WHAKATAKI TĪ
Ko te Paipa Tī he momo hononga paipa he āhua-T, e rua ngā putanga, i te 90° ki te hononga ki te raina matua. He wahi paipa poto me te putanga taha. Ka whakamahia te Paipa Tī hei hono i ngā paipa me te paipa kei te koki matau ki te raina. He whānuitia te whakamahinga o ngā Paipa Tī hei hononga paipa. He maha ngā rauemi e hangaia ana, ā, e wātea ana i ngā rahi me ngā whakaotinga rerekē. He whānuitia te whakamahinga o ngā paipa tī i roto i ngā whatunga paipa hei kawe i ngā ranunga wai e rua-wāhanga.
Momo Tī
- He tī paipa tika anō hoki, he rite te rahi o ngā pūaha.
- Kotahi te whakatuwheratanga o ngā tī paipa whakaiti he rerekē te rahi, me ngā whakatuwheratanga e rua he rite te rahi.
