Units Power. DC kaha: kōwae

i matau Power i roto i te ahupūngao te rite oti te ōwehenga i roto i te tetahi wa o mahi ki te wā o te wa mo nei whakamana ai. I raro i te mahi aunoa tikanga o te wāhanga ine o te tōpana pānga i runga i te tinana, e tika ana ki nei te nekehanga muri i roto i te wāhi.

Ka taea e koe te faaite i te mana, me te rite te auau o te whakawhitinga pūngao. Ko, whakaatu reira te tōtika o te mīhini aunoa. Mā te ine i te kaha riro te reira mārama pehea hohoro mahi te mahi te.

wae Power inenga

whanganga Power Kei roto i Watts joule ia te rua ranei. Kaitaraiwa mohiotia te mana inenga i roto i horsepower. E te ara, i mua i te taeraa mai o engines korohū kore te tenei uara whanganga i te katoa.

Kotahi ra, mā te whakamahi i te huarahi o te aku, te kaipūkaha George. White ka mau tona whakapai ake. Hei whakamatau i tana whakapai ake engine whakaritea e ia taua mea ki te mahi o hoiho. Kua whakamahia ratou iwi mō ngā rau tau. Na reira i ngāwari ki te whakaaro i te mahi o nga hoiho hukihuki mō te tetahi wā o te wā te tangata.

Mātakitaki ratou, whakaritea White nga engines tauira mamaoa, i runga i te nui o horsepower rānei. Ia experimentally tatau e tetahi mana hoiho ko 746 Watts. I teie mahana, he whakaaro katoa e te mārama overpriced tenei tau, engari faaoti te wae te mana kore ki te huri i.

Na roto i te inenga ā-mea ako e pā ana ki te mahi, mai i faarahi te reira i te piki mahi mo te wā ano o te wā. riro te wae paerewa pērā o te inenga kua tino noa. ka anga te reira ki te kia whakamahia i roto i te whānuitanga o tikanga. Na reira, ara, ki te mea kua kua whakamahia te Watts, me mo te wa roa, mo te tokomaha horsepower ko reira atu mārama atu te tahi atu wae mana.

Me pēhea te ki te matau i te mana i roto i te whare taputapu hiko

Power, o te akoranga, tohu me te whare machinery hiko. I roto i te rama whakamahi ona uara motuhake, hei tauira e ono tekau Watts. Topuku ki te mehua nui o te mana ki te whakapumautia ki he e taea, no te mea te kore hohoro ratou e tupuheke. Otiia ki te kahore koutou i hoko i te rama aano atu, ka arahina kōrekoreko ranei, ka taea ki te tiaho ki te tiaho nui, i te kai iti te kaha ratou.

kohi pūngao, o te akoranga, ko te tika hautanga ki te nui o te kaha. Na reira, hoki kaiwhakanao o topuku marama ko tonu he mara hei whakapai ake hua. I tēnei wā, kiritaki hiahia atu kōwhiringa, ki te kahore hoki rama aano atu.

mana Sport

E mohiotia wae mana inenga kore anake i roto i te hononga ki te whakamahi o tikanga. Ka taea te pēnei te ariā o te kaha ki te kararehe, me te ki te tangata. Hei tauira, e taea te tatau i tenei uara ina whiua te kaipara he pōro atu taputapu ranei ki te whiwhi i te reira rite ki te hua o te whakatūnga o te tōpana, tawhiti, me te wa o tona tono.

Ka taea e ara e koe te whakamahi i ngā hōtaka rorohiko me i tātai taupū te rite ki te hua i hanga he nui etahi o mahi, me te introduction o ngā tawhā.

ine mea

Dynamometer - he pūrere motuhake e ai whanganga mana te. Kei te whakamahia hoki ratou ki te whakatau i te kaha me te taipana. whakamahia te mea i roto i te whānuitanga o ngā ahumahi. Hei tauira, whakaatu e ratou te kaha o te pūkaha. Ki te mahi i tenei, nekehia atu te pūkaha e i te waka, ka hono ki te dynamometer. Ko reira he whakaaro e e taea ki te tātai i te hiahiatia noa i roto i te wira.

I roto i te rongoā hākinakina me dynamometers he whānui hoki. maha i pūoko e kua hono ki te rorohiko simulators. Ki a ratou, a ka meinga nga inenga katoa.

Wattage

James Watt whakaaro te pūkaha mamaoa, a mai i 1889, he mehua o te kaha o te nāianei hiko ka Watts, me te pūnaha ao o te uara inenga ngā i roto i te tau 1960.

I roto i te Watts taea ana te ruri te tahi atu mana hiko engari ano waiariki, pūkaha tetahi ranei e kore e anake. Kei te maha te reira i hanga ano taurea me ngā taurea-iho. E huaina ratou ki te tua ki te kupu taketake rerekē arohere "kiro", "mega" "Giga", aha atu.:

• 1 kirowati ōrite kotahi mano Watts;
• MW 1 miriona Watts rite, me te pera i runga i.

Kirowati-haora

I roto i te pūnaha SI ao i reira he kahore wae inenga rite kirowati-haora. Ko waho o te pūnaha, whakaurua ki te pūkete mō te pūngao hiko pau tenei ahua. I roto i te Russia mahi reira ki GOST 8.417-2002 ture i reira tono whakaritea tika te wae te mana inenga o te nāianei hiko, me te.

Kei te tūtohutia tēnei kōwae mō te rēhitatanga o pau pūngao hiko. Ko te reira i te puka tino watea, e hua hua manakohia. taea hoki te whakamahi taurea konei, ki te tika. titiro ratou rite ki Watts:

• 1 kirowati haora ko 1000 Te Ranga Takapau;
• 1 megawatt-haora ōrite 1,000 kirowati-haora, a pera i runga i.

ingoa Full te tuhituhi, rite kite kua, ki te tohuwehe, me te poto - i roto i te pūwāhi (Te Ranga Takapau, kWh).

Ka rite ki tohua i roto i te mana hiko

E whakaaetia whānuitia ana ki te tohu tika tohu mea i runga i te whare o te taputapu hiko. He taea iku'anga:

• Watt me kirowati;
• Wh me kirowati-haora;
• Wae ngaohiko-Amps me kVA.

Ko te tohu ao tino ko te whakamahi o taua wae rite Watts watt ranei. Ki te taea te hanga tetahi ki runga ki te kōwae mutu i whakawhanakehia tenei mana i roto i tenei taputapu.

E mea pinepine i roto i te Watts me watt whanganga mana mīhini generators hiko me motors, waiariki mana hatete hiko, me te pera i runga i. D. E pā ana wae mana te nuinga o nāianei i roto i te pūrere arotahi nei te matua i runga i te nui o te wera i hanga, a kua tangohia te tātai ki pūkete kua i muri ia ia.

Watt-haora, me te kirowati-haora whakaatu te kohi mana mo te kōwae i homai o te wā. Pinepine e taea te kite i enei iku'anga i roto i taputapu hiko whare.

I roto i te ao pūnaha SI he wae mana hiko, e he ōrite ki Watts me watt - he wae-amperes me KVA. he inenga taua whakarato mo te pānui o AC mana. E whakamahia ratou i roto i ngā tātai hangarau ka tawhā hiko nui.

Taua ti'araa pai hāngai te whakaritenga o engineering hiko, te wahi whakaaro e mahi ki tauutuutu nāianei, ko e rua pūngao mātātoa, me te urupare. Na reira, te mana hiko e whakaritea e te moni o enei wae. E mea pinepine i roto i VA rawea, whakaaro mana pērā i transformers, inductors, me ētahi atu pūtahuri.

I te i ma'iti o kaihanga taua nei ki ngā wae o inenga whakapūtā reira, te atu pera i roto i te take o te taputapu mana-iti (nei e, no te tauira, te whare taputapu hiko), katoa iku'anga e toru ahu ki te hāngai.
