Ka helu ʻana o ka hoʻohana ʻana i ka ikehu uila e nā mea hana uila - nā pilikia a me nā hoʻonā
1. I loko o kahi hale, aia he 5 mau kukui 25 Watt i hoʻohana ʻia no 14 mau hola i ka lā, kahi pahu hau 200 Watt i hoʻohana ʻia no 24 mau hola i ka lā, a me kahi pamu wai 125 Watt i hoʻohana ʻia no 8 mau hola i ka lā. ʻEhia ka nui o ka ikehu uila i hoʻohana ʻia no hoʻokahi mahina (30 mau lā)?
ʻIke ʻia:
Mana o ke kukui = 5(25) = 125 Watt a me ka manawa hoʻohana = 14 hola x 30 = 420 hola
Ka mana o ka pahu hau = 200 Watts a me ka manawa hoʻohana = 24 hola x 30 = 720 hola
Ka mana o ka pamu wai = 125 Watts a me ka manawa hoʻohana = 8 hola x 30 = 240 hola
Makemake ʻia: Ikehu uila i hoʻohana ʻia no hoʻokahi mahina
Lōlā:
Ikehu uila = mana uila x ka wā manawa
Ikehu (kukui) = (125 Watt)(420 hola) = 52,500 Watt hola = 52,5 kilo Watt hola
Ikehu (pahu hau) = (200 Watt)(720 hola) = 144,000 Watt hola = 144 kilo Watt hola
Ikehu (pamu wai) = (125 Watt)(240 hola) = 30,000 Watt hola = 30 kilo Watt hola
Ikehu uila i hoʻohana ʻia no hoʻokahi mahina = 52,5 + 144 + 30 = 226,5 kilo Watt hola = 226,5 kilo Watt hola = 226,5 kWh.

2. He hale e hoʻohana ana i nā mea hana uila e like me ka mea i helu ʻia ma ka papa ma lalo nei.
ʻEhia ka nui o ka ikehu uila i hoʻohana ʻia no 1 mahina (30 lā)?
ʻIke ʻia:
Mana o ke kukui = 4 x 10 Watt = 40 Watt a me ka manawa hoʻohana = 10 hola x 30 = 300 hola
Mana o ke TV = 1 x 100 Watt = 100 Watt a me ka manawa hoʻohana = 10 hola x 30 = 300 hola
Mana o ka hao = 1 x 300 Watt = 300 Watt a me ka manawa hoʻohana = 2 hola x 30 = 60 hola
Makemake ʻia: Hoʻohana ʻia ka ikehu uila no 1 mahina
Lōlā:
Ikehu uila = mana uila x manawa
Ka ikehu i hoʻohana ʻia e ke kukui = (40 Watt) (300 hola) = 12,000 Watt hola = 12 kilo Watt hola = 12 kWh
Ikehu i hoʻohana ʻia e ke TV = (100 Watt) (300 hola) = 30,000 Watt hola = 30 kilos Watt hola = 30 kWh
Ka ikehu i hoʻohana ʻia e ka hao = (300 Watt) (60 hola) = 18,000 Watt hola = 18 kilo Watt hola = 18 kWh
Ka ikehu holoʻokoʻa = 12 kWh + 30 kWh + 18 kWh = 60 kWh.

ʻO ka ikehu uila i hoʻohana ʻia e nā mea hana uila ʻekolu i luna nei…

B. 950,400 Joule
C. 5,860,800 Joule
D. 9,504,000 Joule

Mana uila o ke TV:
P = VI = (220 Volt)(0.3 Ampere) = 66 Volt Ampere = 66 Watt = 66 Joule/kekona
Mana uila o ke kamepiula:
P = VI = (220 Volt)(0.4 Ampere) = 88 Volt Ampere = 88 Watt = 88 Joule/kekona
Mana uila o ka pamu wai:
P = VI = (220 Volt)(0.5 Ampere) = 110 Volt Ampere = 110 Watt = 110 Joule/kekona
Ka wā ma waena:
10 hola = 10 x 3600 kekona = 36,000 kekona
6 hola = 6 x 3600 kekona = 21600 kekona
4 hola = 4 x 3600 kekona = 14400 kekona
Ikehu uila = mana uila x manawa
Ka ikehu uila i hoʻohana ʻia e ke TV = 66 Joules/kekona x 36,000 kekona = 2,376,000 Joules
Ikehu uila i hoʻohana ʻia e ke kamepiula = 88 Joules/kekona x 21,600 kekona = 1,900,800 Joules
Ka ikehu uila i hoʻohana ʻia e ka pamu wai = 110 Joules/kekona x 14,400 kekona = 1,584,000 Joules
Ka huina ikehu uila:
2,376,000 Joules + 1,900,800 Joules + 1,584,000 Joules = 5,860,800 Joules

4. Hoʻohana kekahi ʻohana i ka ikehu uila no hoʻokahi mahina (30 mau lā) no nā mea hana e like me ka papa ma lalo nei!
ʻO ka mana uila o ka mīkini holoi, TV a me ka AC…
Lōlā:
Ikehu uila o ka mīkini holoi = 12 kWh = 12,000 Watt hola, manawa hoʻohana = 2 hola x 30 = 60 hola
Ikehu uila o ke TV = 19.2 kWh = 19,200 Watt hola, manawa hoʻohana = 8 hola x 30 = 240 hola
Ikehu uila o AC = 72 kWh = 72,000 Watt hola, manawa hoʻohana = 6 hola x 30 = 180 hola
Mana uila = ikehu uila / manawa
Mana uila o ka mīkini holoi = 12,000 Watt hola / 60 hola = 200 Watt
Mana uila TV = 19,200 Watt hola / 240 hola = 80 Watts
Mana uila AC = 72,000 Watt hola / 180 hola = 400 Watts
