I really appreciate learning from you, that really helps me understand the science behind this wonderful build. I would love to see the mods sticky this thread, this is really next level type stuff.

The water drip is really difficult to to deal with. When more fog is pushed through, the drip gets worse. I am still trying to figure out a good way to combat that. Adding a drip channel helped a lot. So, what I have going on is; in the fog chamber, where the fog gets funneled down to the straws, there is a small aluminum channel that works like a drip tray. It's mounted at an incline so gravity moves the water to a drain hose. This channel is mounted on the side of the chamber where the fog enters. You can see the drip channel in one of my previous pictures.another problem!
the water drop...
how can I prevent it?
where did u buy it? any links?Let's start with the honeycomb. So, after procuring aluminum honeycomb (not as easy a task as it sounds) It needed to be cut, expanded and trimmed to size. Of course, going into this, I didn't know how to do any of it! Cutting was the most physically demanding part but didn't taking much figuring to do it. Expanding it was a pretty daunting task. After trying to look up the procedure for expanding honeycomb, I became a little despondent. Commercially expanded honeycomb required a special expander to do the job right. I finally had to look up one of these devices to see how they worked. Now, I could have ordered the honeycomb expanded and cut to size but due to the fragility of aluminum honeycomb, the shipping costs (which were already high for the unexpanded) would have been astronomical. It probably would have added another $200~$300 to the shipping. Well, after learning how the honeycomb expanders worked, I figured out how to make my own "expander"
So, there it is... 120lbs worth of unexpanded aluminum honeycomb. Solid as a brick!

After several hours of cutting with a hack saw, I sliced off the piece I needed.

...And now for the expansion!

After expanding, cleaving was easy. Just a sharp kitchen knife and some patience

Not really. I just wanted kids to be able to walk through it and the only way that would be possible is down flow from above.It seems as you started with an UP flow version first and then went to an above mounted DOWN flow version. I was wondering if you had any specific issue with the UP flow version? I understand that the DOWN flow version probably works better, but would you recommend building one if up flow is the only realistic option.
Thanks!I am not sure how he did it, but I have used the below item in the past and 12VDC computer fans. You should be able to put multiple fans on one channel, just make sure the fans can be controlled by varying the voltage (most DC fans are like this) and don't exceed the current capacity of that channel. I personally keep it to 80% of the total ampacity. Motors you would have to decrease that percentage dramatically due to start up ampacity, but with fans you should be okay.
Dear absolom7691,After getting a few inquiries about set-up, I decided to put up a new video showing out I set this thing up.
