Mootada biyaha waa qalbiga nidaamka waraabinta. Xulashada sax: dheellitir u dhexeeya qiimaha, awoodda, iyo ilaha tamarta (gaaska, korontada, qorraxda).The pump is the heart of any irrigation system. The right choice balances cost, capacity, and energy source (diesel, electricity, solar).المضخة قلب نظام الري.Pampu ni moyo wa mfumo.

Awooda baahi: HP = (Q × H) / 76 / efficiency, halka Q = m³/s, H = mitir total head (taagga + cadaadiska). Tusaale: 5 L/s = 0.005 m³/s, head 30 m, efficiency 60% → 3.3 HP. Ku dar 25% safety margin.Power need: HP = (Q × H) / 76 / efficiency, where Q in m³/s and H is total head (lift + pressure). Example: 5 L/s × 30 m head ÷ 60% efficiency → 3.3 HP. Add 25% safety margin.HP = Q × H ÷ 76 ÷ كفاءة.HP = Q × H ÷ 76 ÷ ufanisi.

Beerta 1 hektar oo drip ah waxay rabtaa 1–2 kW panels. ROI: 3–5 sano oo lacagta lagu kasbado, ka dib bilaash 10 sano. NGO-yada (FAO, USAID) waxay siiyaan subsidies 50% solar pumps Soomaaliya.A 1 ha drip system needs 1–2 kW of panels. Payback 3–5 years, then free water for the next decade. FAO and USAID often subsidise 50% of solar pump kits in Somalia.1–2 كيلوواط لكل هكتار.kW 1–2 kwa hektari.
