He aha te mahi a te taika wai waka?
Ko te taika wai waka, e mohiotia ana ko radiator, ko te waahanga nui o te punaha whakamahana waka; Ko te taika wai he waahanga nui o te miihini whakamahana wai, na te mea he waahanga nui o te iahiko whakamahana miihini whakamaarama wai, ka taea te tango i te wera o te poraka porotakaro.
No te mea he nui te kaha o te wera motuhake o te wai, ko te pikinga o te pāmahana i muri i te tango i te wera o te poraka cylinder kaore i te nui, na te wera o te miihini i roto i te wai whakamatao i tenei iahiko wai, te whakamahi i te wai hei kawe wera wera, katahi ka puta i te waahi nui o te totohu wera i roto i te ara o te tohanga wera convection, kia mau tonu ai te pāmahana mahi tika o te miihini.
