Isimiso sikaBernoulli
Bernoulli, isazi sefilosofi saseSwitzerland, isazi sezibalo, usosayensi wezokwelapha.Ungummeleli ovelele kakhulu womndeni wezibalo waseBernoulli (izizukulwane ezi-4 namalungu ayi-10).Wafunda ifilosofi nelogic eNyuvesi yaseBasel eneminyaka engu-16, futhi kamuva wathola iziqu ze-master in philosophy.Lapho eneminyaka engu-17-20, wafundela ubudokotela.Wathola iziqu zenkosi kwezokwelapha, waba udokotela ohlinzayo odumile futhi wakhonza njengoprofesa wokwakheka komzimba.Nokho, ngaphansi kwethonya likayise nomfowabo, ekugcineni waphendukela kwisayensi yezibalo.UBernoulli waphumelela emikhakheni eyahlukene.Ngaphezu komkhakha oyinhloko we-fluid dynamics, kunezilinganiso zezinkanyezi, amandla adonsela phansi, imijikelezo engavamile yamaplanethi, i-magnetism, izilwandle, amagagasi, njll.
UDaniel Bernoulli waqala ukuphakamisa ngo-1726: "Emoyeni wamanzi noma emoyeni, uma ijubane lincane, ukucindezela kuzoba kukhulu; uma isivinini sikhulu, ukucindezela kuzoba kuncane".Lokhu sikubiza ngokuthi "i-Bernoulli Principle".
Sibamba izingcezu ezimbili zamaphepha bese sishaya umoya phakathi kwalezi ziqephu ezimbili zephepha, sizothola ukuthi iphepha ngeke lintante liphume, kodwa lizompintshana ndawonye ngamandla;ngoba umoya phakathi kwamaphepha amabili ushaywa yithi ukuze ugeleze Uma isivinini sishesha, ukucindezela kuncane, futhi umoya ongaphandle kwamaphepha amabili awuhambi, futhi ukucindezela kukhulu, ngakho-ke umoya onamandla amakhulu. ngaphandle "cindezela" amaphepha amabili ndawonye.
Iisifuthoyenziwe ngesimiso sokugeleza okuphezulu nokucindezelwa okuphansi.
Vumela umoya uphume ngokushesha embobeni encane, ingcindezi eseduze nembobo encane incane, kanye nomfutho womoya endaweni ewuketshezi endaweni.isitshainamandla, futhi uketshezi lukhuphuka eduze kweshubhu elincanyana ngaphansi kwembobo encane.Umthelela wafuthwa ku-ainkungu.
