Tikanga mahi mo te wa whakawhiti
Tikanga o te Ine:
Ko teTe wa whakawhitiKo te Tikanga Whakataurite ka whakamahi i te meka ko te wa-o-rere o te tohu ultrasonic e pa ana ki te tere rere o te reo kawe.Ka rite ki te kaikauhoe e haere ana ki te taha o te awa e rere ana, he puhoi ake te haere o te tohu ultrasonic ki runga ake i te awa.
To tatouTF1100 mita rere ultrasonicmahi i runga i tenei tikanga whakawhiti-kokokota:
Vf = Kdt/TL
Kei hea:
VcRere tere
K: Tonu
dt: He rereke te wa rere
TL: Ave riri Te Wa Whakawhiti
Ka mahi ana te mita rere, ka tukuna e nga kaiwhakawhitiwhiti e rua nga tohu ultrasonic kua whakanuia e te kurupae maha ka haere tuatahi ki raro, ka whakarunga ki runga.Na te mea ka tere ake te haere o te oro ultra ki raro i te awa whakarunga, ka rereke te waa rere (dt).Ina noho tonu te rere, he kore te rereketanga o te wa (dt).No reira, i te mea e mohio ana tatou ki te wa rere ki raro me te whakarunga o te awa, ka taea e tatou te whakatau i te rereketanga o te wa, katahi ka te tere rere (Vf) ma te tauira e whai ake nei.
