If you have the time to make it, why not. The annular discharge holes around the entire circle will work well but I'd suggest making the holes a little bit larger diameter, even though the total area of all the little holes would be larger than the one main pipe - due to boundary layers (and possibly the entry and exit to each tiny hole being sharper) The best part about your new design is that you could use an 'insert' as the venturi section, and then experiment with new designs that could slide into place with different venturi diameters. In fact you've more or less created the '45DCOE weber' of lpg amos rings! If you go ahead and make that one, I _really_ want to hear more, it's a great idea! -- John McKenzie tosspam(a)aol.com abuse(a)yahoo.com abuse(a)hotmail.com abuse(a)earthlink.com abuse(a)aol.com vice.president(a)whitehouse.gov president(a)whitehouse.gov sweep.day(a)accc.gov.au uce(a)ftc.gov admin(a)loopback abuse(a)iprimus.com.au $LOGIN(a)localhost world's #1 sardine whisperer root(a)mailloop.com $USER@$HOST $LOGNAME(a)localhost -h1024(a)localhost abuse(a)msn.com abuse(a)federalpolice.gov.au fraudinfo(a)psinet.com abuse(a)asio.gov.au $USER(a)localhost abuse(a)sprint.com abuse(a)fbi.gov abuse(a)cia.gov

I will first test the one I am currently working on (like the model I made of cardboard). If it perform good I'll stop there, if not I will fabricate this new one. And I will report here, you were all very helpfull. -- ___ ____ /__/ / \ ** Registrovani korisnik Linuksa #291606 ** / / \/ /\ \ ** Registered Linux user #291606 ** /__/\____/--\__\ ** http://counter.li.org/ ** |
