Indwangu ephefumulayo engangeni manzi

Imisebenzi eyinhloko yendwangu ephefumulayo engangeni manzi yilena: ukungangeni kwamanzi, umswakama okwazi ukungena ngaphakathi, ukuphefumula, ukuvikela ukushisa, ukuvikela umoya nokufudumala.Mayelana nobuchwepheshe bokukhiqiza, izidingo zobuchwepheshe zendwangu ephefumulayo engenamanzi ziphakeme kakhulu kunendwangu evamile engangeni manzi.Ngesikhathi esifanayo, kusukela ekubukeni kwekhwalithi, izindwangu eziphefumulayo ezingenawo amanzi nazo zinezinye izindwangu ezingenamanzi azikho izici zokusebenza.Indwangu ephefumulayo engangeni manzi ayigcini nje ngokuthuthukisa ukuqina komoya kanye nokucinana kwamanzi kwendwangu, kodwa futhi inomoya wayo oyingqayizivele wokuphefumula, ongenza umhwamuko wamanzi esakhiweni ukhishwe ngokushesha, ugweme isikhunta esakhiweni, futhi ugcine umzimba womuntu womile. ngaso sonke isikhathi.Ixazulula ngokuphelele izinkinga zokungena komoya, ukuvimbela umoya, ukungangeni kwamanzi, nokugcinwa kokushisa, njll, futhi iwuhlobo olusha lwendwangu enempilo neyokuvikela imvelo.
Esimeni somhwamuko wamanzi, izinhlayiya zamanzi zincane kakhulu.Ngokusho kwesimiso sokuhamba kwe-capillary, bangangena ku-capillary ngakolunye uhlangothi ngokushelela, futhi ngaleyo ndlela babe nokungena kwe-steam.Lapho umhwamuko uhlangana ube amaconsi amanzi, izinhlayiya ziba zinkulu.Ngenxa yomphumela wokungezwani okungaphezulu kwamaconsi amanzi (ama-molecule amanzi “adonsana”), ama-molecule amanzi awakwazi ukuphunyuka kumaconsi amanzi ukuze angene kolunye uhlangothi ngokushelela, okuwukuvimbela ukungena kwamanzi futhi enze ifilimu evumela amanzi ukuba ingangeni manzi.
Izindwangu zangempela ezingangeni manzi zingamelana nokucindezela kwamanzi futhi zingangeni esimweni sezulu esiswakeme isikhathi eside.Isibonelo, uma uhamba emvuleni isikhathi eside, uguqa noma uhlale emhlabathini omanzi, ngeke kube khona ukugeleza kwamanzi.
Umngane oxhumana naye ngaphandle isikhathi esithile uyazi, ubuchwepheshe obuphezulu ukuthi izingubo zangaphandle zibukisayo, ukusebenza okuphezulu kuhlobene kakhulu nezindwangu eziphefumulayo ezingangeni manzi, ngakho-ke izindwangu eziphefumulayo ezingenawo amanzi emva kwakho konke ukuthi isimiso, zonke izinhlobo zezinto zokwakha emakethe kanjani ngemva kwakho konke umphumela?
Ukungangeni kwamanzi, okuphefumulayo, umsindo ngokwawo uwumzimba ophikisanayo, njengoba ungangeni manzi, uvalwe kanjalo, sonke siyazi, amanzi awangeni kuwo wonke umuntu, ngakho-ke kungenzeka kanjani ukuphefumula?Empeleni lokhu kanye nezici zamanzi, njengoba wonke umuntu azi, ubuso bamanzi bunokungezwani, butholakala empilweni yakho, lapho sithela amaconsi amanzi aphakeme kancane kunalawo avame ukuthi awagelezi, lokhu kuwumphumela ukungezwani kwamanzi ebusweni, lesi senzakalo ngokuyinhloko sibangelwa i-molecule yamanzi inokukhanga okukhulu kwamangqamuzana, kuphela yenza i-molecule yamanzi ngayinye ibe eduze ngangokunokwenzeka futhi ingahlukani, futhi umhwamuko wamanzi nawo ungama-molecule wamanzi, kodwa ngalesi sikhathi phakathi kwe-molecule ngayinye izimele ngokuphelele, ukuze lingakwazi ukuxhunyaniswa eduze kangaka.Ukusebenzisa lesi sakhiwo, ukuhlolwa kwaselabhorethri kuye kwathola ukuthi uma imbobo incane ngokwanele, ingadlula amanzi kuphela esimweni somhwamuko, hhayi amanzi awuketshezi.Ukusebenzisa lesi sici ukuze kusungulwe izinto eziphefumulayo ezingangeni manzi, ukusetshenziswa kwe-polyester fiber impahla enyakazayo ifomu imbobo emincane eminingi endwangwini, enento evamile engangeni manzi ephefumulayo i-GORE - TEX, isibonelo, umgomo wezinto ezibonakalayo awukona i-intshi yesikwele phezulu. emakhulwini ezigidi ezincane ezihlakazekile, ububanzi bembobo ngayinye bungaphezu kwezinkulungwane ezingamashumi amabili zamaconsi amancane oketshezi, kodwa izikhathi ezingu-700 zikhulu kunesimo esincane somhwamuko wamanzi, lesi isimiso sokungangeni kwamanzi nokuphefumula.
