Well for garden irrigation

How large is the diameter of the [geschlagenem Brunnen]? You already lose almost 1 bar of pressure before you reach the surface. 2.8 bar at the sprinkler is required at minimum.

I believe the well builder mentioned 1 3/4 inch as the diameter. I am now assuming 0.7 bar pressure loss due to piping, and 0.7 bar due to height difference. With the Tipp pump, I would then have 3 bar at the sprinkler, with the Gardena pump around 3.5 bar.

I have now also found the influence of the nozzle and pressure on flow rate and range for gear-driven sprinklers at Hunter. I will make 2 plans, 1 with gear-driven sprinklers, 1 with rotators. I will then present both.

What do you use for e.g. tree irrigation?

How do you know how many bars you have at the sprinkler? Have you already taken into account pipe lengths, branches, bends, etc.? You probably meant about [Bar] at the beginning of the pipe ;)

I have already estimated this with about 0.7 bar line loss, + 0.7 bar loss due to 7 meters of height difference. So in total 1.5 bar losses. If the pump produces 5 bar, there would be 3.5 directly at the sprinkler. It all stands and falls with the estimated 0.7 bar. When I do the rough planning, I will determine the losses more precisely.

As mentioned, once a sketch with distance specifications is available, it can be better estimated.

So, first try with PGJ gear-driven rotors from Hunter. Planning with rotators I will do separately.
It would be:
-6 PGJ with 3.0 nozzle (at 3.5 bar: 13 l/min and 9.4 m throw distance)
-1 PGJ with 5.0 nozzle (at 3.5 bar: 20 l/min and 11 m throw distance)
-4 PGJ with 0.75 nozzle (at 3.5 bar: 3.2 l/min and 5 m throw distance)

-The 4 PGJ with 0.75 nozzle would form one circle (13 l/min => 800 l/h)
-The remaining 7 PGJ (100 l/min => 6000 l/h) would be divided into 2 circles (if the well allows it)

=> With that I could use a 4-valve box (3 circles with sprinklers) and the 4th circle would be for drip irrigation. But I have several flower beds (dark green). Is that feasible with a huge drip hose?

Numbers in the circles stand for the number of overlaps.

What I haven’t considered at all so far is the precipitation rate. We have a clay soil with about 20 cm of humus on top.
Are there any recommendations? I don’t want everything to soak because the water can’t infiltrate fast enough (areas with 4 overlaps?)
