Helu ehia na watts no kW

Inā 'oe e hoihoi i loko o ka ninau o ehia na watts no kW, no ka pane' oe e loaʻa, ma hope heluhelu i kēia 'atikala. He aha ka Watt? Kēia mokuna mana ana aponoia ma ka International ana'ōnaehana o ka huahelu (Si). Ua loaa kona inoa ma muli o i ka mechanic-inventor o Scotch-Ipelana kuauhau James Watt, ka mea i hana i ka ao mahu engine. A 1882 ka wā ka hapanui o na Luna Hooponopono ma horsepower i hoʻohana like me ka walaʻauʻana pa alima o ke ana, a ma hope wale nō o ka hana mea hou i hana muaʻole mechanics wahi (oi loa aku hoi i ka uila 'enekinia,) hoohana i ka hou pa alima o ka mana - watts. Ma ke kālaikūlohea, ka mana o ka ikehu hoopau ana o ke kaʻina hana no ka mokuna o ka manawa, pakahi, e like me kekahi watt kekahi joule no kekona (W = J / s).

Ehia na watts ma kilowatts

People i mauʻalo i ka manaʻo o ka uila mana i loko o ka hale. All nā mīkini home i loko o ka palapala holo'āina'ē ua hoonoho i ka mana hokii. Pela hoi, aole i ka mea haʻahaʻa incandescent u kukui, i loko o ke aniani alabata palapala .. 40 W, 60 W, 100 W, etc. E like no me ka hawewe umu a me ka holoi ana mīkini, i ka waiwai ua manaoia e e nui maluna: 500-1000 W a me 2-2, 5 kW, niioaaonoaaiii. Like i loko o nā physical Hawaiʻi, ka pākuʻina kau "nā kilo" 'o ia hoʻi he tausani pa. Ia mea, me ka laulā cia o ka mana ana i loko o kilowatts, e e hoonuiia ka 1000 a ka neʻeʻana i nā kekimalaʻoi ma ka hoailona akau ekolu huahelu: no laila e hele mākou i ka uila mana cia ma watts.

Ke'ī mai, i ka ninau o ehia na watts kilowatts, loaa mai mākou he unequivocal ka pane: i hoʻokahi tausani watts (1 kW = 1000 W) kW. Hou examples kālailai uila i hoʻopaʻa 'ia ka mana. Eia nō kekahi mau examples o ana i ka unuhi i ka hōʻike nā loina:

• 2,5 kW = 2500 watts.
• 0.2 kW = 200 watts.
• 3.095 kW = 3095 watts.

I kekahi manawa, ke koi 'ia ka mana o ka mokuna, i olelo ia i loko o watts, huli i kilowatts. E hoomanao iho la i na mea he nui watts no kilowatt no ia mea, ike waiwai i puunaueia e kekahi tausani. Kekahi i kekahi comma lawe i ekolu huahelu ma ka hema.

• 2750 W = 2,7 kW.
• 70 W = 0,07 kW.
• 150 W = 0,15 kW.

E mākou noonoo ia i kekahi mea e like me "kilowatt-hola"

I kilowatt hola (ole watt hola) ua anaia mai ka manawa ma ka uila mana hokii no pa alima hora. Me lakou i mea hoike, lawe i kaʻike mau kamepiula me ka mana o ke 0,65 kW. E mākou kuhi ana ia hana hoʻokahi hola. Pehea la au e ike i ka nui o ikehu, ua hoolilo ia i keia manawa? Loa puni hoʻi: 0,65 kW hoonuiia ka 1 hora, 0,65 kWh. Mau stovattnaya u kukui, hoʻokahi hora hoʻopau 100 watts o ka mana, nolaila, o ka la o ke ana hana ia, e pana aku au i 2.4 kW. Ehia na watts kW, ua ua kūkā mai nei ma luna.

XIX. Hale pou nā mea kūʻai mai

I keia, hoomaka ae la a hiki waiwai kanaka i manaʻo e pili ana i ikehu makauliʻi - ka mea hoole i ka incandescent pu u kukui, a puku ia me ka hoʻokele waiwai malamalama pu u kukui a me ka malamalama-K'lauea diode. I ka wa e koho i ka papa kuhikuhiE aiao home o mea hāpai mīkini, i pakahi aku la ia kuhikuhi mai hana ka hoʻokōʻana nā mīkini home. oe ke huli i na lako a pan i loko o kēlā me kēia hale a keʻena, Pahu Hau, kīwī, kamepiula, ka hao, ka pila ipu lepo. E hoomanao i ka mana hokii i oleloia huahelu. Pahu Hau nō kāu hana a puni i ka huahelu, kona ikehu hokii kōmi papa koa mai 0,7 e 1,3 kW no lā - ia e hilinaʻi ma ka nui o ka manaʻo, a me ka Ambient mahana. Kamepiula, aka i ka mea, aole i huli aku ai no ka lā hiki ke lilo mai i 13.5 kW. TV hookahi awelika hokii o 2,5 kW no ka 24 hola. Naʻe, i ka "spenders" nui i paio hahana maoli nō nā mīkini home: uila ipu lepo, ka wai heaters, uila cookers a me na mea e ae. No ka laʻana, he uila ipu lepo no 20-25 minuke i pau ai 1-1.2 kW, i hiki ke hoohalikeia me ka noke hana Pahu Hau. A pehea ka nui o ikehu oe hoolilo?
