whakaahuatanga
Ko te paera whakaheke pehanga he paera e whakaheke ana i te pehanga uru ki te pehanga putanga e hiahiatia ana ma te whakatikatika, me te whakawhirinaki ki te kaha o te reo ake kia mau tonu ai te pehanga putanga.Mai i te tirohanga o nga miihini wai, ko te puera whakaheke pehanga he huānga kaitahuri ka taea te whakarereke i te aukati o te rohe, ara, ma te huri i te waahi kaitao, ka huri te rere o te rere me te kaha kinetic o te wai, ka puta mai he rereke o te pehanga, na reira ka tutuki. te kaupapa o te whakaheke pehanga.Na, ma te whakawhirinaki ki te whakarereketanga o te punaha whakahaere me te whakarereketanga, ka taurite te rereketanga o te pehanga valve ki te kaha o te puna, kia mau tonu ai te pehanga valve i roto i tetahi awhe hapa.
