Fluid Dynamics
Ku-physics nobunjiniyela, i-fluid dynamics iyingqayizivele yomakhenikha wamanzi echaza ukugeleza kwamanzi — uketshezi namagesi. Inama-subdisciplines amaningana, kufaka phakathi i-aerodynamics (ukutadisha komoya namanye amagesi uma ihamba) kanye ne-hydrodynamics (isifundo ngotshwala ngokuhamba). Amandla weFluid anezinhlobonhlobo zezicelo, kufaka phakathi amandla wokubala nezikhathi endizeni, ekunqumeni izinga lokuhamba kaphethiloli ngamapayipi, ukubikezela amaphethini wesimo sezulu, ukuqonda i-nebulae esikhaleni esiphakathi kanye nokufaka isikhombimsebenzisi se-fission isikhali, Amandla weFluid anikezela ngesakhiwo esisebenzayo — ngaphansi kwalezi zimiyalo ezisebenzayo-ezihlanganisa imithetho enezifiso nezinobudlova ezisuselwa ekulinganiseni kokugeleza futhi ezisetshenziselwa ukuxazulula izinkinga ezisebenzayo. Isixazululo senkinga yamandla kagesi ajwayelekile sibandakanya ukubalwa kwezindawo ezahlukahlukene zamanzi, njengokugeleza kwengcindezi, ingcindezi, nobukhulu bokushisa, njengemisebenzi yendawo nesikhathi.

Isicelo samahhala "Fluid Dynamics" sinomusa kakhulu, sine-interface enhle futhi elula. Ukukhetha okuhle kwesichazamazwi ephaketheni okuhlala kuseduze. Ukusuka lapho ungafunda khona izinto eziningi ezintsha nezijabulisayo, ngokwesibonelo, ukuthi:

Prandtl-Meyer fan fan
Umuntu othanda ukwanda okungaphezulu komoya, obizwa ngePrantl-Meyer fan fan, okuwumbala olula nhlangothi zombili, inqubo eyandisiwe eyenzeka lapho ukugeleza kwamandla okuphezulu kuphenduka ekhoneni le-convex. I-fan inenombolo engenamkhawulo yamaza we-Mach, aphambuka ekhoneni elibukhali. Lapho ukugeleza kuphenduka ekhoneni elibushelelezi neliyindilinga, la magagasi angangezwa emuva ukuze ahlangane endaweni ethile.

I-Newtonia fluid
Uketshezi lwaseNewtonia uketshezi lapho izingcindezi ze-viscous ezivela ngenxa yokugeleza kwalo, kuwo wonke amaphuzu, zihambelana ngokuqondile nezinga lezinhlobo sendawo — izinga lokushintshwa kwencazelo yalo ngokuhamba kwesikhathi. Lokho kufana nokusho ukuthi lawo mandla ahambelana nezinga lokushintshwa kwensiza ye-velocity velocity njengoba umuntu esuka kude nephuzu okukhulunywa ngalo ngezindlela ezahlukahlukene.

Wave impedance
I-wave impedance of a electromagnetic wave yisilinganiso sezingxenye eziguqukayo zezinsimbi zikagesi nezobuthe. Kwindiza ye-transverse-kagesi-kazibuthe (TEM) ehamba nge-homogeneous medium, ukufakwa kwamandla kwegagasi kuyo yonke indawo kuyalingana nokuvinjelwa okungaphakathi kwaphakathi nendawo. Ikakhulu, ngegagasi lendiza elihambahamba endaweni engenalutho, ukuminyana kwegagasi kuyalingana nokuvinjezelwa isikhala samahhala. Isimboli Z sisetshenziselwa ukuyimele futhi ivezwa ngamayunithi wama-ohms. Isimboli i-η (eta) singasetshenziswa esikhundleni se-Z sokufaka igagasi ukugwema ukudideka ngokufakwa kukagesi.
