Pfupisa nheyo yaBernoulli yakavakirwa pandima dzinotevera.
Context:Nheyo yaBernoulli ipfungwa inokosha mu fluid dynamics iyo inobatanidza dzvinyiriro, kumhanya uye kukwirira. Mutemo waBernoulli unoti kuwedzera kwekumhanya kwe fluid kunoitika panguva imwe chete nekuderera kwekumanikidza kwekumanikidza kana kuderera kwesimba re fluid. Mutemo uyu wakatumidzwa zita remusvomhu wekuSwitzerland uye nyanzvi yefizikisi Daniel Bernoulli, uyo akaburitsa mubhuku rake rinonzi Hydrodynamica muna 1738. Kunyangwe Bernoulli akaburitsa kuti kumanikidza kunoderera kana kumhanya kwekuyerera kuchikura, ndiLeonhard Euler muna 1752 akawana equation yaBernoulli muchimiro chayo chakajairika. Nheyo iyi inoshanda chete kune isentropic kuyerera: apo migumisiro yezviitiko zvisingachinjiki (zvakadai sekukanganiswa) uye zvisiri-adiabatic maitiro (semuenzaniso kupisa kwemhepo) zviduku uye zvinogona kuregererwa. Nheyo yaBernoulli inogona kubviswa panheyo yokuchengetwa kwesimba. Izvi zvinotaura kuti, mukuyerera kwakadzikama, uwandu hwemhando dzose dzesimba mumvura hwakafanana pamapoinzi ose asina masimba ane viscous. Izvi zvinoda kuti uwandu hwesimba rinotenderera, simba rinogona kuitika uye simba romukati rirambe risingachinji. Nokudaro kuwedzera kwekumhanyisa kwemvura - kunoreva kuwedzera kwesimba rayo rinotenderera (kumanikidzwa kwesimba) - kunoitika pamwe chete nekuderedzwa kwe (nhamba ye) simba rayo rinogona kuitika (kusanganisira kumanikidza kwemamiriro ezvinhu) uye simba remukati. Kana mvura ichiyerera ichibva mumudziyo, uwandu hwemhando dzose dzesimba hwakafanana nokuti mumudziyo simba pauniti yevhoriyamu (uwandu hwezvinhu zvinodzvinyirira uye simba rinokwezva ρ g h) rakafanana kwose kwose. Nheyo yaBernoulli inogonawo kuwanwa zvakananga kubva kuMutemo wechipiri waIsaac Newton weKufamba. Kana mvura shomanana ichiyerera ichibva munzvimbo ine kumanikidza kwakanyanya ichienda kunzvimbo ine kumanikidza kwakaderera, kumashure kunenge kuine kumanikidza kwakanyanya kupfuura kumberi. Ikoku kunopa simba rakazara pahuwandu, kuchikurumidzisa mumutsetse wetsetse. Zvikamu zvemvura zvinongodzorwa chete nokumanikidzwa uye uremu hwazvo. Kana mvura ichiyerera yakatwasuka uye ichitevedza chikamu chemutsetse unofamba nemvura, apo kumhanya kunowedzera kunogona kungova nokuti mvura iri pachikamu ichocho yakabva munharaunda yokumanikidzwa kwakakwirira ichienda munharaunda yokumanikidzwa kwakaderera; uye kana kumhanya kwayo kuchiderera, kunogona kungova nokuti yakabva munharaunda yokumanikidzwa kwakaderera ichienda munharaunda yokumanikidzwa kwakakwirira. Nokudaro, mukati memvura inoyerera yakatwasuka, kumhanya kukuru kunoitika apo dzvinyiriro yakaderera zvikuru, uye kumhanya kwakaderera zvikuru kunoitika apo dzvinyiriro yakaderera zvikuru.
Nheyo yaBernoulli ipfungwa inokosha mu fluid dynamics iyo inobatanidza dzvinyiriro, kumhanya uye kukwirira. Nheyo yaBernoulli inoti kuwedzera kwekumhanya kwechinhu chinenge chichiyerera kunoitika panguva imwe chete nokuderedzwa kwekumanikidzwa kana kuti kuderedzwa kwesimba rinenge richiyerera.
