Mana Units. DC mana: pa alima

Ua maopopo ka mana i loko o ke kālaikūlohea like me ka lākiō ua ana i loko o kekahi manawa o ka hana a hiki i ka wā o ka manawa no ka i ka mea, ua hana. Ma lalo o mechanical e hana i manaoia ka laupaʻi ke keʻena o ka hopena poe ma ke kino, ma muli o ia a ka hope e neʻe aku i loko o ka lewa.

Oe ke hoike i ka mana, a me ka uku o ka ikehu hoolilo. Ia mea, e hōʻike i ka ka hoʻokōʻana o ka 'akomi mīkini. Ma ana i ka mana ia i ike i ka hana a ua hana koke.

Power huahelu pa alima

Mana ua anaia mai ka manawa i loko o watts a joules no kekona. Motorists ike mana ana ma ka horsepower. Ma ke ala, ma mua o ka Hekikai o ka mahu kiko'ī keia waiwai ua ole ana i nā mea a pau.

I kekahi lā, ka hoʻohana 'ana i keʻano papa hana o ka noʻu, i ka lunaʻenehana George. White i kona hou. E hoao i kona engine hou, ua hoʻokūkū aʻela ia me ka hana ana o ka lio. People Ua hoʻohana ia no kenekulia. No laila kekahi kanaka, he mea paakiki e noonoo ai i na i ka hana o ke kikoo lio no i kekahi wā o ka manawa.

E kiai ana ia ia, White hoohalikeia ka palapala mahu kiko'ī, ke kaumaha ma muli o ka nui o ka horsepower. He experimentally pōpilikia i kekahi lio ka mana o 746 watts. I kēia lā, a pau i hoomaopopoia i keia helu ua maopopo overpriced, akā, me ka mana o ka mokuna hoʻoholo ole i ka hoʻololi 'ana i.

Ma keʻano o ka'ōlelo mai physical nui aʻo e pili ana i ka hana ana, no ka mea maoli i ka hana, piʻi pū no ka ia wā o ka manawa. Oia ke ana hōʻike pa alima o ka ana ua lilo loa, he pono ole. Ua hoomaka ia e hoʻohana 'ia ma ka likeʻole ma o maomeka. Nolaila, a hiki ina ka watts, a ua ua hoʻohana no ka lōʻihi manawa, no ka nui horsepower ka mea, Ua oi maopopo ma mua o ka mea 'ē aʻe mana huahelu.

Pehea e maopopo i ka mana i loko o ka hale pou nā mīkini home

Hila, o ka papa, a me ka hoike ko ka hale ona uila hana. Ma kukui hoʻohana 'ana i kona kekahi cia, no ka laʻana he kanaono watts. Pu u kukui me kekahi ana nui o ka mana, e hookupaa aku ina he mea hiki ole, no ka mea, i ole ia ka mea e koke deteriorate. Akā, ināʻoe i ole kuai i incandescent kukui, a alakaʻi paha kukui hāweo, e e hiki, e haliu oluolu mai me ka nui olinolino, oiai hoopau iki mana mea.

ikehu hokii, o ka papa, Ua pololei hapaʻauhau i ka nui o ka mana. No laila, no ka Manufacturers o ka malamalama pu u kukui mea mau i ke kahua no huahana hou. Currently, nā mea kūʻai mai makemake 'ē aʻe nā koho, koe wale no ka incandescent kukui.

New mana

mana huahelu huahelu i ike ole wale ma ka pili ana i ka lawe ana o maomeka. I ka manaʻo o ka mana hiki e wahi ana i na holoholona, a me kānaka. No ka laʻana, ua nui hiki ke ho omaulia ka wā o ka 'âlapa Ka Wailele O ka mea poepoe a' ē lako a pan, e loaa ia ma ka hopena o ke kukuluia'na o ka pili ikaika, loihi a me ka manawa o kona palapala noi.

Oe ke hiki ke hoʻohana kamepiula papahana me a 'inideka he pōpilikia me he hopena i i kekahi dala o ka hoʻokō' a me ka hoʻokomo 'ia' o ka mea kiko'î.

ana mea

Dynamometer - he kūikawā manaʻo ma i mana ua anaia mai ka manawa. Ka mea, i kekahi hoʻohana e hoʻoholo i ka ikaika a me ka ikehu. Ka mea ua hoʻohana ma o ka likeʻole ma o na hana. No ka laʻana, ka mea, e hōʻike i ka mana o ka engine. E hana i kēia, i ka Hawaii ua wehe 'ia mai i ke kaa, a pili i ka dynamometer. Akā, aia no i na mea maalea mea i hiki ke ho omaulia i ke koi 'ia a hiki ma ka huila.

Ma haʻuki lapaau a me dynamometers i no hoi he ākea. Simulators pinepine i nā mea e loaʻa ka mea nalo i i pili ai i ke kamepiula. Me ia, a me ka hana a pau na ana.

Wattage

James Watt invented ka mahu engine, a me ka mai 1889, he ana o ka mana o ka uila he lilo watts, a me ka wahine nenoaia o ke ana waiwai i komo i loko o ka makahiki 1960.

Ma watts hiki ke anaia ole wale uila akā, i thermal, me mechanical 'ole kekahi' ē mana. Ua Ua hoi pinepine i hanaʻia o kekahi mau a me iiaciiie-o kekahi mau. Ka mea, i kapaʻia ai me ka hou ana i ka palapala olelo okoa prefixes "nā kilo", "mega" "giga", a pela aku.:

• lākou, 1 kilowatt hoʻokahi tausani watts;
• MW 1 miliona watts like, a no laila, ma luna o.

Kilowatt-hola

Ma ka hoʻonohonoho 'Si'ōnaehana ka mea, aohe ana huahelu e like kilowatt-hola. Kēia huahelu o ka'ōnaehana, hoʻolauna e hoike no ka hoopauia ka pila ikehu waho. Ma Rusia ka mea hana me ka GOST 8.417-2002 rula ma ka mokuna mana ana o ka uila papa, a noi 'ana i koho.

Keia pa alima ua pono no ka kakau ana i ka lukuʻia ka pila ikehu. He ka loa kaawale palapala, a paka hooluolu hopena. hiki ke hoʻohana i kekahi mauʻaneʻi, inā e pono ai. Ka mea, ke nana like i watts:

• 1 kilowatt hola o 1000 WH;
• 1 megawatt-hora lākou, 1,000 kilowatt-hora, a no laila, ma luna o.

Full ka inoa ka mea i palapalaia, i ua ike, a me ka hyphen, a me ka pōkole - ma ka wahi (WH, kWh).

I hōʻike i ka uila mana

Ua Ua nui maliuia e hōʻike mai la anakahi 'ana ma luna o ka hale noho o ka pila nui mea paahana. e hiki designations:

• watt me ka kilowatt;
• WH a me kilowatt-hora;
• Volt-Amps a me kVA.

Ka loa ao hōʻailona o ka hoʻohana 'ana o ia mau huahelu i watts a me kilowatts. Inā kekahi hiki ke i ma luna o ka mokuna manao i keia mana ua hoʻomohala i loko o kēia lako a pan.

Pinepine aku ma watts a me kilowatts ana me mechanical mana uila nā mīkini uila a me Hawaii, thermal mana uila heaters, a no laila, ma luna o. D. kēiaʻano nuiʻikena mana pa alima i loko o ka mea i ua hoʻomōhala kuhikuhi ma ka nui o ka ua loaʻa wela, a ua lawe i nā helu i mooolelo mua ma hope ona.

Watt-hola a me kilowatt-hora hōʻike i ka mana hokii no ka haawi pa alima o ka manawa. Pinepine mau designations hiki ke ike ia ma ko ka hale ona pou nā mīkini home.

Ma ka hoʻonohonoho ' Si'ōnaehana he uila mana huahelu, a e like me watts a kilowatts - he volt-amperes a me KVA. Oia ka huahelu eaaaony no ka heluhelu ana o AC mana. Ka mea, i hoʻohana 'ia i loko o oaoieei-ho ka wā nui pou kiko'î.

Oia inoa maikai fits nā koi o ka pou 'enekinia,, kahi mea maalea, e hana me ka alternatingʻikena, nō nā ikehuʻeleu, a kū'ē. Nolaila, uila mana ua nānā 'ana i ka huina o kēia mau eiiiiiaiou. Pinepine ma VA Kû ke mana i punihei e like me transformers, inductors, a me nā converters.

Ma ka Ia Hookah E waeʻoukou i i ÷ naehana ana e koho 'ia, me ka nui no laila, i loko o ka hihia o ka haʻahaʻa-mana lako a (ka mea e, no ka laʻana, ko ka hale ona pou nā mīkini home), a pau ekolu designations kamaʻilioʻana i ka coincide.
