Mu fomula mukunena, P ayimirira chifukwa cha kupanikizika kwapafupi pamtunda h ndi kumene liwiro lamadzimadzi ndi v. Kuyitcha kuti hydrostatic kumawoneka ngati dzina lolakwika (popeza madzi akuyenda), koma chifukwa chake ndi chizolowezi chotchedwa "dynamical pressure" mawu akuti ρv2/2.

Komanso, mfundo ya Bernoulli ndi yotani m'mawu osavuta?

Mfundo ya Bernoulli ndi lingaliro la mphamvu zamadzimadzi. Limanena kuti liŵiro la madzimadzi likamawonjezereka, kuthamanga kumachepa. Chonde dziwani kuti izi zikutanthauza kusintha kwa liwiro ndi kuthamanga panjira imodzi yoyenda ndipo sizikugwira ntchito pamayendedwe awiri osiyanasiyana pa liwiro losiyana.

Kupatula pamwambapa, njira ya equation ya Bernoulli ndi chiyani? Pressure + ½ density * square of the velocity + density * mphamvu yokoka. mathamangitsidwe* kutalika = mosalekeza. The equation kwalembedwa. P + ½ ρ v2 + ρ g h = nthawi zonse. Izo zikunena zonse fomula imagwira pa dongosolo, teremu iliyonse imatha kusintha koma kuchuluka kwake ndi komweko.

Ndiye, kodi equation ya Bernoulli imatanthauza chiyani?

Bernoulli Equation. The Bernoulli Equation akhoza kuonedwa kuti ndi mawu a kusunga mphamvu mfundo yoyenera madzi oyenda. Khalidwe khalidwe kuti ndi nthawi zambiri amalembedwa ndi mawu akuti "Bernoulli zotsatira" ndi kutsika kwa kuthamanga kwamadzimadzi m'madera omwe kuthamanga kwake kumathamanga ndi kuchuluka.

Kodi mfundo zinayi za Bernoulli ndi ziti?

Mmodzi mwa ambiri wamba tsiku lililonse kugwiritsa ntchito mfundo ya Bernoulli ali mu ndege. Njira yaikulu kuti Mfundo ya Bernoulli ntchito mu ndege ndege amagwirizana ndi kamangidwe ka mapiko a ndege. M'mapiko a ndege, pamwamba pa phiko lake ndi lopindika pang'ono, pamene pansi pa phikolo ndi lathyathyathya.
