He aha te rerekētanga i waenga i te Kore Whakahoki me te Taki Taki

I a koe e mahi ana me ngā pūnaha paipa, ka rongo pea koe i ngā mea e ruatakirere kore-hoki (NRV)metakirere tirotiroe whakamahia ana. I te tuatahi, tera pea he rite ki ngā takirere rerekē e rua. Engari he rite tonu rānei? He rerekētanga rānei hei mōhio? Me wehewehea kia māmā noa iho.

He aha te Takirere Kore-Hoki (NRV)?

Ko te takirere kore-hoki he momo takirere e tuku ana i te wai—ahakoa he wai, he hau rānei—kia rere i te taha kotahi anake. Kia mutu te rere, kia ngana rānei ki te hoki whakamuri, ka kati aunoa te takirere. Mā tēnei mahi ka ārai i te rere whakamuri, ka kino pea ngā taputapu, ka poke rānei i ngā mea ma.

E whakamahia whānuitia ana ngā NRV i roto i:Ngā pūnaha tuku wai hei ārai i te poke.Ngā papu hei aukati i te rere whakamuri ina whakawetohia te papu.Ngā paipa ahumahi e tino hira ana te pupuri i te rere kotahi te ara.

He māmā noa iho te kōrero matua: mā te NRV ka whakarite kia haere whakamua te wai, ā, kāore e hoki whakamuri.

He aha te Takirere

He rite tonu te kaupapa o te takirere tirotiro. Ka aukati hoki i te rere whakamuri, ā, ka whakarite kia kotahi te huarahi e neke ai te wai. E kitea ana ngā takirere tirotiro i roto i te nuinga o ngā ahumahi, mai i te maimoatanga wai ki te hinu me te hau.

He maha ngā momo takirere tirotiro, pērā i:Ngā takirere tirotiro hurihuri (me te kōpae hono ka hurihuri tuwhera, ka kati rānei).Hiki ake ngā takirere tirotiro (ka hiki ake, ka heke iho rānei te kōpae i te rere).Ngā takirere tirotiro pōro (he pōro te mahi hei tikanga kati).Ngā takirere tirotiro angiangi (hoahoa kiato mō ngā wāhi kuiti).

Nā, he aha te rerekētanga?

Anei te wāhi e tino whakamere ai ngā mea. Ko te pono: he rite tonu te takirere kore-hoki me te takirere tirotiro. Ko te rerekētanga matua kei roto i te kupu.

• Ko te takirere kore-hoki (NRV) te kupu whānui, e whakamahia whānuitia ana i te reo Pākehā o Peretānia me ngā ahumahi e pā ana ki te wai.

• Ko te kupu takirere tirotiro te kupu e whakamahia whānuitia ana, inā koa i te reo Pākehā o Amerika me ngā horopaki ahumahi, ā-mīhini rānei.

Nō reira, ina kīia e te tangata ko te NRV, kei te kōrero rātou mō te taputapu kotahi e kiia nei e tētahi atu he takirere tirotiro. He kotahi te kaupapa o ngā mea e rua: te ārai i te rere whakamuri.
