Me pēhea te ki te kitea te mana i roto i ngā āhuatanga rerekē?

I roto i te ora, i ētahi wā i reira he āhuatanga ka ki te hiahia akiaki whakaoti i te raruraru e pā ana ki te pehea, ki te kitea te mana, e ko, te uara e pā ana ki te kāwai o te mahi me te wā. He nui tēnei tautuhinga tinana no te mea taea reira ki a koe te tautuhi i maha uara. Hei tauira, ka taea e te mea ohie ki te tātai i te wa hoki e ka meinga kia he mahi tomu'a. Ia whakaahua ana ano, i te pānga, o te akoranga, te mahi o ngā momo rerekē o engines. I hoki e taea te whakaritea te pūtake o tenei uara, hei tauira, wahie kohi. Ko, he mea nui, mo te ahupūngao me te mo te ōhanga e rua. Na reira, ko te taumira o ngā take e pā ana ki te pehea, ki te kitea te mana, E auraa rahi to mahi, me te mahi.

wae

Conventionally, te wae te mana e taea te wehea ki nahanaha, me te kore-nahanaha. I roto i te take tuatahi, Watts reira (W W ranei) me te raupapa o taurea me submultiples, iku'anga o nei e hanga e mā te tāpiri i te pīmua ki te pūtake i runga ake. Hei tauira, watt - he kotahi mano Watts. I runga i te taumata tinana, kōwae tenei faaite te mahi ki te kia meatia i roto i te wā wā. te whānui tino pera-ka karanga "horsepower" i roto i ngā waeine pūnaha-kore. Ko tenei no te mea whanganga te mana o te nuinga o te ngingiha pūkaha ā o teie mahana te i roto i enei wae. Te hononga e whai ake nei i waenganui i a ratou - kotahi horsepower he 735 Watt me te hawhe. Kia faaoti matou i runga i te wae i roto i nei whanganga te he tawhā tinana, whakautu ki te pātai e pā ana ki te pehea, ki te kitea te kaha i roto i te ahupūngao me te hikohiko.

ahupūngao

Power i roto i te ahupūngao tika hono ki tētahi atu tawhā nui - mahi. Ka rite ki te tohu e tika ana te wā kaimahi. Ka rite ki taua, e taea te whakaritea mana e te mahi e mahia nei i hoki tetahi wā o te wā. No reira tātai mō te mana te tātai, i te mea e whai ake: N = A / t. I roto i tenei tātai, te momotuhi whai ake: N - wae mana i roto i te pūnaha, A - mahi, whanganga i joule, t - te wa i roto i hēkona. Na, whakaatu ana te te nui e hiahiatia ana o mahi, a ka tohu N taua wahi o reira, ki te kia whakamana o te katoa, ki te whai wa ki te hanga i taua mea i runga i te t wā.

engineering hiko

I roto i te engineering hiko, pērā te ahupūngao, he nui māmā mea katoa. Rua i roto i te ariā me te i roto i te mahi. Takahi, te tawhā taua whakaritea e te hua o nga uara motuhake o nāianei , me te ngaohiko. Ko, te tātai, ko te P = U * I. wahi P - ko te mana ki te katoa o te wattage kotahi. U - ngaohiko, whanganga i volts, me ahau - nāianei i roto i amperes. He ao te tātai, he tika hoki e rua DC me AC e te hoatu faaiteraa. Ki reira ka taea e ngāwari koe te whakatau i te nui o te mana ki tetahi pūrere. Ano, i roto i te mahi, anake kotahi pūrere - te mita. Tuatahi, tautuhi nga inenga whakarara te ngaohiko, a ka te rangatū - nāianei. E mea pinepine, tenei ara e taea e kitea e koe i te whakahoki ki te pātai o te pehea, ki te kitea e te mana o te pūkaha. Tērā, pänuitanga taea hoki wattmeter tono. Ko Ko te tino utu tenei taputapu ine, mo tenei take, e kore te mea te reira ano whānui. Otiia kua riro multimeters wahi o to tatou oraraa, me nga ra e te whakamahia piki. E hoki ratou ringa rehe e nui e titore ratou ki ētahi atu pūrere, e e tino motuhake.

whakarāpopototanga

tauturu te tuhinga ki te whakahoki i te pātai o te pehea, ki te kitea te kaha i roto i te ahupūngao me te engineering hiko. I roto i ngā mahi, i roto i te hikohiko tenei tuu māmā te rota ki te tautuhi. Otiia, ki te hiahia koe mā te whakamahi i te tikanga hangarau hou e taea te whakaoti i tetahi mahi, i roto i te mea ruri.
