Te whakaroa maroke
Rere hau L=[(10-12)d] L/min
Ko te roa o te pūwero hiko e pupū ake ana i te waea, ko te roanga maroke te roa. Ko te tātai whānui he 10-15 ngā wā o te whānui o te waea L = (10-15) d. Mēnā he nui te paerewa, he paku nui ake. He iti te whakatakotoranga, he paku iti ake.
Te totoro maroke mō te roa rawa: Ina roa rawa te roa o te waea whakarewa, ka nui ake te ātete o te wera o te waea whakarewa, ka tere ake te tere rewa o te waea whakarewa, ka ngāwari ai te hanumi o te waea whakarewa ki ngā wāhanga, ka pakaru, ka rewa te hohonu, ka kore e pumau te mura o te pewa. I taua wā anō, kāore i te pai te pānga tiaki hau.
He poto rawa te totoro maroke: he ngāwari te tahu i te pūwero hiko. I taua wā anō, he ngāwari te whakapiri i te waea ki te pūwero hiko ina wera. Ka āraihia te pūwero e ngā tauhiuhi, ā, ka rewa hohonu.

Te rere o te hau
Rere hau L=[(10-12)d] L/min
Nui rawa: ka puta he aueue, ka uru mai te hau me ngā pūwero, inā koa mō ngā rauemi e pāngia ana e te hau (pērā i ngā koranu konumohe, ngā koranu konupora, me ētahi atu, he pūwero ā-roto te nuinga)
He iti rawa: he ngoikore te tiaki hau (ka taea e koe te tirotiro i ngā tikanga here, ko te tikanga kāore he hau tiaki, ā, he ngāwari te puta o ngā kōhao rite ki te honikoma).
Kāore te tere o te hau e pāngia ina ≤2m/s.
Me mahi ngā mahi ina ≥2m/s te tere o te hau.
① Whakanuia te tere o te rere o te hau.
② Whakamahia ngā mahi ārai hau.
Kia mōhio: Ina puta he turuturu hau, ka puta he pū kōhao hau ki te mea whakarewa. Me whakahaere te pūwāhi turuturu hau, ā, kāore e taea te tāpiri mā te whakanui ake i te tere rere. Kāore he huarahi hei whakatika i ngā pū kōhao hau me te kore e tangohia. Ka nui haere noa iho te maha o ngā mea whakarewa.
Te kaha o te pewa
He rerekē ngā kaha pewa e tīpakohia ana ina rerekē ngā matotoru pereti, ngā tūranga rerekē, ngā whakatakotoranga rerekē, me ngā waea whakarewa rerekē.
Nui rawa: he pewa mārō, he pīataata nui.
He iti rawa: he pewa ngohengohe, he pīataata iti.
Te kaha pēhanga
Kikī rawa: Kua hē te āhua o te waea whakarewa, kāore i te pumau te whāngai waea, ā, he ngāwari ki te whakararu i te waea me te whakanui ake i te tauhiuhi.
Wetekina rawatia: Ka paheke te waea whakarewa, ka puhoi te tukunga o te waea, kāore e pumau te whakarewa, ā, ka tauhiuhi anō hoki.
Iahiko, ngaohiko
Te tātai whaimana mō te whanaungatanga i waenga i te iahiko me te ngaohiko o te whakarewanga tiaki-hau: U=14+0.05I±2
Me whiriwhiri tika te ia whakarewa i runga i te matotoru o te rauemi turanga, te āhua o te hononga me te whānui o te waea. I te wā whakawhiti ara iahiko poto, ngana ki te whiriwhiri i te ia iti me te whakarite kia uru, nā te mea ki te nui rawa te ia, ka ngāwari te huri i te puna wairewa, ehara i te mea ka nui noa te pupuhi, engari he tino ngoikore hoki te whakakoi.
Me hanga te ngaohiko whakarewa kia pai te taunga ki te iahiko. Mēnā he tiketike rawa, he iti rawa rānei te ngaohiko whakarewa, ka pā te wai. Me piki te ngaohiko whakarewa i te pikinga o te iahiko whakarewa, ā, me heke i te hekenga o te iahiko whakarewa. Ko te ngaohiko whakarewa tino pai i te nuinga o te wā kei waenga i te 1-2V, nō reira me āta whakatikatika te ngaohiko whakarewa.
He nui rawa te ia: he poto te roa o te pewa, he nui te pīataata, he rite te ahua o te ringa o runga ki te ringa o runga, he nui rawa te teitei e toe ana, ā, kāore i te pai te hono o ngā taha e rua.
He teitei rawa te ngaohiko: he roa te pewa, he nui ake te pīataata, he koretake te ia, he iti rawa te teitei e toe ana, he whānui te whakarewanga, ā, he ngāwari te tahu i te pewa.
Ngā pānga o te tere whakarewa tere ki te whakarewa
He pānga nui tō te tere o te whakarewa ki te kounga o roto me te āhua o te whakarewa. Ina pumau te ngaohiko o te iahiko:
He tere rawa te tere o te whakarewa: ka whakaitihia te hohonutanga o te rewa, te whānui o te rewa, me te teitei o te toenga, ka hanga he poroporo whakarewa pūkohu, he pūkohu rānei, ā, ka ngau ngā matimati i te kikokiko. Ina tere rawa te tere o te whakarewa, ka pakaru te pānga tiaki hau, ā, ka ngāwari te puta o ngā pūwero.
I taua wā anō, ka tere ake te tere whakamatao o te whakarewa whakarewa, ā, ka whakaitihia te ngāwari me te pakari o te whakarewa whakarewa. Ka puta hoki he taha ki waenganui o te whakarewa, ka hua ake he whakahāngaitanga ngoikore.
He puhoi rawa te tere o te whakarewa: ka nui haere te puna rewa, ka whānui haere te porotaka whakarewa, ā, ka puea ake ngā matimati whakarewa. Ka ngāwari te tuku i te hau i roto i te puna rewa nā te puhoi o te tere whakarewa. He matotoru, he wera rānei te hanganga whakarewa o te whakarewa nā te wera nui.
I te wā e whiriwhiri ana i ngā tawhā whakarewa, me whai i ēnei tikanga: he ātaahua te āhua o te whakarewa, ā, kāore he hapa pērā i te wera, te tapahi raro, te pūwero, te kapiti, me ētahi atu. Ka whakahaerehia te hohonutanga rewa i roto i te awhe e tika ana. He pumau te tukanga whakarewa, ā, he iti te tauhiuhi. He haruru te tangi i te wā e whakarewa ana. I taua wā anō, me tutuki te hua teitei rawa atu.
