Aiki ruwa matsa lamba. Mun zana karshe

Don magance matsalar da "m matsa lamba" fara da classic misalai da hankali, matsa zuwa cikin mafi hadaddun da m ga wannan. Domin a cylindrical jirgin ruwa, wanda bango tsananin tsaye, a kwance kasa, da hydrostatic matsa lamba na ruwa zuba a kan tsawo h ga kowane kasa ma'ana zai zama canzawa. A dabara domin kirga wannan yawa za su bayyana a matsayin p = rgh, a cikinsa r - yawa daga ruwa. g - hanzari nauyi. h - tsawo daga cikin ruwa shafi. The darajar p ga duk maki a kan tushe na wannan.

Gabatar a cikin jirgin ruwa kasa zuwa yankin na dabara S, wanda zai iya lissafta a matsa lamba karfi F. Tun da ruwa matsa lamba a kan kasa da jirgin ruwa a kowane batu na daya, da ma'ana ƙarshe zo da dabara F = rghS.

Abu ne mai sauki, a lura cewa, a wannan yanayin da matsa lamba da karfi zuwa kasa ne daidai da nauyin da ruwa zuba a cikin cylindrical jirgin ruwa dace siffar. Yana alama paradoxical, amma shi yana da kimiyya da kuma ma'ana bayani cewa da dabara F = rghS aiki saboda kayayyakin sosai daban-daban siffofin. A wasu kalmomin, a karkashin wannan dabi'u na S - kasa zuwa yankin da kuma h - da tsawo na ruwa matakin na ruwa matsa lamba a kan tushe na wannan domin dukan tasoshi, ko da kuwa wanda ruwansa da girma kowane mutum jirgin ruwa. The nauyi na ruwa a zahiri cika a cikin tasoshin da wani siffar da kuma iya zama karami, kuma mafi girma daga matsa lamba sojojin a kan kasa, amma ko da yaushe gamsar da sama mulki.

Wadannan da asali manufa na kimiyyar lissafi don tabbatar da ka'idojin karshe a yi, Pascal shawara don amfani da na'urar, da ake kira da sunan kansa. Babban alama na wannan na'urar ne na musamman tsayawar, kyale gyara da kayayyakin daban-daban siffofi, wanda ba su da wani tushe. A kasa na receptacles aikin tam guga man da kasa farantin, wanda aka located a daya hannu na balance masaƙa.

Saita da baƙin ƙarfe nauyi ga kopin wani rocker da kuma fara cika da jirgin ruwa da ruwa. Lokacin da ruwa matsa lamba zai tilasta mafi girma daga nauyi na kaya masu nauyi, da ruwa zai bude farantin, kuma shi zai zuba daga wuce haddi. By aunawa da tsawo na ruwa shafi, yana yiwuwa yin lissafi da na lamba darajar ta matsa lamba tilasta kasa da kuma nauyi idan aka kwatanta da kaya masu nauyi.

Shan la'akari da yiwuwar cimma mafi girma matsa lamba sojojin karamin adadin ruwa, kawai kara tsawo na ruwa matakin na da shafi, yana yiwuwa ya ba da wani bayani ga wani ban sha'awa kwarewa, kamar yadda aka bayyana da Pascal.

Don saman murfi caulked sosai sabon ganga, cike fal da ruwa, shi da aka a haɗe zuwa wani dogon tube ta hanyar abin da ruwa aka zuba. A tube da karamin giciye sashe, wata biyu da kofuna na ruwa ya isa tada shafi na ruwa zuwa wani babba tsawo. A wani matsayi, wani sabon kyau quality-drum rurrushe kuma yanyanke. Ko da kuwa da yawan cika ruwa, wato ruwa shafi ya kara matsa lamba a kan kasa na ganga. A sakamakon haka, da m adadin karfi da ya kai ga katsewa na ganga da aka halitta.

Bambanci da real nauyi na ruwa matsa lamba sojojin a kan jirgin ruwa kasa saboda da biya diyya na karfi, wanda ya haddasa ruwa matsa lamba a jirgin ruwa bango. Wannan karkata daga cikin jirgin ruwa ganuwar take kaiwa zuwa da cewa wannan matsin lamba ne directed ko dai sama ko zuwa ƙasa, bi da bi, sakamakon da ma'auni tsarin.

Matattarã ciwon takaita upwardly shigarsu cikin ruwa matsa lamba a sama. An ban sha'awa kwarewa za a iya sanya ta shirya wani sauki kafuwa. Ya kamata a fixedly lazimta a fistan a saka Silinda, wanda ya wuce a cikin tube saka tsaye. Zubowar ruwan ta cikin bututu, ganin yadda ciko da sarari sama da fistan take kaiwa zuwa dagawa sama da Silinda.

Don takaita, manufar "matsa lamba" za a iya bayyana a matsayin rabo na karfi da cewa abubuwa perpendicular zuwa surface dangane da yankin. Single matsa lamba darajar ne daidai da daya Pascal (1 Pa) da kuma daidai mataki na karfi na daya Newton (N 1) da murabba'in mita (1 m).

Kamar yadda Pascal ta Law, da matsa lamba samu da ruwa (gas) da aka aika canzawa zuwa kowane batu na girma na ruwa (gas). Proper ruwa matsa lamba (gas) ne guda, a kuma wani tsawo. Tare da zurfin aka ƙara.
