FYI - for those looking to do conversions, 1 cubic foot holds 7.5 gallons. Another useful fact I learned in my irrigation engineering course about 32 years ago is that you lose 1 PSI for every 2.31 feet you go uphill with an irrigation line (or gain going downhill). Not that this second factoid pertains to this thread at all, I just like to recall some things which I learned in college that have turned out to be helpful information. On the other hand, learning to do calculus with manual calculations has never done me one single bit of good! lol
