Hello

I would like to know if someone could help me calculate the exact length of tube that should be installed for a ventilation rate of 1200m ^ 3 / h.

If you could give me the formulas it would be great.

I tried by the number of reynolds prandlt and nusselt but what I find is really low so I tell myself that I forgot a step.

Thank you in advance.

Hi nico
Dsl I can't help you, but I just wanted to say hello

Hi Asyntaf

I have personally used software developed by the University of SIEGEN (Germany)

Its name: GAEA V1.4

It is hyper (too) complete with various and varied calculations, but you do not have to use all the options.

Optional English or German

It can be used free of charge for testing by downloading it from their site:

WWW: http://nesa1.uni-siegen.de/
E-mail: heidt@physik.uni-siegen.de

Regarding your air flow, I'm a little confused. Either you have a VERY large house, or you got stuck on your nominal flow ...

I for my part chose 4 lines D100 mm length 50m which for a flow of 300 m3 / h are close to 90% of output

For an identical section 4 lines of D100 have a yield much higher than 1 line of D200. but at work level, it's practically 4 times harder ...

A+

Asintaf, knowing your English (same level as mine) I feel that you're going to shit, otherwise I found that but it is certainly less complete than the JLS site.

thank you for your help JLS but in fact I had already looked with the GAEA software and it does not bring me what I want because it is you to enter your data and you to see what is best so here ...
Otherwise for the flow c the good c just that c not for a house c a large building.
I have already made calculations but they seem very inconsistent compared to the commercial method suddenly I doubt ...

And for your installation I can tell you right away you have too many pipes c useless because with 2 times less pipes I am sure you were doing as well.
I saw a technique for sizing (of course approximate) c for 7.5m3 of the building it makes 1m of pipes and it seems completely coherent to me.
yours a small site http://monpuit.est-ici.org/
He measured with temp probes what it gave and it was very interesting.
But I would like to know the real calculation method if a heat transfer specialist goes through it;)

For you live your site you already showed it to me and unfortunately there is nothing more than what I already know if you find one with formulas and not the approximation I want.
Finally go I will be nice to you I say thank you anyway ^^.
