Werengerani Watts angati pa KW

Ngati mukufuna funso Watts angati pa KW, yankho mudzapeza, nditawerenga nkhani imeneyi. Watt ndi chiyani? Izi mphamvu wagawo muyeso anatengedwa ndi bungwe la International chingwe dongosolo mayunitsi (SI). Dzina limeneli chifukwa makaniko-anayambitsa Sikochi wapa-Irish mbadwa James Watt, amene analenga injini chilengedwe nthunzi. Mpaka 1882, pamene ambiri a m'midzi mu ndiyamphamvu ntchito ngati unit zoyambirira za muyeso, ndipo patapita kuyambitsa zimango kulikonse (makamaka okonza magetsi) anatengera latsopano botolo la mphamvu - Watts. Mu sayansi, mphamvu ndi mowa mphamvu ya ndondomeko pa botolo la nthawi, motero, adzakhala wofanana Watt wina joule limodzi pa mphindi (W = J / s).

Kodi Watts ambiri kilowatts

Anthu zonse anakumana ndi lingaliro la mphamvu ya magetsi panyumba. zipangizo zonse pasipoti uli woikidwa ndi mowa mphamvu. Ngakhale pa pulayimale incandescent babu, mu botolo galasi olembedwa .. 40 W, 60 W, 100 W, etc. Koma uvuni mayikirowevu kapena makina ochapira, phindu imatengedwa kukhala apamwamba: 500-1000 W ndi 2-2, 5 kW, motero. Monga makhalidwe ena thupi, ndi manambala oyambirira "kilo" limatanthauza khola zikwi. Ndiko kuti, phindu n'zosangalatsa kumva za mphamvu amayezedwa kilowatts, kuchulukitsa ndi 1000 kapena kusuntha mfundo decimal kuti chizindikiro lamanja manambala atatu: kotero ife tifike mphamvu ya magetsi phindu Watts.

Choncho, funso mmene Watts ambiri kilowatts, tinalandira yankho wopezeka: KW mu chikwi Watts (1 kW = 1000 W). zitsanzo zina yosanthula mphamvu magetsi kujambula. Nazi zitsanzo zingapo za mmene kumasulira mfundo anasonyeza:

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

Nthawi zina chofunika mphamvu wagawo, m'kukoma Watts asanduke kilowatts. Tikukumbukira Watts angati pa kilowatt chake kudziwika mtengo akufufuta chikwi. Mwina koma nayo manambala atatu lamanzere.

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

Tiyeni tione chinthu monga "kilowatt maola"

Mu maola kilowatt (kapena maola Watt) chimaonekera ndi magetsi mowa mphamvu paola unit. Mwachitsanzo, kutenga kompyuta ochiritsira ndi mphamvu ya 0,65 kW. Tiyeni tinene kuti ntchito kwa ola limodzi. Kodi ndikudziwa kuchuluka kwa mphamvu iye anachita nthawi imeneyi? Kwambiri ophweka: 0,65 kW kuchulukitsa ndi ola 1, 0,65 kWh. Mwachizolowezi stovattnaya babu, ola limodzi zimawononga 100 Watts mphamvu Choncho, pa tsiku la ntchito yothandizira kuti tikatha 2.4 kW. Ndi angati Watts kW, Takambirana kale pamwambapa.

Kuweta banja ogula magetsi

Pakali pano, ngakhale anthu olemera Anayamba kuganiza za ndalama mphamvu - akana incandescent mababu ndi kutibwezera ndi mababu ndalama kuwala kapena kuwala emitting diode. Pamene inu kusankha kwanu chipangizo chamagetsi chizindikiro chachikulu, chimene makamaka lozani zipangizo zochita dzuwa. mungapeze zida amenewa mu nyumba iliyonse kapena nyumba, firiji, TV, kompyuta, chitsulo, magetsi ketulo. Taganizirani mowa mphamvu otchulidwa mayunitsi. Firiji ambiri ukugwira ntchito usana ndi usiku, mowa mphamvu yake mlingo ranges kuchokera 0,7 kuti 1.3 kW patsiku - izo kudzadalira kukula kwa chipangizo ndi yozungulira kutentha. Kompyuta, malinga zilibe zimitsani kwa tsiku akhoza amathera 13.5 kW. TV chomwecho pafupifupi kumwa 2.5 kW kwa maola 24. Komabe, lalikulu "spenders" ndi zipangizo Kutentha: maketulo magetsi, heaters madzi, cookers magetsi ndi ena. Mwachitsanzo, ketulo magetsi kwa mphindi 20-25 amadya 1-1.2 kW, amene angayerekezedwe ndi firiji mosalekeza ntchito. Ndipo kuchuluka kwa mphamvu inu amaika?
