Answer

Die hommeltig kan help om die oesopbrengs op 'n besproeiingsland te verbeter deur:

  • 'n multispektrale kamera op die hommeltig te monteer, wat data verskaf oor die vegetatietoestand.
  • Die kamera kan vog variansies in die grond waarnemen en 'n geografiese kaart verskaf.
  • Dit kan ook probleme identifiseer, soos 'n gebrek aan water of bande wat pap is, wat aksies kan stimuleer om die opbrengs te verhoog.

Step 3

6.2.2 Noem die sisteem wat op die hommeltig gemonteer word om presiese ligging te bepaal.

Answer

Outomatisering van 'n besproeiingsstelsel help om die volgende te verwesenlik:

  • Om water te bespaar.
  • Voorkom oorbesproeiing.
  • Voorkom ondersproeiing.
  • Om geld te spaar.
  • Optimale arbeid en bediening.
  • Afstand beheer en kontrole.

Step 7

6. Beskryf die werking van 'n plaashuis septiese stelsel vanaf die punt afvankal in die toilet gespeel word.

Answer

Die werking van 'n plaashuis septiese stelsel begin wanneer:

  • Afval bereik die septiese tenk deur die inlaatpyp.
  • Swartwater vloei in die tenk.
  • Die ligter afval sink tot onder in die tenk, terwyl die soliede afval wat gesak het word deur bakterië afgebroke en vorm sluk.
  • Die oorvloei van die septiese tenk word na die absorpsiemings gebied vrygelate deur uitlaatpyp.

Step 8

7 Noem TWEE soortmateriaal wat algemeen gebruik word vir die vervaardiging van reinwater geute en afvoerpype by plaasgeboue.
