To all, Now that the water is clearing up on this one, let me muddy up again. I agree that the drain does not need to be included in the hydraulic calculations, however what happens to this configuration for a water delivery calculation. I would think the tie-in would need to be included because of the (minimal)added volume, but more so because the effect a tie-in drain may have on the side of the system that is opposite your calculated sprinklers and how it affects the compression of the air in other areas of the system. I think this would definitely affect water delivery in a low pressure system.
I have done water delivery calculations, but I haven't attempted anything other than side feed trees. In the calculations I have done, I have found it amazing what some small things can affect a calculation where seconds are precious. At this point, I don't not believe that the water delivery software would accept this. And when I have some free time, I'll attempt it. Does anybody have any thoughts on this one? I don't see anything in NFPA '13 '02 other than the delivery requirements. Can of worms anyone?
