Umehluko Phakathi Komusi Oshisayo Nesiphepho Esigcwele

Umusi ungumthombo wokushisa odingwa yizo zonke izitshalo zokuhlanza izingubo. Pho-ke, yimuphi umehluko phakathi komusi oshisayo kakhulu nomusi ogcwele? Umehluko usesimeni sawo se-thermodynamic.

I-Steam Egcwele

Umusi ogcwele usho isimo lapho kokubili uketshezi negesi kuhlangana ndawonye ngokulinganayo ngengcindezi ethile. Kulesi simo, uketshezi luzoqhubeka nokuhwamuka kuyilapho igesi izoqhubeka nokujiya kuze kube yilapho kokubili kufinyelela equilibrium enamandla. Ngaleso sikhathi, izinga lokushisa kanye nengcindezi yeumusiZiqinile. Zibizwa ngokuthi izinga lokushisa eligcwele kanye nengcindezi egcwele. Ekuqaleni kokulingana, umusi uyisitimu esimanzi esigcwele. Uma abantu beqhubeka nokushisa, umusi uzoba umusi ogcwele owomile ngemva kokuba wonke amanzi emanzini agcwele epheshuliwe. Izinga lokushisa lomusi kusukela emanzini agcwele kuya emanzini agcwele lihlala lifana. Izinga lokushisa lomusi alikhuphuki phakathi nenqubo kusukela ekugcwaleni okumanzi kuya ekugcwaleni okomile. Ekucindezelweni okuqinile, uma umusi ogcwele owomile ushiswa kakhulu, izinga lokushisa lawo liyakhuphuka bese uba umusi oshisayo kakhulu. Umusi oshisayo kakhulu awunawo amaconsi amanzi noma inkungu yoketshezi futhi uyigesi yangempela.

❑ Isibonelo

Ukukubeka esimweni esilula:

● Ngengcindezi ethile, amanzi aqala ukuhwamuka bese kancane kancane aba umusi ngemva kokushiswa aze abile. Ngalesi sikhathi, izinga lokushisa lomusi lilingana nezinga lokushisa lokugcwala. Leli zinga lokushisa lihlobene nengcindezi. Uma ingcindezi iphakeme, izinga lokushisa lokugcwala liphakeme. Ngokuphambene nalokho, uma ingcindezi iphansi, izinga lokushisa lokugcwala liphansi. Uma ingcindezi ingu-0.10MPa, izinga lokushisa lokugcwala lingama-99.09°C. Uma ingcindezi ingu-4.05 MPa, izinga lokushisa lokugcwala lingama-249.18°C. Uma ingcindezi ingu-10.13 MPa, izinga lokushisa layo lokugcwala lingama-309.53°C.

Umusi Oshisayo Kakhulu

Izinga lokushisa lizoqhubeka likhuphuka futhi lidlule izinga lokushisa lokugcwala kule ngcindezi ngemva kokuba umusi ogcwele usushiswe kakhulu. Lo musi, odlula izinga lokushisa lokugcwala, ubizwa ngokuthi umusi oshisiwe kakhulu. Kulesi simo, izinga lokushisa kanye nengcindezi yomsi akusazinzile. Lapho ukushisa kukhuphuka, kuyakhula futhi. Umusi oshisiwe kakhulu unamandla okushisa aphezulu kanye namandla okushisa aphezulu.

❑ Inkinga

Kodwa-ke, ekusetshenzisweni kwangempela, ukusebenzisa umusi oshisayo kakhulu ekushiseni akuphumelelanga kahle. Lokhu kungenxa yokuthi umusi oshisayo kakhulu kumele upholiswe ekushiseni okugcwele ukuze kukhishwe i-enthalpy yokuhwamuka. Ukushisa okukhishwe ekupholiseni umusi oshisayo kakhulu kuya ekushiseni okugcwele kuncane kakhulu uma kuqhathaniswa ne-enthalpy yokuhwamuka.

● Uma ukushisa okukhulu komusi kuncane kakhulu, le ngxenye encane yokushisa kulula ukuyikhipha. Kodwa-ke, uma ukushisa okukhulu kuphezulu kakhulu, isikhathi sokupholisa siba side kakhulu. Phakathi nalesi sikhathi, kungakhishwa ukushisa okuncane kakhulu.

Emishinini yokushintshanisa ukushisa yangempela, ukusetshenziswa komusi oshisayo kakhulu kuzokwakha udonga olomile ngaphakathi kwemishini yokushintshanisa ukushisa. Le ndawo izokwakha ngokushesha isikali, okubangela ukuthi udonga lwamapayipi lushise ngokweqile futhi kuholele ekuhlulekeni kwepayipi. Ngakho-ke, yize izinga lokushisa lomusi oshisayo kakhulu ngengcindezi efanayo liphakeme kunelomusi ogcwele, amandla alo okushisa aphansi kunelomusi ogcwele.

Isiphetho

Ekukhiqizeni kwangempela, uma izimboni zokuhlanza izingubo zifuna ukusebenzisa umusi oshisayo kakhulu noshisayo kakhulu okhiqizwa yisitshalo samandla, umusi kumele uqale udlule ohlelweni lwesiteshi sokususa ukushisa nokunciphisa umfutho ukuze uguqule umusi oshisayo kakhulu ube umusi ogcwele ngaphambi kokuba usetshenziswe. Umusi oshisayo kakhulu ungakhipha ukushisa kwawo okucashile okuwusizo kakhulu kuphela uma upholisiwe uye esimweni esigcwele.
