Hi, I have a couple of questions about properly setting up my zones advanced settings on my new gen. 3 Rachio:
I live in italy, so I’m using the metric system. I have a single long dripline that is watering my hedge (shrubs). The nozzles are each one 33cm apart (12,9") and each plant is, on avg, placed 75-100cm (29,5-39,3") from the others, so on avg each plant has 2 nozzles in its proximity. The nozzles have a flow rate of 2 liters per hour (0,53gph). For the “Nozzle cm per hour” I have calculated that for each sq meter (linear meter?) I have approximately 3 nozzles emitting 2cm (1 cube meter is 1000liters) per hour each one, so this adds up to a value of 6cm per hour (2,36" per hour per sq m). Is the calculation correct by assuming a value per square meter (even on a single linear dripline?) or should I consider a value per square ft, even if I set up the controller by using the metric system?
It seems a bit too high, maybe I did something wrong in the math. Currently I’m using half the value because, in theory, no plant has all 3 nozzles very near.
My second doubt is on setting the right area of my lawn. It has been divided by my gardener in 2 physical sprinkler zones, one is covering the NE part and the other the SW part, even if it’s still a single piece of grassland. So I have 2 different zones on Rachio, but the solution is not that bad because the second part is mostly in the shade and stays way more wet, while the first one is always in the sun, so I can set that accordingly. Let’s say that on a logical level the first zone covers 70% of the lawn while the second one the 30%. The problem is that, obviously, the sprinklers are overlapping in some points between the 2 areas, so for an optimal configuration of both zones sq meters should I consider the logical division of the lawn (so that the sum is exactly 100% of the lawn area) or the exact zone value with the overlapping (so the sum will be > 100%)?
As for the first question, I’ve set the lawn nozzle cm per hour with the value found in the data specs of the product, which is in mm/h (per sq meter I think), is this ok or should I consider it per sq ft?
Sorry for the long post.
