Ko ngā rerekētanga matua i waenga i ngā ngongo me ngā paipa i roto i te paerewa

Āhua rerekē

Tengongohe waha ngongo tapawhā, he waha ngongo tapawhā, he porowhita te āhua; he porowhita katoa ngā paipa;

Rerekētaratara

He pakari ngā ngongo, me ngā ngongo ngāwari i hangaia ki te parahi me te parahi; he pakari ngā paipa, ā, he ātete ki te piko;

Whakarōpūtanga rerekē

Ngā ngongo e ai kite whānui o waho me te matotoru o te pakitara; paipa e ai ki te waehere matotoru pakitara o te paipa me te diameter ingoa (Paerewa Pākehā) = rahi paipa ā-motu (Paerewa Amerikana)

He rerekē te whakamahi i te taiao

Ka whakamahia ngā ngongo ina hiahiatia he diameter ngongo iti. He onge ngā ngongo 10 inihi. Ka whakamahia ngā paipa ina hiahiatia he diameter ngongo nui. He mea noa ngā ngongo 10 inihi, mai i te hawhe inihi ki te maha putu.

Ngā whakaritenga arotahi rerekē

Ka aro te ngongo ki te tika o te diameter o waho, nā te mea he pēhanga kei roto, e whakamahia ana mō te ngongo whakamatao, te ngongo whakawhiti wera, me te ngongo poihau; ka aro te paipa ki te matotoru o te pakitara, nā te mea ko te nuinga o te paipa he kawe wai, ā, me nui te kaha pēhanga o roto e hiahiatia ana;

He rerekē te matotoru o te pakitara

Ka whakanuia te matotoru o te pakitara o te ngongo mā te 1 taumata, ā, ka whakanuia te matotoru o te pakitara mā te 1mm, 2mm rānei, ā, ka pumau te pikinga. Ka whakaatuhia te matotoru o te pakitara o te paipa mā te rārangi wā. Kāore i te tino mārama te whanaungatanga i waenga i ngā uara o ngā taumata rerekē. He mahi nui te hononga o te paipa, ā, ka taea te whakarewa. Ka taea hoki te hono mā te miro, mā te flange rānei.
