TB, I don't mean to come off as I don't appreciate the concepts you're trying to illuminate to me, I do get the concepts, but I am stuck at the design phase, not even into an operational mindset at this point, I did not take offense, to your comments, if only to the concept of rereading all that to try to gleam the few useful tidbits I did on that first rather long read through, I think in total it was over 400 pages of posts we're talking about re-reading here, w/ about 10% of that being anything relevant, so please do understand my resistance and its root cause.
I do fully agree Atomizer's calculation he mentioned is certainly something for people in an operational status to focus on, and Id like to take the time to thank him for setting me straight on Stoner, that book from 55 which is truly the origin of this method, as well as the two practical examples of an older working systems.
I believe PodRacer and then Stoner are good stepping stones, I certainly learned a lot from reading their available information, my main concern comes down to specifics, Stoner is the only one that I know that has a documented layout of a system, every piece, every connection, if you look at the available pieces on aerponics.com which you obviously did since that's where you got the sprayers, you can see that his system is fully layed out, except he used vinyl tubing.
It seems silly to me that my main concern at this point is whether the tap adapter coming out of the accumulator tank tapers from the 3/4" BSP into a 1/4" or 3/8" John Guest -> Swivel Branch Tee 1/4" or 3/8" x 3/4" NPTF x 1/4" or 3/8" John Guest, the NPTF goes to either a Piston Style Pressure Relief Valve, which has a port on it for a 1/4" NPTM pressure gauge, or the NPTF goes to a Dayton Pressure Relief Valve, then the end of the STB goes into another STB which has a 1/4" NPTF or M, which will have to be adapted, then a 1/4" NPTM pressure gauge.
Based on what is available above, then we go into a 1/4" or 3/8" John Guest Solenoid Valve -> Two Way Divider 1/4" or 3/8" -> 1/4" or 3/8" Swivel Branch Tee x 1/4" or 3/8" (only sizes available if only they had a 1/8" F) x 1/4" or 3/8", out of the center of the tee the 1/4" or 3/8" would be reduced or coupled (still hunting for the proper term for NPT and female to female connectors)
So sorry if I've seemed frustrated, the logistics on this are not nice.
