Te tatau i te whakamahinga hiko e ngā taputapu hiko - ngā raruraru me ngā otinga
1. I roto i tētahi whare, e 5 ngā rama e 25 Watt e whakamahia ana mō ngā hāora 14 i te rā, he pouaka whakamātao 200 Watt e whakamahia ana mō ngā hāora 24 i te rā, me tētahi papu wai 125 Watt e whakamahia ana mō ngā hāora 8 i te rā. E hia te nui o te pūngao hiko e whakamahia ana mō te marama (30 rā)?
Mōhiotia:
Te mana o te rama = 5(25) = 125 Watts me te wā whakamahi = 14 hāora x 30 = 420 hāora
Te mana o te pouaka whakamātao = 200 Watts me te wā whakamahi = 24 hāora x 30 = 720 hāora
Te mana o te papu wai = 125 Watts me te wā whakamahi = 8 hāora x 30 = 240 hāora
E hiahiatia ana: Pūngao hiko i whakamahia mō te marama
Rongoā:
Pūngao hiko = mana hiko x wā
Pūngao (rama) = (125 Watt)(420 hāora) = 52,500 Watt hāora = 52,5 kiro Watt hāora
Pūngao (pouaka whakamātao) = (200 Watt)(720 hāora) = 144,000 Watt hāora = 144 kiro Watt hāora
Pūngao (papu wai) = (125 Watt)(240 hāora) = 30,000 Watt hāora = 30 kiro Watt hāora
Pūngao hiko e whakamahia ana mō te marama = 52,5 + 144 + 30 = 226,5 kiro Watt hāora = 226,5 kiro Watt hāora = 226,5 kWh.

2. He whare e whakamahi ana i ngā taputapu hiko e ai ki te ripanga e whai ake nei.
E hia te nui o te hiko e whakamahia ana mō te 1 marama (30 rā)?
Mōhiotia:
Te mana o te rama = 4 x 10 Watt = 40 Watt me te wā whakamahi = 10 hāora x 30 = 300 hāora
Te mana o te pouaka whakaata = 1 x 100 Watt = 100 Watt me te wā whakamahi = 10 hāora x 30 = 300 hāora
Te mana o te rino = 1 x 300 Watt = 300 Watt me te wā whakamahi = 2 hāora x 30 = 60 hāora
E hiahiatia ana: E whakamahia ana te hiko mō te kotahi marama
Rongoā:
Pūngao hiko = mana hiko x wā
Pūngao e whakamahia ana e te rama = (40 Watt)(300 hāora) = 12,000 Watt hāora = 12 kiro Watt hāora = 12 kWh
Pūngao e whakamahia ana e te pouaka whakaata = (100 Watt)(300 hāora) = 30,000 Watt hāora = 30 kiro Watt hāora = 30 kWh
Pūngao e whakamahia ana e te rino = (300 Watt)(60 hāora) = 18,000 Watt hāora = 18 kiro Watt hāora = 18 kWh
Pūngao katoa = 12 kWh + 30 kWh + 18 kWh = 60 kWh.

3.
Ko te pūngao hiko e whakamahia ana e ngā taputapu hiko e toru i runga ake nei ko…
A. 158,400 Joules
B. 950,400 Joules
C. 5,860,800 Joule
D. 9,504,000 Joule
otinga
Te mana hiko o te pouaka whakaata:
P = VI = (220 Volt)(0.3 Ampere) = 66 Volt Ampere = 66 Watt = 66 Joule/hekona
Te mana hiko o te rorohiko:
P = VI = (220 Volt)(0.4 Ampere) = 88 Volt Ampere = 88 Watt = 88 Joule/hekona
Te mana hiko o te papu wai:
P = VI = (220 Volt)(0.5 Ampere) = 110 Volt Ampere = 110 Watt = 110 Joule/hekona
Wā ā-wā:
10 hāora = 10 x 3600 hēkona = 36,000 hēkona
6 hāora = 6 x 3600 hēkona = 21600 hēkona
4 hāora = 4 x 3600 hēkona = 14400 hēkona
Pūngao hiko = mana hiko x wā
Pūngao hiko e whakamahia ana e te pouaka whakaata = 66 Joules/hēkona x 36,000 hēkona = 2,376,000 Joules
Pūngao hiko e whakamahia ana e te rorohiko = 88 Joules/hēkona x 21,600 hēkona = 1,900,800 Joules
Pūngao hiko e whakamahia ana e te papu wai = 110 Joules/hēkona x 14,400 hēkona = 1,584,000 Joules
Pūngao hiko katoa:
2,376,000 Joule + 1,900,800 Joule + 1,584,000 Joule = 5,860,800 Joule

4. E whakamahi ana tētahi whānau i te hiko mō te marama (30 rā) mō ngā taputapu pēnei i te ripanga e whai ake nei!
Ko te mana hiko o te mīhini horoi, te pouaka whakaata me te hauhautanga he…
Rongoā:
Pūngao hiko o te mīhini horoi = 12 kWh = 12,000 Watt hāora, te roa o te whakamahinga = 2 hāora x 30 = 60 hāora
Pūngao hiko o te pouaka whakaata = 19.2 kWh = 19,200 Watt hāora, te roa o te whakamahinga = 8 hāora x 30 = 240 hāora
Pūngao hiko o te AC = 72 kWh = 72,000 Watt haora, te roa o te whakamahinga = 6 hāora x 30 = 180 hāora
Mana hiko = pūngao hiko / wā
Te mana hiko o te mīhini horoi = 12,000 Watt hāora / 60 hāora = 200 Watt
Pouaka Whakaata hiko = 19,200 Watts haora / 240 haora = 80 Watts
Mana hiko AC = 72,000 Watts haora / 180 haora = 400 Watts
