Nga Tatautanga Math Pungao Hau
- Te Inenga i te Rohe Hurihia o To Turbine Hau
Te kaha ki te ine i te waahi kua tahia ohe mea nui o matatahi ki te hiahia koetātarihia te kaha o to hurihanga hau.
Ko te waahi kua tahia e tohu ana ki te waahi o teporowhita i hangaia e nga matatahi rite ratoutahia i te hau.
Ki te kimi i te waahi kua tahia, whakamahia te tauawhārite ka whakamahia e koe ki te kimi i te horahangao te porowhita ka kitea ma te whai
whārite:
Rohe =πr2
-
π = 3.14159 (pi)
r = pūtoro o te porowhita. He rite tenei ki te roa o tetahi o ou matatahi.

- He aha te take he mea nui tenei?
Me mohio koe ki te waahi kua tahia o to rohehurihanga hau ki te tatau i te tapeke mana i roto i tehau e pa ana ki to turbine.
Kia mahara ki te Mana i roto i te Wharite Hau:
P = 1/2 x ρ x A x V3
-
P= Hiko (Watts)
ρ= Kiato o te rangi (tata ki te 1.225 kg/m3 i te taumata o te moana)
A= Horahanga Matatahi (m2)
V= Te tere o te hau

Ma te mahi i tenei tatauranga, ka taea e koe te kite i te katoa o te kaha o te kaha o te waahi o te hau. Ka taea e koe te whakataurite i tenei ki te nui tonu o te hiko e mahia ana e koe me to hikohiko hau (me tatau koe ma te whakamahi i te mita maha—whakareatia ngaohiko ki te amperage).
Ko te whakatairite o enei whika e rua ka tohu i te pai o to hurihanga hau.
Ko te tikanga, ko te kimi i te waahi o to turbine hau he waahanga nui o tenei wharite!
