Points well taken Cecil (as in thank you sir may I have another). Oddly enough, I had you and your kids in mind when I figured the 60 watt bulb versus a gallon of milk on the moon. If I was an excellent instructor, I would teach hand calcs first like you do, but also offer extra credit for calcing the same set-up on the moon, given only that water weighs 12 lbs/ft^3 there. 'moonshots of milk' relates The First Law of Thermodynamics with what is called "the most far reaching generalization of the human mind"- The Law of Gravitation, so moonshots applies to sprinkler work only as far as heat and pressure do. The 2 or 3 out of 10 that get the extra credit are the ones who will some day hear that click or whistle or gong or whatever it is that turns a heart in to a big sprinkler head. I gotta believe the finer wealth you seek is to increase that number- then you can coach the annual Acadamy Techs vs U of Maryland FPE game, and win! I can not tell you how the numbers I wrote below have any bearing on you designing a system, but then, that is not why I posted them- that reason is more along the lines of 'hey everybody, look what the TECH drug in'! Thanks for the 'curious energy' part, I think. It is both a blessing and a curse: just before she was the X, the X told me "write a book, I'll read it, BUT SHUT UP ALREADY". Truly sincerely, Brad ------------- Brad, I am not sure about what is really going on here. Your messages make little
sense to me as they apply to the industry and what we do. Possibilities are endless in our world. Let's stick to the realities and rules rather than such things as "moonshots of milk" and "possible" number of iterations for a certain number of sprinkler heads to have various demands. If the numbers you wrote below have any bearing on my designing a system, please tell me how. I would love to find a way to harness that curious energy of yours (I'd be friggin' rich), but I need to know how junk applies.
