WHAKAMĀRAMA

Ko te āhei o tētahi rauropi, o tētahi pūrere rānei ki te whakaiti i te pūngao moumou ka puta i a ia. He inenga o te hautanga o te pūngao ka uru ki tētahi rauropi, ki tētahi pūrere rānei, ka hurihia hei pūngao whaihua.

The ability of an organism or an appliance to reduce the waste energy that it releases. A measure of the proportion of the energy input of an organism or an appliance that is transformed to useful energy.

Tauira KŌrero

Me pēhea te tātai i te whāomotanga pūngao o te pūrere horoi kaka?

Rārangihia ngā huarahi hei whakapiki i te whāomotanga pūngao o tētahi pūrere.

Kāore e tino rahi te whāomotanga pūngao o te nuinga o ngā pūrama – he nui te pūngao moumou.

WhakamĀrama Āpitihanga

Koia nei te ture mō te pūmau o te pūngao:

pūngao uru = pūngao puta

Ko tētahi wāhanga o te pūngao puta ko te pūngao moumou, ko tētahi wāhanga ko te pūngao whaihua e tutuki ai te mahi a te pūrere, a te rauropi rānei. Nō reira:

pūngao uru = pūngao puta
= pūngao whaihua + pūngao moumou

Hei tauira, ko te pūngao puta o tētahi pūrama, 100W te kaha:

Ia hākona, 60J te rahi o te pūngao hiko ka whakaurua ki te pūrama 60W te kaha.

Ka hurihia taua pūngao e te pūrama. 6J te rahi o te pūngao aho (he whaihua), 54J te rahi o te pūngao pōkākā (he moumou), ka whakaputaina i ia hākona.

Ka tātaihia te whāomotanga pūngao o te pūrama mā te tātai i te ōrau:

Hei tauira o te whāomotanga pūngao o ētahi atu pūrere:

Te pūrere	Te whāomotanga pūngao
he pūkaha kōhinu o tētahi motukā	15%
he pūkaha hiko o tētahi tereina	35%
he punahiko waro koranehe	35%
he punahiko hau	40%
he punahiko wai	80%
he pahikara	90%
