Mphamvu yamafuta

Mphamvu yamafuta imagwiritsa ntchito kangapo

M'nkhani zam'mbuyomu takhala tikuwona zomwe Mphamvu zamagetsi ndi mphamvu zamagetsi. Munkhani izi tidatchulapo mphamvu yotentha ngati gawo la mphamvu yomwe imakhudza ndikukhala ndi thupi lomwe likufunsidwa. Mphamvu yamafuta Ndi mphamvu yomwe tinthu tonse tomwe timapanga thupi timakhala nayo. Kutentha kukatentha pakati pakukula ndi kuchepa, ntchito ya thupi imakula. Mphamvu zamkatizi zimawonjezeka kutentha kumakulira ndikucheperachepera.

Tsopano tiunikiranso za mtundu uwu wamagetsi ndikumaliza kudziwa kwathu zamagetsi osiyanasiyana omwe alipo. Kodi mukufuna kuphunzira zambiri za izi? Pitirizani kuwerenga ndipo mudzapeza.

Makhalidwe a mphamvu yamatenthedwe

Mphamvu yamafuta ndiyomwe imapereka kutentha

Ndi mphamvu yomwe imasokoneza zochitika zosiyanasiyana za calorific zomwe zimachitika matupi a kutentha kosiyanasiyana akakhudzana. Malingana ngati matupiwo amakhalabe ndi mkangano pakati pawo, mphamvuzi zimafalikira kuchokera ku thupi lina kupita ku linzake. Izi ndi zomwe zimachitika, mwachitsanzo, tikayika dzanja lathu pamtunda. Patapita kanthawi, pamwamba padzakhala kutentha kwa dzanja, chifukwa adampatsa.

Kupeza kapena kutaya mphamvu zamkati panthawiyi amatchedwa kutentha. Mphamvu yamafuta imapezeka m'njira zosiyanasiyana. Chifukwa chake, thupi lililonse lomwe lili ndi kutentha kwina limakhala ndi mphamvu zamkati mkati.

Zitsanzo za mphamvu yamafuta

Tiyeni tiwone bwino magwero opezera mphamvu zamafuta:

  • Chilengedwe ndi Dzuwa Ndizigawo ziwiri zamagetsi zomwe zimapatsa mphamvu matupi. Mwachitsanzo, chitsulo chikakhala padzuwa mosalekeza, kutentha kwake kumakwera chifukwa chimalowetsa mkati. Kuphatikiza apo, nyenyezi yamfumu ndiye chitsanzo chomveka cha mphamvu zamafuta. Ndilo gwero lalikulu kwambiri lodziwika bwino lamphamvu yamafuta. Nyama zomwe sizingathe kutentha kutentha zimagwiritsa ntchito gwero la mphamvuzi kutero.
  • Wiritsani madzi: Pamene kutentha kwa madzi kumawonjezeka, mphamvu yotentha yamtundu wonse imayamba kuchulukana. Nthawi inafika pamene kuwonjezeka kwa kutentha kwa mphamvu yotentha kumapangitsa madzi kusintha pang'ono.
  • Malo amoto mphamvu zopangidwa mu chimneys zimachokera kukuwonjezeka kwa mphamvu yamafuta. Apa pali kuyatsa kwazinthu zofunikira kuti nyumba izitha kutentha.
  • Chotenthetsera: imagwiritsa ntchito kukulitsa kutentha kwa madzi munjira yofananira ndi nthawi yomwe tikutentha.
  • Zochitika modabwitsa zomwe zimachitika potentha mafuta.
  • Zochita za nyukiliya zomwe zimachitika mwa kutulutsa nyukiliya. Zimapezekanso zikachitika ndikusakanikirana kwamkati. Ma atomu awiri akakhala ndi chofanana chofananira amalumikizana kuti akhale ndi phata lolemera ndipo panthawiyi amatulutsa mphamvu zambiri.
  • Zotsatira zake zimachitika pamene kondakitala azungulira mphamvu yamagetsi ndipo mphamvu zamagetsi zomwe ma elekitironi ali nazo zimasandulika kukhala mphamvu zamkati chifukwa cha kugundana kosalekeza.
  • Mikangano Zimapanganso mphamvu zamkati, popeza palinso kusinthana kwa mphamvu pakati pa matupi awiri, kaya ndi thupi kapena mankhwala.

Kodi mphamvu zamafuta zimapangidwa bwanji?

Tiyenera kuganiza kuti mphamvu siyilengedwa kapena kuwonongedwa, koma imangosinthidwa. Mphamvu yamafuta imapangidwa m'njira zambiri. Amapangidwa ndi mayendedwe a ma atomu ndi mamolekyulu azinthu ngati mawonekedwe amagetsi amakono omwe amapangidwa ndimayendedwe osasintha. Dongosolo likakhala ndi mphamvu yochulukirapo yamphamvu, maatomu ake amayenda mwachangu.

Kodi mphamvu yamafuta imagwiritsidwa ntchito bwanji?

Mphamvu yamafuta imatha kusinthidwa ndi injini yotentha kapena makina. Zina mwazitsanzo zofala kwambiri ndi injini yagalimoto, ndege kapena bwato. Mphamvu yamafuta imatha kugwiritsidwa ntchito m'njira zambiri. Tiyeni tiwone omwe ali akulu:

  • M'malo omwe kutentha kumafunika. Mwachitsanzo, monga kutentha m'nyumba.
  • Kutembenuka kwa mphamvu yamakina. Chitsanzo cha izi ndi makina oyaka magalimoto.
  • Kusintha kwa mphamvu zamagetsi. Izi zimapangidwa muzomera zamagetsi.

Kuyeza kwa mphamvu zamkati

Mphamvu zamkati zimayezedwa molingana ndi Njira Zamayiko Zamtundu ku Joules (J). Ikhoza kuwonetsedwanso mu calories (Cal) kapena kilocalories (Kcal). Kuti timvetsetse mphamvu zamkati bwino, tiyenera kukumbukira mfundo yosungira mphamvu. "Mphamvu sizimapangidwa kapena kuwonongedwa, zimangosintha kuchokera kumzake kupita kwina." Izi zikutanthauza kuti ngakhale mphamvu ikupitilizabe kusintha, nthawi zonse imakhala yofanana.

Mphamvu yamagetsi yomwe galimoto imanyamula ikagunda nyumba imapita molunjika kukhoma. Chifukwa chake, zotsatira zake, mphamvu zake zamkati zimawonjezeka ndipo galimoto imachepetsa mphamvu zake.

Zitsanzo za mphamvu yamafuta

Kutentha kapena mphamvu yotentha ndi mwachitsanzo mu:

  • Nyama zamagazi ofunda. Mwachitsanzo, tikamva kuzizira timakumbatira ena. Pang'ono ndi pang'ono timamva bwino, chifukwa amatitumizira kutentha kwake.
  • Pazitsulo zomwe zimawonekera padzuwa. M'chilimwe, makamaka, chimayaka.
  • Tikaika ice ice mu kapu yamadzi otentha timawona kuti imasungunuka chifukwa kutentha kumayendetsedwa kwa iyo.
  • Masitovu, ma radiator, ndi ina iliyonse Kutentha.

Kusokonezeka pafupipafupi

Mphamvu yamafuta imasamutsidwa ndi njira zosiyanasiyana

Ndizofala kwambiri kusokoneza kutentha kwa mphamvu ndi mphamvu yotentha. Nthawi zambiri amagwiritsidwa ntchito ngati mawu ofanana ngakhale alibe chochita nawo. Kutentha kwamphamvu kumangotengera kutentha komwe kumachitika muzochitika zake zopatsa mphamvu. Chifukwa chake, amasiyanitsidwa ndi mphamvu yamafuta yomwe ndikutentha kokha.

Kuchuluka kwa kutentha m'thupi ndiyeso yamphamvu yamafuta, pomwe kutentha komwe kumatha kutuluka mthupi kumawonetsa kuti ili ndi mphamvu yayikulu yamphamvu yamafuta. Kutentha kwa thupi kumatipatsa chidwi chakutentha ndipo kumatha kutipatsa chizindikiro chosonyeza kuchuluka kwa mphamvu zomwe zili nazo. Monga tanenera kale, kutentha kwa thupi kumakhala ndi mphamvu zambiri.

Kutentha kumafalikira m'njira zosiyanasiyana. Tiyeni tiwunikenso chimodzi ndi chimodzi:

  • Mphamvu yamagetsi yamagetsi yamagetsi.
  • Kuyendetsa. Mphamvu zikamatumizidwa kuchokera ku thupi lotentha kupita ku thupi lozizira, zimachitika. Ngati matupi ali ndi kutentha komweko, palibe kusinthana kwa magetsi. Mfundo yakuti matupi awiriwa amafanana ndi kutentha kwawo akamagwirizana ndi mfundo ina ya fizikiki yotchedwa kufanana kwamatenthedwe. Mwachitsanzo, tikakhudza chinthu chozizira ndi dzanja, mphamvu yamatenthedwayo imatumizidwa ku chinthu chomwe chimapangitsa kumva kuzizira m'manja mwathu.
  • Kulumikizana. Izi zimachitika mamolekyulu otentha kwambiri amasinthidwa kuchokera mbali imodzi kupita mbali ina. Zimachitika mwachilengedwe mosalekeza mu mphepo. Mitengo yotentha kwambiri imakonda kusunthira komwe kuli kachulukidwe kochepa.

Mphamvu zina zokhudzana nazo

Mphamvu yamafuta imagwirizana ndi mitundu ina yambiri yamagetsi. Apa tili ndi ena a iwo.

Kutentha kwa dzuwa mphamvu

Mphamvu yamafuta imagwiritsa ntchito mosiyanasiyana

Ndi mtundu wa mphamvu zowonjezereka zomwe zimakhala ndi Kusintha kwa mphamvu ya dzuwa kukhala kutentha. Mphamvu imeneyi imagwiritsidwa ntchito kutenthetsa madzi pamagwiritsidwe osiyanasiyana monga apakhomo kapena mzipatala. Zimatenthetsanso masiku amasiku a dzinja. Gwero ndi dzuwa ndipo limalandiridwa molunjika.

Mphamvu yotentha ndi mpweya

Kupeza mphamvu yamafuta kumakhudza chilengedwe chifukwa cha potulutsa mpweya woipa ndi zinyalala za nyukiliya. Komabe, ngati mphamvu yochokera mkatikati mwa dziko lapansi ikugwiritsidwa ntchito. Ndi mtundu wa mphamvu zowonjezeranso zomwe sizimaipitsa kapena kuwononga chilengedwe.

Mphamvu zamagetsi zamagetsi ndi zamagetsi

Mphamvu yamafuta imatha kusandulika kukhala mphamvu yamagetsi. Mwachitsanzo, mafuta ndi malasha amapanga magetsi poiwotcha ndikutulutsa. Mphamvu zamagetsi zimaperekedwa chifukwa chakutha kusiyana pakati pa mfundo ziwiri ndipo amalola kuti pakhale magetsi pakati pa awiriwo akakumana ndi woyendetsa magetsi. Kondakitala akhoza kukhala chitsulo.

Kutentha kwamphamvu ndi mtundu wa mphamvu yotulutsidwa ngati kutentha chifukwa chokhudzana ndi thupi lomwe lili ndi kutentha kwambiri kwa wina wokhala ndi kutentha pang'ono, komanso kumatha kupezeka mosiyanasiyana kapena njira zosiyanasiyana monga tanenera kale. Mphamvu zamagetsi ndiye amene ali ndi mgwirizano wamankhwalandiko kuti, ndi mphamvu yopangidwa kokha ndi kusintha kwa mankhwala.

Ndi izi mudzatha kudziwa bwino mphamvu zamafuta.
