How to use it
- Assume area: 10m x 10m = 100m2
- Drippers: 100m2 x 11 drippers/m2 = 1,100 drippers
- Total flow: 1,100 x 4 L/h = 4,400 L/h
- Convert to L/min: 4,400 / 60 = 73.3 L/min
Common mistakes
- ⚠️ Not considering pressure drop in long irrigation lines
- ⚠️ Using incorrect dripper spacing for soil type
- ⚠️ Not installing filter to prevent dripper clogging
Worked example
Calculate drip irrigation system for 100m2 garden with drippers at 0.3m spacing.
To {area_m2}m² need {lineas_ud} líneas of irrigation, {goteros_ud} goteros, {tuberia_m}m of pipe main and {filtro_ud} filtro of {caudal_lph} L/h.
