Tiri watts inta per kw

Haddii aad xiisaynayso in su'aasha ah ee watts inta per kw, jawaabta waxaad ka heli doontaa, ka dib markii reading this article. Waa maxay Watt? Tani cabbirka awood unit ay qaateen nidaamka International qiyaaseed ee units (SI). Waxa ay magaca sabab u-hindisa makaanik ka soo jeeda brass-Irish helay James Watt, yaa abuuray engine a uumi universal. Ilaa 1882 markii ugu of degsiimooyinka ee hooras loo adeegsaday sida qaybta aasaasiga ah ee cabbirka, iyo kaliya ka dib markii farsamo been abuurtay meel kasta (gaar ahaan injineernimada korontada) ansixiyay unit cusub oo awood - watts. In physics, awood waa isticmaalka tamarta ee geedi socodka halkii unit waqtiga, siday u kala horreeyaan, wuxuu noqon doonaa siman yihiin in ay ka mid watt mid joule per labaad (W = J / s).

Imisa watts ee kilowatts

Dadka si joogto wajahay fikradda guud ee awoodda korontada ee guriga. All qalabka in baasaboorka ayaa lagu wadaa in isticmaalka xoogga. Xataa at hoose nalka incandescent, in sibraar galaas qoran .. 40 W, 60 W, 100 W, iwm Sida ee microwave ama mashiinka dharka lagu dhaqo oo ah, qiimaha waxaa loo arkaa inay aad uga badan: 500-1000 W iyo 2-2, 5 kw, siday u kala horreeyaan. Sida qiyamka kale jirka, horgale "kilo" ah macnaheedu waa kun oo xero. Taasi waa, qiimaha tirsi awoodda qiyaasay in kilowatts, tarma by 1000 ama ka guurto hal dhibic ka tobanle inay calaamad sax ah saddex lambar: si aan u hesho qiimaha korontada ee watts.

Sayidka, su'aasha ah ee sida badan watts kilowatts, waxaan ka helnay jawaab cad: kw in mid ka mid kun oo watts (1 kw = 1000 W). tusaalooyin dheeraad ah falanqaynta xoog wax lagu qoro korontada. Halkan waxaa ku qoran dhowr tusaale oo ku saabsan sida loo turjumo qiyamka tilmaamay:

• 2.5 kw = 2500 watts.
• 0.2 kw = 200 watts.
• 3.095 kw = 3095 watts.

Mararka qaarkood qaybta xoogga loo baahan yahay, ayaa muujiyay in watts, diinta kilowatts. Annagu waxaannu xusuusan nahay watts inta per qiimaha kilowatt sidaas daraaddeed yaqaan qaybiyey kun. Ama comma a qaadan karo si loo saddex lambar bidixda.

• 2750 W = 2.7 kw.
• 70 W = 0.07 kw.
• 150 W = 0.15 kw.

Ha waxaas oo kale ka fikiro si aynu sida "kilo-waat saacaddii"

In saacadood kilowatt (ama saacadood watt) waxaa lagu cabbiraa isticmaalka korontada saacaddii unit. Tusaale ahaan, u qaataan computer a caadiga ah oo leh awooda ka mid ah 0,65 kw. Ina keena aynu ka fikirno in uu shaqeeyeen saacad keliya. Sidee baan ku ogaan inta ay le'eg tamarta uu bixisay inta lagu jiro xilliga this? Mid aad u fudud: 0,65 kw dhufto 1 saac, 0,65 kWh. stovattnaya caadiga ah guluubka, hal saac baabbi'in 100 watts awoodda, sidaas darteed, maalintii hawlgalka joogto Bixin doonaan 2.4 kw. Imisa watts kw, aynu hore u wada hadleen kor ku xusan.

asaasiga ah macaamiisha korontada

Waqtigan xaadirka ah, xataa dadka hodanka ah ayaa bilaabay in ay ka fekeraan kaydka tamarta - ayay u diidaan inay incandescent nalalka iyo ku baddallo kuwa nalalka dhaqaale ama diode light-emitting. Marka aad dooran dhimaya ah qalabka guriga ugu weyn, kaas oo si gaar ah farta qalabka falalka hufnaan. waxaad ka heli kartaa qalabka sida ee guriga kasta ama guri dabaq, qaboojiyaha, telefishanka, computer, birta, kidhligii korontada. Ka fiirso isticmaalka awoodda unugyada ku xusan. Qaboojiyaha caadiga ah ka shaqeeya saacad, safafka heerka isticmaalka tamarta ay ka 0.7 1.3 kw ah maalin kasta - waxaa ku xirnaan doontaa xajmiga qalabka iyo heerkulka daarmayaay'e. Computer, ay shardi tahay in uusan dami maalin qaataan kartaa ilaa 13.5 kw. TV isticmaalka celcelis ahaan la mid ah 2.5 kw 24 saacadood. Si kastaba ha ahaatee, "ayuu lacago" ugu weyn yihiin qalabka kululaynta: dharyo sugan korontada, kululeeyayaasha biyaha, makiinadaha korontada iyo kuwa kale. Tusaale ahaan, kidhligii koronto ah 20-25 daqiiqo gubtay 1-1.2 kw, kaas oo la la qaboojiyaha si joogto ah shaqada marka la barbar dhigo karo. Iyo inta tamar aad arsaaqa?
