Alfaluva,
You're on the right track with the distance it travels from the point of entry to exit and phase change is one contributor to the uneven end result.
Katman,
We have no problems with questions or anothers point of view, the only thing we have problems with is "closed minds" so as long as you have an open mind you're welcome here.
Your comments are correct (to a degree) and I suspect that's why they aimed it all to the center because they couldn't think of a way to get an even distribution but that's a poor way to design a product.
To be hoenest it's not easy to design a plate that will not result in uneven distribution but I've now got a couple of designs that I'll prototype and one will be put into production in the near future.
My main point is that if a job is worth doing it's worth doing right and as usual Zex haven't got it 100% right but it's probably better than most of the others on the market (thanks to the turbulence created by all the plumes being fired at the center), so it will probably sell well.
By the way I have the same principles (contrary to popular opinion) that I don't care who makes a product or where it's from and that's what annoys me when people say I'm anti-American, because it's nothing to do with them being made in America, it wouldn't matter to me where they were made (and in actual fact most parts are made for the American companies by other Third world companies anyway), it's JUST the poor designs and it just happens that 99% of nitrous companies are based in America.
Anyway the question still stands and for the record it's just for educational purposes. Here's a clue to one of the causes, the same problem applies to the standard spray bar that we recently assessed and the original US style distribution blocks.
Regards
