Ina whakamahia te pūwero hei mārama i te whanonga o te totoka me te wai i raro i te ahotea kutikuti, ka tukuna e te ahua 2 he whakaaturanga kanohi o te whārite 3. Ko te matotoru, e whakaatuhia ana i roto i ngā centipoises, he mahi nui tana i roto i te raruraru nekehanga wai. He maha ngā wā ka whakaatuhia hei matotoru kinematic, e tohuhia ana e te kupu volt, ko te ōwehenga o te matotoru ki te mātotoru me te mugwump o te kaha. Hei tauira, ka taea e te hinu taumaha te whakanui i te matotoru kinematic tae atu ki te 900 x 10-6m2/hēkona, ko te wai ia he iti ake te uara moenga o te 1,14 x 10?m2/hēkona i te 15° nekehanga centigrade. Ka heke te matotoru kinematic o te wai i te pikinga o te pāmahana, kia tata ki te 13 ngā wā o te matotoru kinematic o te hau i te koki pāmahana rūma i te koki hāora.
Ko te taumahatanga mata he āhuatanga ā-tinana taketake e āhei ai te puta o ngā āhuatanga whakamere pērā i te whakatarewatanga o te pata wai i te pakū, te rere rānei o te rau karaka i runga i te mata o te wai. Ka puta mai tēnei āhuatanga i te hononga i waenga i te taunekeneke a te ngota i te mata o te wai ki tētahi atu wai, hau rānei e kore e taea te whakaranu. Ko te kaha taumahatanga mata mō ia waeine o te roa ine ka inehia ki te konupora/mita, ā, he iti noa iho, tata ki te 73 konupora/mita mō te wai i te pāmahana rūma. Ahakoa he iti noa te taumahatanga mata i roto i te tono waipēhi ki te whakataurite ki ētahi atu kaha, ka noho hei mea nui i roto i ngā āhuatanga he mata kore utu me te rahi rohe iti, pērā i roto i ngā tauira waipēhi.
Ko tētahi hua mārama o te taumahatanga o te mata ko te capillarity, te wāhi e whakaatu ana te ngongo iti e tuwhera ana ki te hau i te kaha taumahatanga o te mata. Ka kitea tēnei ina rumakina he ngongo karāhe ki roto i te wai, ka piki ake te taumata wai i roto i te ngongo, ka hanga he meniscus piko. E whakaatu ana tēnei āhuatanga i te taha o te piri i waenga i te wai me te karāhe ki runga i te ōritetanga o roto o te wai. He mea nui te mārama ki te matotoru me te taumahatanga o te mata i roto i te wai mō ngā tono pūtaiao me ngā mahi, e whakamārama ana i te whanonga uaua o te wai i raro i ngā āhuatanga rerekē.
te māramatangangā purongo pakihi:
He mahi nui tā ngā purongo pakihi hei pupuri i te tangata kia mōhio ki ngā whanaketanga hou o te ao pakihi. Ahakoa he whakakotahitanga, he hoko, he ia o te mākete, he pūrongo pūtea rānei, mā te whai i ngā purongo pakihi ka taea te whakarato i te urunga whai hua ki te kaipupuri moni, ki te kaipakihi, me te tohunga ngaio. Mā te tātari i ngā purongo pakihi, ka taea e te tangata te whakatau pai mō te waitohu, te tumanako ki ngā huringa mākete, me te tautuhi i ngā whai wāhitanga pea mō te tipu. Hei tāpiri, ko te mārama ki te pānga o te āhuatanga ōhanga, te ture ahumahi, me ngā huihuinga o te ao ki te pakihi he mea nui hei whakatere i te whenua mana matatika o te ao pakihi. I te nuinga, ko te noho mōhio ki ngā purongo pakihi te mea nui hei noho whakamua i roto i te taiao pakihi whakataetae o ēnei rā.
