1. Mana Whai Hua:E mōhiotia ana hoki ko te mana whakaputa. E pā ana ki te pūngao e whiwhihia ana e te
te wai e rere ana i roto i te papu wai i roto i te wā kotahi mai i te wai
papu
Pe=ρ GQH/1000 (KW)
ρ——Kiato o te wai e tukuna ana e te papu（kg/m3）
γ——Taumaha o te wai e tukuna ana e te papu（N/m3）
Q——Rere o te papu (m3/s)
H——Upoko papu（m)
g——Te whakaterenga o te kaha ā-papa (m/s2).
2. Te Whai Hua
E pā ana ki te ōrau o te ōwehenga o te mana whai hua o te papu ki te mana o te pou, e whakaatuhia ana e η. Kāore e taea te whakawhiti i te mana katoa o te pou ki te wai, ā, ka ngaro te pūngao i roto i te papu wai. Nō reira, he iti iho te mana whai hua o te papu i te mana o te pou. Ko te whai huatanga te tohu o te taumata whai hua o te huringa pūngao o te papu wai, ā, he tohu hangarau me te ōhanga nui o te papu wai.
η =Pe/P×100%
3. Mana o te toki
E mōhiotia ana hoki ko te mana whakauru. E pā ana ki te mana i whiwhihia e te rakau papu mai i te mīhini hiko, e tohuhia ana e P.
PShaft hiko =Pe/η=ρgQH/1000/η (KW)
4. Te mana ōrite
E pā ana ki te mana o te mīhini hiko e ōrite ana ki te papu wai, e tohuhia ana e P.
P(Mana Taurite)≥（1.1-1.2）Mana poutū PS
5. Tere Hurihanga
E pā ana ki te maha o ngā hurihanga ia meneti o te impeller o te papu wai, e tohuhia ana e n. Ko te wae r/min.
