I tēnei rā ka whakamōhiotia pototia ngā āhuatanga ā-tinana o ngā kirihou

1. Manawa
Ko te urunga hau e tohuhia ana e te urunga hau me te tauwehenga urunga hau. Ko te urunga hau e pā ana ki te rōrahi (mita pūtoru) o tētahi kiriata kirihou he matotoru kei raro i te rerekētanga pēhanga o te 0.1 MPa me te horahanga o te 1 mita pūrua (i raro i ngā tikanga paerewa) i roto i ngā haora 24. Ko te tauwehenga urunga hau ko te nui o te hau e haere ana i roto i te kiriata kirihou mō ia horahanga me te matotoru mō ia wā me te rerekētanga pēhanga (i raro i ngā tikanga paerewa).
2. Te uruhanga makuku
Ko te urunga makuku e whakaatuhia ana e te nui o te tirohanga me te tauwehenga tirohanga. Ko te urunga makuku ko te papatipu (g) ​​o te mamaoa wai i uruhia e te kiriata 1 mita tapawha i roto i te 24 haora i raro i ngā āhuatanga o tētahi rerekētanga pēhanga mamaoa i ngā taha e rua o te kiriata me tētahi matotoru kiriata. Ko te tauwehenga tirohanga ko te nui o te mamaoa wai e haere ana i roto i tētahi wāhanga horahanga me te matotoru o tētahi kiriata i roto i tētahi wāhanga wā i raro i tētahi rerekētanga pēhanga wāhanga.
3. Te uruhanga wai
Ko te ine i te uruhanga wai ko te tirotiro tika i te uruhanga wai o te tauira whakamātautau i raro i te mahi a tetahi pēhanga wai mo tetahi wā.
4. Te mimiti wai
Ko te mimiti wai e pā ana ki te nui o te wai ka mimitia i muri i te rumakina o tētahi rahi o te tauira ki roto i tētahi whānuitanga wai māori i muri i tētahi wā kua whakaritea.
5. Te mātotoru me te matotorutanga whanaunga
I tētahi pāmahana kua whakaritea, ko te ōwehenga o te papatipu o te tauira ki te papatipu o te rōrahi wai kotahi ka kiia ko te kiato whanaunga. Ko te papatipu o tētahi matū mō ia rōrahi i tētahi pāmahana kua tohua ka noho hei kiato, ā, ko te waeine ko kg/m³, g/m³, g/mL rānei.
6. Taupū whakaata
Ko te mārama e tomo ana ki te mowhiti tuarua mai i te wāhanga tuatahi (haunga te pānga poutū). Ko te sine o tētahi koki pānga me te sine o te koki whakaata ka kiia ko te taupū whakaata. Ko te taupū whakaata o te reo he nui ake i te kotahi, ā, he rerekē ngā taupū whakaata o te reo kotahi mō te mārama o ngā roangaru rerekē.
7. Te tuku mārama
Ka taea te whakaatu i te mārama o ngā kirihou mā te whakawhiti mārama, te kohu rānei.
Ko te whakawhiti mārama e pā ana ki te ōrau o te rerenga mārama e whiti ana i roto i tētahi tinana mārama, āhua-mārama rānei ki tōna rerenga mārama e pā mai ana. Ka whakamahia te whakawhiti mārama hei tohu i te māramatanga o te rauemi. Ko te ine e whakamahia ana he taputapu ine whakawhiti mārama katoa, pērā i te mita whakaahua porowhita whakauru ā-whare A-4.
Ko te kohu e pā ana ki te āhua kapua, pōuriuri o roto, o te mata rānei o ngā kirihou mārama, mārama rānei, i puta mai i te marara o te mārama, e whakaatuhia ana ko te ōrau o te rerenga mārama e marara ana ki te moni me te rerenga mārama e tukuna ana.

8. Kanapa
Ko te kanapa e pā ana ki te kaha o te mata o tētahi mea ki te whakaata i te mārama, e whakaatuhia ana hei ōrau (kanapa) o te nui o te mārama e whakaatahia ana mai i te mata paerewa i te ahunga whakaata noa o te tauira.
9. pokepokea aite mimiti
Ko te whakahekenga pokepokea ai e pā ana ki te nui o te rahi o te hua e iti iho ana i te rahi o te kōhao pokepokea ai mm/mm
