Tātari Y
✧ Whakaahuatanga
He taputapu tātari tino nui te tātari Y i roto i te pūnaha paipa o ngā pāpāho kawe. Ko te tātari momo-Y te tikanga ka tāutahia ki te pito tomo o te takirere whakaiti pēhanga, te takirere whakaiti pēhanga, te takirere taumata pumau, me ētahi atu taputapu hei tango i ngā poke i roto i ngā pāpāho hei tiaki i te whakamahinga noa o ngā takirere me ngā taputapu. Ko ngā āhuatanga o te tātari momo-Y he hanganga matatau, he ātete iti, he pupuhi watea me ētahi atu. Ko te pāpāho tātari momo-Y ka taea te wai, te hinu, te hau. Ko te nuinga o te whatunga wai he 18 ki te 30 mata, ko te whatunga hau he 10 ki te 100 mata, ā, ko te whatunga hinu he 100 ki te 480 mata. Ko te nuinga o te tātari kete he mea hanga mai i te pūwero, te paipa matua, te kikorangi tātari, te flange, te taupoki flange me te whakapiri. Ina uru te wai ki te kikorangi tātari mā te paipa matua, ka āraia ngā matūriki poke totoka ki te kikorangi tātari, ā, ka tukuna te wai ma mā te kikorangi tātari me te putanga tātari.
He āhua-Y te tātari momo-Y, ko tētahi pito hei whakaputa wai me ētahi atu wai mā roto, ko tētahi pito hei whakarewa i ngā para, i ngā poke, i ngā mea poke. Ko te tikanga ka tāutahia ki te takirere whakaiti pēhanga, ki te takirere whakaiti pēhanga, ki te takirere taumata pumau, ki tētahi atu pito whakaurunga taputapu rānei. Ko tana mahi he tango i ngā poke i roto i te wai, hei tiaki i te takirere me ngā taputapu kia mahi noa. Ko te mahi a te tātari kia tukatukahia e te whakaurunga wai ki roto i te tinana. Ka whakatakotoria ngā poke i roto i te wai ki runga i te tātari kowiri tira, ka puta he rerekētanga pēhanga. Aroturukihia te rerekētanga pēhanga o te whakaurunga me te putanga mā te pana rerekētanga pēhanga. Ina tae te rerekētanga pēhanga ki te uara kua whakaritea, ka tukuna e te kaiwhakahaere hiko te tohu ki te takirere whakahaere waipēhi me te motuka taraiwa hei whakaoho i ngā mahi e whai ake nei: Ka peia e te motuka te paraihe kia huri, ka horoi i te huānga tātari, i te wā e tuwhera ana te takirere whakahaere mō te tukunga paru, ka roa noa te tukanga horoi katoa mō ngā tekau hēkona, ina oti te horoi, ka kati te takirere whakahaere, ka mutu te hurihanga o te motuka, ka hoki te pūnaha ki tōna āhua tuatahi, ka tīmata ki te tomo ki te tukanga tātari e whai ake nei. I muri i te tāutanga o ngā taputapu, ka whakatikatika ngā kaimahi hangarau, ka whakatakoto i te wā tātari me te wā hurihanga horoi, ā, ka tomo te wai hei tukatuka ki te tinana mā te tomokanga wai, ā, ka tīmata te tātari ki te mahi noa.
✧ Ngā Āhuatanga o te Tātari Y
1. kaha te ārai i te parahanga, he watea te waipara; he nui te horahanga, he iti te ngaronga pēhanga; he māmā te hanganga, he iti te rahi. he māmā te taumaha.
2. He rauemi mata tātari. He mea hanga katoa ki te kowiri tira. He kaha te ātete ki te waikura. He roa te ora o te mahi.
3. te matotoru o te tātari: L0-120 mata, te matotoru reo: te mamaoa, te hau, te wai, te hinu, te whakarite rānei kia rite ki ngā hiahia o te kaiwhakamahi.
4. Ngā āhuatanga karu: te roa totoro. Ka taea te toro atu ki te 100mm i te tūranga nui. He māmā ake te tāutanga. Whakapai ake i te pai o te mahi.
