Whakaahuatanga Hua
He porowhita te porowhita o te kara wiri noa, he poka wai kei waenganui, he nui ake te matotoru o te pakitara, he iti ake te pūwero, ā, ko te taumaha o ia wae roa he nui ake i te rahi o te paipa wiri tata ki te 4-5 ngā wā. Ko te nuinga o ngā kara wiri he miro e tukatukahia ana ki te tinana paipa, engari ko ētahi o rātou e whakamahi ana i te hononga whakakapi.
He momo taputapu keri hinu te kara wiri porowhita. Ka taea e tēnei momo kara wiri te ārai i te pupuri i ngā taputapu i te pēhanga rerekē i te wā keri. Mā ngā awaawa porowhita ka taea te rere noa o te paru huri noa i te kara wiri hei whakamahi i te pēhanga taurite hei ārai i te hanganga o te aukati kia pai ai te ārai i te pēhanga rerekē. Ka taea te tapahi i te wāhi e pā ana ki te pakitara o te puna kia pai ai te whakaiti i te tūponotanga o te hanga aukati pēhanga rerekē. Mā ngā awaawa porowhita ka taea te rere noa o te paru huri noa i te kara wiri hei whakamahi i te pēhanga taurite hei ārai i te hanganga o te aukati kia pai ai te ārai i te pēhanga rerekē. Ka taea te tapahi i te wāhi e pā ana ki te pakitara o te puna kia pai ai te whakaiti i te tūponotanga o te hanga aukati pēhanga rerekē. Ko te taumaha o te kara wiri porowhita he 4-6% te iti iho i te taumaha o te kara wiri porowhita.
Kara Wiri Kore-Aukume: He mea hanga ngā kara wiri kore-aukume mai i ngā rauemi kara wiri kore-aukume he iti te kaha mā te whakakotahi i te tātari matū motuhake me te tukanga hanga hama hurihuri me te iti o te uruhanga aukume, he tino pai te kaha mīhini. Ka taea e mātou te whakarato i ngā roa mai i te 10 ki te 42 putu me te diameter o waho mai i te 3 1/8" ki te 11'.
