Okokuqala, sidinga ukuqonda inqubo eyisisekelo ye-coffee latte art. Ukuze udwebe inkomishi ephelele ye-coffee latte art, udinga ukuqonda izici ezimbili ezibalulekile: ubuhle be-emulsion nokuhlukaniswa.
Ubuhle be-emulsion bubhekisela kugwebu olubushelelezi, olucebile lobisi, kanti ukuhlukana kubhekisela esimweni esinqunyiwe sobisi nekhofi. Inhlanganisela yalezi zici ezimbili ingakha ubuciko be-coffee latte obumangalisayo. Ngakho, kungani ubisi lwakha igwebu? Lokhu kuhilela izimiso zokungezwani kwendawo kanye nokwakheka kwebhamuza ku-physics
Amafutha kanye namaprotheni obisi yizithako eziyinhloko ekwenzeni igwebu. Uma ubisi lufudunyezwa, amafutha ayancibilika futhi amaprotheni ashintshe. Ngale ndlela, abantu abajwayelene nemigomo ye-foam bazokwazi ukuthi ukwakheka kwegwebu akunakuhlukaniswa nokucindezeleka okungaphezulu. Ukungezwani kwendawo kuwumphumela wokusebenzelana phakathi kwama-molecule awuketshezi futhi kuyisici esibangela ukuthi uketshezi olungaphezulu luthambekele ekunciphiseni amandla. Ama-molecule wamafutha namaprotheni obisi aqoqana phezu koketshezi, enze isakhiwo esifana nefilimu encane. Kulolu lwelwesi oluncane, umoya uvaleleke ngaphakathi, wenze amagwebu amancane. Uma ubisi lufudunyezwa, lawa mabhamuza ayanda futhi agcine umumo othile nokuzinza.
Okulandelayo, ake sibheke ukuhlukana kobisi. Uma ubisi luxubene nekhofi, ubisi nekhofi kuzohlukana ngenxa yomehluko wokuminyana kanye ne-viscosity. Phakathi nale nqubo, amaphethini ahlukahlukene amahle angakhiwa enkomishini ngokusebenzisa imisebenzi ehlakaniphile. Eqinisweni, kunezimiso zomzimba ngemuva kwalesi simo sokubeka izingqimba. Ukwehlukana phakathi kobisi nekhofi kubangelwa umehluko wokuminyana. Ubisi luminyene kunekhofi, ngakho luzocwila ngenkathi ikhofi lintanta phezulu. Ukuze wenze amaphethini ahlukene, ubisi ludinga ukuthululwa enkomishini ezindaweni ezahlukene ukuze kuzuzwe umphumela oyifunayo.
Ngaphezu kobudlelwano phakathi kwegwebu nokuhlukana, kunomunye umqondo obalulekile wefiziksi okufanele ukhulunywe, futhi leyo inombolo kaReynolds. Inombolo ye-Reynolds inombolo engenasici esetshenziselwa ukuchaza ukugeleza koketshezi ngesivinini esihlukile nokuminyana. Ku-coffee latte art, ngokushintsha isivinini kanye ne-angle yokuthulula ubisi, ukuhlukaniswa kobisi nekhofi kungathinteka. Lapho isivinini sishesha, uketshezi luhlukaniswa ngokuphelele, futhi lapho ijubane lihamba kancane, imigqa emihle enephethini ecacile kakhulu iyakhiwa.
I-coffee latte art ihlanganisa ukwakheka kwegwebu nokuhlukaniswa kobisi nekhofi ngokusebenzisa izimiso zomzimba. Ngokusebenza okuhle, amaphethini ahlukahlukene amahle angakhiwa ebusweni bekhofi, anikeze abantu injabulo ebonakalayo. Ngokuqonda izimiso, singakwazi ukuqonda kangcono futhi siqonde ubuciko be-coffee latte art, futhi sizame ukudala imisebenzi emangalisayo kakhulu lapho sisebenza ngezandla zethu. Nakuba lesi sihloko sichaza kafushane izimiso ze-coffee latte art, sithemba ukuthi abafundi bangaqonda lobu buciko ngokombono we-physics. I-coffee latte art iyindlela eyingqayizivele ehlanganisa izimiso zesayensi nobuchule bobuciko, okusilethela injabulo enhle. Kungakhathaliseki ukuthi sizenzela owethu noma sinambitha umsebenzi wabanye abantu, singaba nolwazi olujulile lokuthakazelisa kwekhofi.
