Ngā Whakaaro Matua
- Ka whakamahia e ngā pūnaha waipēhi te wai pēhanga hei whakanui i te kaha, hei mahi hoki i ngā mahi taumaha me te whakahaere tika, e ai ki te Ture a Pascal.
- Ngā wāhanga matua ko:ngā papu, ngā puna wai, ngā takirere, ngā whakatere, me te wai, he mea nui ia mea mō te tuku me te whakahaere hiko whai hua.
- He nui ngā ahumahi e whakakahangia ana e ngā pūnaha waipēhi mā te tuku kaha nui, te whai hua o te pūngao, me te pono, engari me tiaki tonu kia kore ai e turuturu me te poke.
Te Mahi a te Pūnaha Waipēhi
Ngā Mātāpono Taketake o te Pūnaha Waipēhi (Ture a Pascal)
E whakahaerehia ana te pūnaha waipēhi i runga i te Ture a Pascal, he mātāpono taketake i roto i te miihini wai. E kī ana te Ture a Pascal, ina pāngia he pēhanga ki tētahi wai kua herea, ka tukuna ōrite te pēhanga ki ngā taha katoa puta noa i te wai. Mā tēnei mātāpono ka taea e ngā pūnaha waipēhi te whakanui ake i te kaha me te mahi i te hiki taumaha me te iti o te whakauru.
Hei tauira, ina whakamahia e te tangata he kaha ki tētahi piston iti, ka haere te pēhanga i puta i roto i te wai mā roto i ngā paipa me ngā ngongo ki tētahi piston nui ake. Ko te piston nui ake, he nui ake te horahanga o te mata, ka puta he kaha whakaputa nui ake. Ko te whanaungatanga i waenga i te kaha whakauru me te kaha whakaputa ka whakawhirinaki ki te ōwehenga o ngā horahanga piston. Mena he 2 henimita tapawha te horahanga o te piston whakauru, ā, he 20 henimita tapawha te horahanga o te piston whakaputa, ka tekau ngā wā ka nui ake te kaha whakaputa i te kaha whakauru, ki te whakaarohia ka whakamahia te pēhanga ōrite.
Mā te Ture a Pascal ka taea e ngā pūnaha waipēhi te whakamahi i ngā paipa me ngā ipu o ngā āhua rerekē me te kore e ngaro te pēhanga, ā, he tino ngāwari ki te urutau mō ngā tono miihini rerekē.
