Kusiyana Pakati pa Steam Yotentha Kwambiri ndi Steam Yokhuta

Nthunzi ndi gwero la kutentha lomwe chomera chilichonse chotsukira zovala chimafunikira. Ndiye, kodi kusiyana pakati pa nthunzi yotentha kwambiri ndi nthunzi yokhuta ndi kotani? Kusiyanaku kuli mu mkhalidwe wawo wa thermodynamic.

Nthunzi Yokhuta

Nthunzi yokhuta imatanthauza mkhalidwe umene madzi ndi mpweya zonse zimakhala zofanana pa mphamvu inayake. Pachifukwa ichi, madziwo adzapitiriza kuuluka pomwe mpweyawo udzapitiriza kuuma mpaka ziwirizo zitafika pa mphamvu imodzi. Panthawiyo, kutentha ndi mphamvu yanthunziZimakhazikika. Zimatchedwa kutentha kokhuta ndi kupanikizika kokhuta. Poyamba pa mgwirizano, nthunzi ndi nthunzi yonyowa yokhuta. Ngati anthu apitiliza kutentha, nthunziyo idzakhala nthunzi youma yokhuta madzi onse m'madzi okhuta atasungunuka. Kutentha kwa nthunzi kuchokera ku kukhuta konyowa kupita ku kukhuta kouma kumakhalabe komweko. Kutentha kwa nthunzi sikukwera panthawiyi kuyambira kukhuta konyowa kupita ku kukhuta kouma. Pa kupanikizika kokhazikika, ngati nthunzi youma yokhuta ikatenthedwa kwambiri, kutentha kwake kumakwera ndipo kumakhala nthunzi yotentha kwambiri. Nthunzi yotentha kwambiri ilibe madontho amadzimadzi kapena nthunzi yamadzimadzi ndipo ndi mpweya weniweni.

❑ Chitsanzo

Kuti timvetse bwino nkhaniyi:

● Pakapanikizika kwina, madzi amayamba kuphwanyika ndipo pang'onopang'ono amakhala nthunzi atatenthedwa mpaka kuwira. Panthawiyi, kutentha kwa nthunzi kumakhala kofanana ndi kutentha kwa saturation. Kutentha kumeneku kumagwirizana ndi kuthamanga. Kupanikizika kukakhala kwakukulu, kutentha kwa saturation kumakhala kwakukulu. Mosiyana ndi zimenezi, kuthamanga kukakhala kochepa, kutentha kwa saturation kumakhala kochepa. Kupanikizika kukakhala 0.10MPa, kutentha kwa saturation kumakhala 99.09°C. Kupanikizika kukakhala 4.05 MPa, kutentha kwa saturation kumakhala 249.18°C. Kupanikizika kukakhala 10.13 MPa, kutentha kwake kwa saturation kumakhala 309.53°C.

Mpweya Wotentha Kwambiri

Kutentha kudzapitirira kukwera ndikupitirira kutentha kwa saturation pa kuthamanga kumeneku nthunzi yokhuta itatenthedwa kwambiri. Nthunzi iyi, yomwe imapitirira kutentha kwa saturation, imatchedwa nthunzi yotentha kwambiri. Pachifukwa ichi, kutentha ndi kuthamanga kwa nthunzi sizimakhazikikanso. Kutentha kukawonjezeka, zimawonjezekanso. Nthunzi yotentha kwambiri imakhala ndi mphamvu yotentha kwambiri komanso mphamvu yotentha kwambiri.

❑ Zovuta

Komabe, pakugwiritsa ntchito kwenikweni, kugwiritsa ntchito nthunzi yotentha kwambiri potenthetsa sikuthandiza kwenikweni. Izi zili choncho chifukwa nthunzi yotentha kwambiri iyenera kuziziritsidwa kufika kutentha kokwanira kuti itulutse enthalpy ya evaporation. Kutentha komwe kumatulutsidwa kuchokera ku kuzizira kwa nthunzi yotentha kwambiri kufika kutentha kokwanira ndi kochepa kwambiri poyerekeza ndi enthalpy ya evaporation.

● Ngati kutentha kwakukulu kwa nthunzi kuli kochepa kwambiri, gawo laling'ono la kutenthali limakhala losavuta kutulutsa. Komabe, kutentha kwakukulu kukakhala kwakukulu kwambiri, nthawi yozizira imakhala yayitali kwambiri. Munthawi imeneyi, kutentha kochepa kwambiri kokha ndiko komwe kungatulutsidwe.

Mu zipangizo zenizeni zosinthira kutentha, kugwiritsa ntchito nthunzi yotentha kwambiri kudzapanga khoma louma mkati mwa zipangizo zosinthira kutentha. Malo amenewa adzapanga kukula msanga, zomwe zimapangitsa kuti khoma la chitoliro litenthe kwambiri ndipo zimapangitsa kuti chitoliro chilephere kugwira ntchito. Chifukwa chake, ngakhale kutentha kwa nthunzi yotentha kwambiri pamlingo womwewo kuli kokwera kuposa kwa nthunzi yodzaza, mphamvu yake yotenthetsera ndi yotsika kuposa ya nthunzi yodzaza.

Mapeto

Pakupanga kwenikweni, ngati mafakitale ochapira zovala akufuna kugwiritsa ntchito nthunzi yotentha kwambiri komanso yotentha kwambiri yopangidwa ndi fakitale yamagetsi, nthunziyo iyenera choyamba kudutsa mu dongosolo la siteshoni yochotsera kutentha kwambiri komanso yochepetsa kupanikizika kuti isinthe nthunzi yotentha kwambiri kukhala nthunzi yodzaza isanagwiritsidwe ntchito. Nthunzi yotentha kwambiri imatha kutulutsa kutentha kwake kobisika kokha ikazizira mpaka kudzaza.
