Umthetho Bernoulli kaThixo. Mane nangempumelelo

Kuninzi yehlabathi elisingqongileyo nothobela imithetho physics. Akumangalisi oku, kuba igama elithi "physics" livela kwigama lesiGrike elithetha "indalo." Ke enye le mithetho osoloko esebenza okungeenxa zonke kuthi, lo ngowona mthetho ulawula yonke Bernoulli.

Ngokwawo, umthetho isebenza utshitshiseke siseko yolondolozo amandla. Le ukutyhilwa ivumela ukuba amnike ukuqonda entsha iziganeko ezininzi ngaphambili kakuhle edumileyo. Ukuze siqonde kakuhle umthetho elula ngokwaneleyo ukuba ukukhumbula kumsinga oqukuqelayo. Apha iyabaleka, uyabaleka phakathi kwamatye, amasetyana kunye neengcambu. Kwezinye iindawo kuba banzi, endaweni kakade. Kusenokwenzeka ukuba kuqatshelwe ukuba apho esihlambo ngokubanzi, amanzi abetheka ngokucothayo, nosele, amanzi abetheka ngokukhawuleza. Lo mgaqo Bernoulli, nto leyo omisela ubudlelwane phakathi xi emfuleni fluid kunye isantya sokuqukuqela enjalo.

Noko ke, iincwadi physics kubhaliwe uqulunqe noko ngokwahlukileyo, kwaye bababalisela hydrodynamics, hayi umsinga. Xa isohlwayo ngokwaneleyo uhlobo yomthetho ka Bernoulli ingashwankathelwa ngale ngobuwena - yengcinezelo ulwelo aqukuqela kumbhobho ingaphezulu apho uqina yayo ungaphantsi and vice versa apho phezulu uqina, xi ingaphantsi.

Ukuze uqinisekise kwanele ukwenza imifuniselo ezilula. Kuyimfuneko ukuba uthathe iphepha nivuthele ecaleni kwawo. Paper liphuma phezulu kwicala ecaleni apho umoya kwemali.

Yinto elula kakhulu. Njengoko umthetho Bernoulli kaThixo, apho phezulu isantya, xi ingaphantsi. Ngenxa yoko, ecaleni umphezulu sheet, apho ukuhamba umoya, xi mncinci, yaye ngaphantsi sheet apho kungekho flow umoya, xi omkhulu. Nalu uluhlu kwaye liphuma ngendlela apho xi asezantsi, oko kukuthi, apho umlambo umoya udlula.

Isiphumo ngasentla lisetyenziswa kubomi bemihla ngemihla kunye nobugcisa. Ngokomzekelo singakwazi ingqalelo umpu okanye Airbrush. Kwezi zohlobo zisetyenziswa, enkudlwana cross-icandelo kunabanye. Loo nto ke ubukhulu enkulu, kuqhotyoshelwe isikhongozelo ngepeyinti, ngokwale yecandelo ezincinane emnqamlezweni, kunabela with Velocity phezulu emoyeni. Ngenxa umahluko ingcinezelo evela Ipeyinti engena umoya emfuleni kulo mlambo ikhutshelwa wobuso ziipeyintiwe.

Lo mgaqo nako ukusebenza impompo. Enyanisweni, oko kuchazwe ngentla, kwaye i impompo.

Akukho umdla kangako umthetho Bernoulli njengoko isicelo kutsalwe kwimigxobhozo. Njengesiqhelo, yonke into ilula kakhulu. Wetlands inxibelelanisa izisele engasemlanjeni. Ukugeleza umlambo, apha kumgxobhozo apho. Kwakhona kukho umahluko xi, yaye amanzi emlanjeni iqala some ukusuka Amathafa sezwe. Senzeka umboniso olunyulu yomthetho ye physics.

Ifuthe oku wesinxibo nezonakalisayo. Umzekelo, ukuba iinqanawa ezimbini iza kuba kufuphi enye kwenye, ukuba uqina amanzi iya kuba ngaphezulu phakathi kwabo kunomnye. Ngenxa yoko, kukho amandla ezongezelelweyo ukuze idale umtsalane iinqanawa omnye komnye, yaye intlekele iya kuba kunqandwa.

Ngaba zonke kunokuthiwa ukuchaza ngohlobo neefomula, kodwa quadratic Bernoulli ukubhala akuyomfuneko ukuba ukuqonda ubunjalo ebonakalayo kule meko.

Kuba ukuqonda ngcono sinikela umzekelo omnye ngaphezulu ukusetyenziswa echazwe ngokomthetho. Bonke amele rocket. Ukwigumbi ezizodwa ukutshiswa amafutha, kwaye kwasekwa jet umlambo. Ukukhawulezisa isebenzisa yinxalenye ngokukhethekileyo tapered - umlomo. Kukho umlambo igesi olukhawulezisiweyo baze ngokwenjenjalo - Growth jet wakwakhe.

Zininzi iindlela ezahlukeneyo ngokusebenzisa umthetho Bernoulli kule ubuchule, kodwa ukuba uqwalasele kubo sikhokelo eli nqaku nje akunakwenzeka.

Ngoko ke, baqulunqe umthetho Bernoulli, banikwe ingcaciso yohlobo ebonakalayo iinkqubo ezenzekayo kwi kuhlobo ubuchwepheshe kunye nemizekelo izicelo yalo mthetho kunokwenzeka.
