Ok great, I see that now. Not a setting I've ever changed before. Thank you!


Another question: I see the dripline now calculates in the flow totals (so awesome!!!). But the total it kicked out is not what my manual calculations come to. What formula did you use?
I have 2940' of Netafim TLCV-04-18. Flow Totals calculates that equates to 12.4 gpm.

According to the Netafim dripline calculations shown at the back of their catalog:

Number of emitters per zone = (total dripline lf x 12)/emitter spacing inches
# emitters = (2940 x 12)/18 = 1960 emitters

Flow per zone = (# emitters x emitter flow rate gph)/60
Flow per zone = (1960 x .4)/60 = 13.06 gpm

In this example, it's so small a difference it doesn't really matter. But a larger project could be problematic. Just looking for clarification.

Thanks

I added the TLCV-04-18 to a project as Area for Dripline, and applied it to an area of 4,409 sq.ft.
The schedule shows 2,940 l.f. of dripline, and the Flow Total shows 13.1 gpm for Area for Dripline.

It's not the area dripline item, it's the linear dripline item. I'm sorry, perhaps there's something I'm missing. Attached my file (ignore the design quality, it was fast for budget purposes only).

Ah sorry, I don't know why I saw that and assumed Area.
Yes, you're right, 2940 (x 12) / 18 = 1960 emitters, @ 0.4gph = 784gph = 13.06gpm.
However the system is calculating it for each individual segment.
So for instance I found one that is 2.34', so that's 28.08" / 18 = 1.56 emitters, which it is then rounding DOWN to 1 emitter.
It absolutely should be rounding it, or always rounding up.
I've flagged it for investigation, we'll get that corrected with a future update.

So glad I'm not going insane... today! Would have never thought about the rounding.
Thanks as always!

HI,

I have a probelm detecting "dry islands" when placing area for dipline .
1. checked if polyline is closed - and it is
2. Place area for dipline
3. M (for multiple)
4. Select outer boundary- selected
5. F/X immidiatelly places dripline hatch all over inside the "outer boundary" , not even trying to ask me for the inner boundary?

Am I doing something wrong or should I just restart FX program?

Solved...
Outer boundary was a closed polyline but with a small extra polyline hanging out from the "inner" area...
Always double check for some extra vertex spoiling the "plolyline flow"

Cheers
