🚿 Sprayline Quick Check v1.0.0
Calibration check following the IrrigationNZ Code of Practice Part E, Section 2
Save everything entered on all tabs, plus the results, to a CSV file on your computer. Load it later to fill the tool back in and recalculate.
24 containers with the same known opening (over 150 mm; 9 litre buckets work well) in two lines across a representative sprayline: Line 1 straight across a sprinkler, Line 2 half way between two sprinklers. This catches the widest and the narrowest wetted widths.
On each line, L6/R6 go half way between the lane edge (half way to the next set) and the edge of obvious wetting; L5/R5 the same distance inside the lane edge; L1–L4 evenly back to the sprayline. If the wetted width is no more than the lane width there is no overlap: leave out L6/R6 and spread five buckets each side. Set Out Collectors fills in suggested distances.
What is calculated
- Applied depth after adding the overlap buckets, and the depth for your normal event
- Distribution uniformity and the excess water use factor
- Application intensity and flow worked out from the buckets
- The run time to apply your target depth to 7/8 of the area
