Bala Watts eziningi kanjani KW ngayinye

Uma unesithakazelo umbuzo Watts eziningi kanjani KW ngayinye, impendulo uzothola, ngemva kokufunda lesi sihloko. Kuyini Watt? Lokhu iyunithi amandla nesilinganiso ezamukelwe ngu International wokulinganisa simiso amayunithi (SI). It wathola igama layo ngenxa umakhenikha-umsunguli abadabuka Scotch-Irish uJames Watt, odale jikelele umusi injini. Kuze 1882 lapho iningi nemizana amahhashi wawuyisikhungo lisisakhiwo zokulinganisa, futhi kuphela emva Mechanics okusungulile yonke indawo (ikakhulukazi kwezobunjiniyela kagesi) yokutholwa iyunithi entsha kwamandla - Watts. Ngo-physics, amandla ukusetshenziswa energy of inqubo iyunithi isikhathi ngasinye, ngokulandelana, uyoba lingana kuze fike watt eyodwa joule ngomzuzwana (W = J / s).

Bangaki Watts e kilowatts

Abantu njalo sibhekene nomqondo amandla kagesi ekhaya. Zonke zikagesi passport isethelwe ukusetshenziswa amandla. Ngisho ngesikhathi aphansi esikhipha isibani, ebhodleleni ebhaliwe .. 40 W, 60 W, 100 W, njll Ngokuqondene microwave oven noma umshini wokuwasha, ukubaluleka ubhekwa kakhulu kunalokhu: 500-1000 W futhi 2-2, 5 kW, ngokulandelana. Njengakwamanye amagugu ngokomzimba, isiqalo "ikhilo" kusho ayinkulungwane aphindekile. Okungukuthi, abangabantwana value kwamanani kwamandla ulinganiswa kilowatts, Wandisa ngo-1000 noma ukuhambisa iphuzu ledesimali uphawu kwesokudla amadijithi amathathu: ngakho sithola kagesi amandla value Watts.

Ngakho, umbuzo bangaki Watts kilowatts, sathola impendulo isobala: KW e eziyinkulungwane Watts (1 kW = 1000 W). iimbonelo ukuhlaziya kagesi power ukurekhoda. Nazi izibonelo ezimbalwa zendlela ukuhumusha amagugu wabonisa:

• 2.5 kW = 2500 Watts.
• 0.2 kW = 200 Watts.
• 3.095 kW = 3095 Watts.

Kwesinye isikhathi kudingeka amandla iyunithi, obonakaliswe Watts, iguqulwe ukuze kilowatts. Siyaye sijabule lapho sikhumbula Watts eziningi kanjani ngalinye kilowatt ke eyaziwa ukubaluleka ehlukaniswa eziyinkulungwane. Kuphakathi ukhefana aphathekayo amadijithi amathathu kuya kwesokunxele.

• 2750 W = 2.7 kW.
• 70 W = 0,07 kW.
• 150 W = 0.15 kW.

Ake sicabangele into efana "-hora kilowatt"

Kilowatt amahora (noma watt amahora) kukalwa the kagesi amandla ukusetshenziswa per unit ihora. Njengoba isibonelo, ukuthatha ikhompyutha ezivamile nge amandla 0.65 kW. Ake ucabange ukuthi basebenze ihora linye. Ngazi kanjani ukuthi angakanani amandla lapho wazinikela ngalesi sikhathi? Silula: 0,65 kW iphindwe 1 ihora, 0.65 ngesenti elilodwa. Ejwayelekile stovattnaya isibani, ihora elilodwa kudle Watts 100 kwamandla, Ngakho-ke, ngosuku wokusebenza okuqhubekayo ke uzochitha 2.4 kW. Bangaki Watts kW, siye kakade okuxoxwe ngawo ngenhla.

yasendlini Basic abathengi kagesi

Njengamanje, ngisho abantu abacebile ngacabanga ukonga amandla - zenqaba incandescent ama futhi esikhundleni sawo ukonga amalambu noma diode ukukhanya-likhipha. Uma ukhetha ikhaya lisebenze ipharamitha main, okuyinto ikakhulukazi aveze izenzo kahle zikagesi. ungathola imishini enjalo endlini ngayinye noma ifulethi, isiqandisi, ithelevishini, i-computer, i-iron, iketela kagesi. Cabanga ngamandla ukusetshenziswa amayunithi okukhulunywa. Seziqa ngokuvamile usebenza ubusuku nemini, layo energy ukusetshenziswa izinga amabanga kusuka 0.7 kuya 1.3 kW ngelanga - ke kuzoncika ubukhulu zedivayisi kanye lokushisa kuma. Ikhompyutha, inqobo nje uma engenzi ukuvala ngoba usuku ungachitha kuze kube 13.5 kW. TV efanayo ukusetshenziswa isilinganiso 2.5 kW amahora angu-24. Nokho, "Abasebenzisa" wukuntuleka Ukushisa Imishini: kettles kagesi, ama-heater amanzi, endzaweni lephephile kagesi kanye nabanye. Ngokwesibonelo, i yokucela kagesi imizuzu 20-25 ibusa 1-1.2 kW, okuyinto ingafaniswa esiqandisini ngokuqhubekayo ukusebenza. Futhi ukuthi angakanani amandla ukusebenzisa?
