Hydraulic Remote Area

[spkreng]

say I have a light hazard area .1 over 1500 (tree), I measure from the wall along the last branch line 46.5' and it ends up 9'from head A and 5' to head B (which is closer to the main) so I have to pick up head B, right, thus making the length along the line 57.5' (B and C being 12' apart) the next line is the same (lines 14' apart) now I have a remote area of 1610 sq ft, I can now reduce the density to .093 correct? my question is now the remote area corrosponds to a 2300 sq ft area by length, do I revise the remote area to this (upward departure) at a .065 density picking up another line or leave well enough alone? as it could go on forever!

If I understand your question correctly.

If the area of calculation ends up being 1,610 sq. ft. you may reduce the density to 0.097 (I think you misread the graph coming up with 0.093) but in practice this is rarely done. The difference between the two is so small it amounts to nothing and if your calculations are that close you should consider of upping the size of something.

As to the second part of the question "my question is now the remote area corresponds to a 2300 sq ft area by length, do I revise the remote area to this..: the answer is no, an adjustment can not be made with this.
