Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Kuchenesa munyu inzira yokugadzira nayo iyo mvura ine munyu (kazhinji mvura yegungwa) inoshandurwa kuva mvura yakachena. Nzira dzinowanzoshandiswa pakuita kuti mvura isasvibiswa mvura yegungwa ndedzokuita kuti mvura isasvibiswa nemvura uye dzokuita kuti mvura isasvibiswa nemvura. Kuchenesa mvura munyu pari zvino kunodhura kana kuchienzaniswa nedzimwe nzira dzakawanda dzokuwana mvura, uye chikamu chiduku bedzi chezvinhu zvose zvinoshandiswa nevanhu chinogutswa nokuchenesa mvura munyu. Inowanzoshanda chete mune zveupfumi pakushandisa kwakakwirira (sekushandisa kwemhuri uye kwemaindasitiri) munzvimbo dzakaoma. Zvisinei, pane kukura mukuchenesa munyu nokuda kwokushandiswa mune zvokurima, uye nzvimbo dzine vanhu vakawanda dzakadai seSingapore kana kuti California. Kushandiswa kwakapararira zvikurusa kuri muPersian Gulf.  Mubvunzo: Ndokupi kuri kuitika kukura kukuru mukubvisa munyu mumvura nokuda kwokushandisa mune zvokurima?
