Te tikanga mō te wehewehe mēnā ka tahuna te ngongo whakamahana hiko ki te wai, ki te maroke rānei:
1. Ngā hanganga rerekē
Ko ngā ngongo whakamahana hiko wai e whakamahia whānuitia ana ko ngā ngongo whakamahana hiko kotahi te pane me ngā miro, ngā ngongo whakamahana hiko āhua-U, āhua-motuhake rānei me ngā here, me ngā ngongo whakamahana hiko he mea whakarara.
Ko ngā ngongo whakamahana hiko tahu maroke e kitea whānuitia ana ko ngā ngongo whakamahana hiko tokotoko kotahi te pane, ngā ngongo whakamahana hiko āhua-U, āhua-motuhake rānei, kāore he here, ngā ngongo whakamahana hiko whai tara, me ētahi ngongo whakamahana hiko he flange.
2. Ngā rerekētanga o te hoahoa mana
Ka whakatauhia te hoahoa mana e te ngongo whakamahana hiko wai e ai ki te reo whakamahana. Ko te mana o te rohe whakamahana he 3KW ia mita o te ngongo whakamahana hiko. Ka whakatauhia te mana o te ngongo whakamahana hiko maroke e te rere o te hau e whakamahanahia ana. Ko ngā ngongo whakamahana hiko maroke e whakamahanahia ana i ngā Wāhi Kuiti he mea hanga mō te mana o te 1Kw ia mita.
3. Ngā kōwhiringa rauemi rerekē
Ko te paipa whakamahana hiko wai e whakamahi ana i te kowiri tira 304 hei whakamahana i te wai puna, ā, ko te wai inu e whakamahi ana i te kowiri tira 316. Mō te wai awa paru, mō te wai rānei he nui ake ngā poke, ka taea e koe te whakamahi i te ngongo whakamahana hiko paninga anti-tauine. Ko te pāmahana mahi o te paipa wera he 100-300 nekehanga, ā, ko te kowiri tira 304 te mea e taunakihia ana.
