Hello
Why not use this:
http://www.pressure-drop.com/div/shot.html

there are the calculations all done, even if they are only theoretical

we can download and try this software 4 weeks

with pressure-drop, you can calculate the pressure drop caused by a reactor by choosing "circular pipe", which thermexel does not have (you have to reprogram inside your software, I asked it, and again, it was necessary to calculate the perimeter of the passage section, undoubtedly feasible since its software is not blocked, but when we can have done everything, and in addition online)

for the venturi, you still have to download the trial version (see above)

If not for an online venturi calculation, there is also this:
(you have to go down to "connections", then click on"calculations, curving baseballs and wings"
the hardest thing is to know the values ​​of viscosity, density, etc. putting the comma in the right place:

Hello
I prepared a little video, because I love it : Cheesy: just to make a small comparison on and without venturi.
I must say that it is quite spectacular :P (Almost a Hollywood blockbuster :D )

Nice your experience and your video Pitmix !! Too bad we can not see the inside of your air intake tube. A tip for that: Frame only inside the tube so that the camcorder's photo cell only measures the light on the inside of the tube. Otherwise, if you film the tube with a lighter background around, the cell will make an average measurement and the inside of the tube will necessarily be dark. If you manage to solve this little problem, you're good for Hollyvoud!

Yeah but the pb is that to do that I'm leaning on the engine is not obvious.
No, it's even easier, I have to press "night shot".
I would also have to put some ice in the tube of water that would be more visible.
In fact it is the encoding that reduces the brightness and quality of the video as a whole.
Good but otherwise it is still obvious the difference between with and without venturi! : Shock:

Yes reassure yourself, it's very obvious and your editing to highlight it is well done. I would have just liked to see the head of your venturi and your stitches cut straight or bevel. And if you zoom in, you can not have your head in the engine. : Cheesy:

Do not worry I'm just going to redo the little bit of video that's going well and I'm going to put it in the old one : Cheesy:
Wait, I'm Pitmix : Cheesy: and in pitmix there is MIX 8)

Ah bravo, nice responsiveness! and there at least we can see well. Not bad forming the venturi, not bad! a super simple solution in any case and what is more, effective.
