4. Mapapiro endege akagadzirwa kuti ave nesimba guru rekusimudza , senge mufananidzo. Kana v iri kumhanya kwemhepo uye P iri kumanikidzwa kwemhepo, saka maererano nemutemo weBernoulli, dhizaini yacho yakagadzirwa kuitira kuti …
mhinduro
Kuti mapapiro endege asimukire kumusoro, kusundirwa kwemhepo pasi pebapiro kwakakura kupfuura simba rekusundirwa riri pamusoro pebapiro.
Simba rekusundidzira riri pasi pebapiro rakakura kana kumanikidzwa kwemhepo pasi pebapiro kwakanyanya. P = F / A, apo kumanikidzwa kweP kwakanangana zvakananga neF. Kana kumanikidzwa kwacho kwakanyanya, simba racho rinowedzerawo.
Nheyo yaBernoulli inoti kumanikidzwa kwemhepo pasi pebapiro kwakanaka kana kumhanya kwemhepo pasi pebapiro kuri kudiki.
v A > v B s o kuti P A <P B
1. Mubvunzo: Chii chinonzi musimboti waBernoulli?
Mhinduro: Nheyo yaBernoulli inoti pakuyerera kwemvura isina kufambiswa nemhepo, kuwedzera kwekumhanya kwemvura kunoitika panguva imwe chete nekuderera kwekumanikidzwa kwakasimba kana kudzikira kwesimba rinokwanisa kushandiswa nemvura.
2. Mubvunzo: Pfungwa yaBernoulli ine chekuita sei nekuchengetedzwa kwesimba?
Mhinduro: Pfungwa yaBernoulli inoratidza kuchengetedza simba kuti mvura ifambe zvakanaka. Simba rose riri muhurongwa hwemvura inoyerera zvakanaka rinochengetwa. Sezvo simba remvura (kumhanya) richiwedzera, simba rayo (kumanikidzwa) rinoderera, uye zvinopesana.
3. Mubvunzo: Sei mapapiro endege aine chikamu chepamusoro chakakombama uye chikamu chepasi chakati sandara?
Mhinduro: Mapapiro endege (airfoils) akagadzirwa nepamusoro pakakombama uye pasi rakati sandara kuti kufamba kwemhepo kukurumidze kupfuura pamusoro kupfuura pasi. Sekureva kwemutemo waBernoulli, izvi zvinokonzera kumanikidzwa kwakaderera pamusoro uye kumanikidzwa kwakakwira pasi, zvichikonzera kusimudzwa.
4. Mubvunzo: Ko musimboti waBernoulli unotsanangura sei mashandiro e venturi meter?
Mhinduro: Chiyero che venturi chine chikamu chakamanikana apo kumhanya kwemvura kunowedzera, zvichikonzera kudzikira kwedzvinyiriro. Nekuyera musiyano wekumanikidzwa pakati pezvikamu zvakamanikana nezvisina kumanikana, munhu anogona kuona mwero wekuyerera kwemvura, achishandisa musimboti waBernoulli.
5. Mubvunzo: Sei bhora renhabvu rinotenderera richikombama munzira yaro?
Mhinduro: Izvi zvinokonzerwa neMagnus effect. Bhora parinotenderera, rinokurumidzisa mhepo kune rumwe rutivi uye rinoita kuti iderere kune rumwe rutivi. Zvichibva papfungwa yaBernoulli, izvi zvinoita kuti pave nekusiyana kwekumanikidzwa, zvichiita kuti bhora rikotame.
6. Mubvunzo: Pfungwa yaBernoulli ine chekuita sei nekushanda kweatomizer kana sprayer yezvinonhuwira?
Mhinduro: Kana mhepo ikapfurwa pamusoro pechubhu yeatomizer, inokurumidza, zvichiita kuti pave nenzvimbo ine kumanikidzwa kwakaderera. Kumanikidzwa kwakakwira pasi kunosundira mvura pamusoro pechubhu, uko inosangana nemhepo inofamba nekukurumidza uye inopfapfaidzwa mumhute diki.
7. Mubvunzo: Denga rakakombama pachivako ringakonzera sei njodzi kana paine mhepo ine simba?
Mhinduro: Kana mhepo ine simba, mhepo inofamba nekukurumidza pamusoro pedenga rakakombama zvichienzaniswa nepamusoro pakati sandara. Mhepo inofamba nekukurumidza pamusoro penzvimbo yakakombama inoita nzvimbo ine kumanikidzwa kwakaderera, zvichienderana nepfungwa yaBernoulli. Kusiyana uku kwekumanikidzwa kunogona kukonzera kusimudza, zvichikanganisa denga.
8. Mubvunzo: Sei mahwindo akavhurika mumotokari inofamba achikonzera kubhururuka kwemapepa ari mukati?
Mhinduro: Mota painofamba, kumhanya kwemhepo kunze kwakakwira kupfuura mukati memota. Izvi zvinoita kuti pave nemusiyano wekumanikidzwa nekuda kwemutemo waBernoulli, zvichiita kuti mapepa atenderere sezvo mhepo ichiedza kuenzanisa kumanikidzwa.
9. Mubvunzo: Pfungwa yaBernoulli ingatsanangura sei kukwidzwa kunoitwa vanosurfa nekite?
Mhinduro: Kite, kana ikakomberedzwa nemhepo, inokurumidza kufamba kwemhepo pamusoro payo, zvichiita kuti pave nenzvimbo ine kumanikidzwa kwakaderera. Kumanikidzwa kwakakwira pasi pekite, zvichienzaniswa nekumanikidzwa kwakaderera pamusoro, kunoita kuti vanhu vanosvetukira mukite vasimudzwe kubva mumvura.
10. Mubvunzo: Sei keteni reshawa richidhonzwa mukati kana mvura yavhurwa?
Mhinduro: Mvura inopisa inobva mushawa inodziya mhepo, zvichiita kuti ikwire uye inokurumidza kuyerera kwemhepo munzvimbo yeshawa. Mhepo iyi inofamba nekukurumidza inoita kuti mukati meshawa muve nekumanikidzwa kwakaderera zvichienzaniswa nekunze. Nekuda kweizvozvo, keteni reshawa rinodhonzwa mukati nekuda kwekusiyana kwekumanikidzwa kunotsanangurwa nepfungwa yaBernoulli.
