You main limitation is the blue striped header line which is 5/8". I would not put more than 5gpm through that. You can figure out how much you are using by adding up the footage. The dripperline uses .45 gpm per 100'. Therefore, 9 100' rows is using 4.05 gpm. You should be able to safely add 100', and likely get away with another 200'.
You can estimate your precipitation rates by using the charts on page 16 of our catalog. You ill need to know how far apart your rows are (row spacing) and take it from there. If you are using 15' of header with 9 rows, that would be about a 20" row spacing. It doesn't show on the chart. At 30" it would be .173"/hour. In this case you would need to calculate it using the formula on page 129 of our catalog, which comes to 3.83 hours per week with a 20" spacing. Hopefully this will get you your answers. --Previous Message-- : Good Morning, : We have your kit A for a new garden area, we : get 10 GPM from the hydrant and we have 15' : of 16mm tubing with 9 runs, 100' in length. : It seems to be wetting the soil to the end, : how much more tape can we add on to this : before it needs another zone. How long do : we need to run water to get 1" per : week? : We also are using some of this drip tape for : another section of the garden, we are using : the 12" and another drip tape by Toro : with the slits at 8"apart, the same 10 : GPM at the hydrant and then we are using a : timer and splitting into 2 sections, one : section is 100' of the 16mm tubing from : hydrant that came in the kit with (38)- 28' : runs 30" apart. The other section is : 100' of 16mm tubing with (38)- 35' runs. : How long do we need to run water to get : 1" per week. We have a filter and : pressure regulator on this section that is : rated 10-20 PSI. : Tests show we have enough organic matter in : this sandy soil. : I hope I have included all the information : you need. : Your input would be greatly appreciated. : Thank you, PJ : Tests show we have enough organic in this : sandy soil. : : |
