Te Tikanga Mahi a te Tūpine Francis
Kei roto i te tāpine he anga porowhita o waho, ā, whai muri ko tētahi huinga mata pūmau e kiia nei ko ngā vane tū. Muri iho ko tētahi kohinga mata neke e kiia nei ko ngā vane ārahi, kātahi ko tētahi puranga mata kei waenganui e kiia nei ko te runner, ā, i te mutunga, he paipa whakaputa e kiia nei ko te duct draft tube.
Ka tomo te rere ki te tāpine Francis mā te anga porowhita. Mā te whakaiti i te horahanga whakawhiti o te anga ka whakarite kia tomo te rere ki te wāhanga pokapū o te tāpine me te tere ōrite puta noa i te taha.
Kātahi ka rere te wai mā roto i ngā huinga mata e rua i mua i te urunga ki te kaikawe, arā, ko ngā whana pupuri o waho me ngā whana ārahi o roto. He mea pumau ngā whana pupuri, ā, ka āwhina i te arahi i te wai ki te wāhanga kaikawe. Ka āwhina hoki rātou ki te whakaiti i te awhiowhio i te rere tomo.
He mahi nui ake tā ngā vane ārahi e tū ana i waenganui i ngā vane noho me te kaikawe. Ka whakahaerehia e rātou te tere rere i runga i te hiahia hiko. Engari ka rerekē te hiahia hiko i roto i te wā. Ka whakahaere ngā vane ārahi i te tere rere o te wai, ā, ka whakarite kia rite te whakaputanga hiko ki te hiahia. Hei tāpiri, ka whakahaere ngā vane ārahi i te koki rere e anga ana ki ngā mata o te kaikawe. Ka ngana rātou ki te whakarite kia noho te koki rere tomo ki te koki whakaeke pai rawa atu hei whakamahi i te mana wai mōrahi.
