Hydrostatic kumanikidzwa

Hydrostatic - mumwe hydraulic zvikamu kudzidza zvakanyatsoenzana ehurumende uye nemvura vachimanikidzwa zvakapararira munyika mvura pa zororo iri hukawanika siyana.

Hydrostatic kumanikidzwa - chinokosha pfungwa iri hydrostatics. Funga Vhoriyamu ane zvemasanga mvura mu zvakanyatsoenzana. Inside rino pepa pfungwa A uye mupfungwa kuiganhura nepakati achishandisa ndege nomunyika pfungwa A. In ichi ndege mugove nevamwe nzvimbo S uye muzinda panguva A. Ngatirangarirane kubvisa imwe hafu bhuku uye kutsiva simba nawo aita mari vasara, kuti counterbalancing simba F. Saka, mvura yechipiri hafu acharamba ari zororo.

Tava kutanga kuderedza nzvimbo S kuti nguva dzose dzinotaura A iri mukati maro. With rutapudzo pfungwa A yakakwana rinobatana munharaunda S. Zvino kumanikidzwa panguva A achapiwa pakutsvaga nzira P (A) = nevaNefirimu dF / DS apo DS uderedze razero.

Ipapo vomanikidza S papuratifomu, zvichava akaenzana uwandu kumanikidza kunoitwa dzose pfungwa kuva pemvura. Kureva, mune mamwe mazwi, p = F / S. Hydrostatic kumanikidzwa - svinga akaenzana quotient hondo F nzvimbo S.

Chikonzero hydrostatic kumanikidzwa vari uremu mvura uye kumanikidza iyo rinoshandisirwa mvura pamusoro. Saka, kumanikidza anokonzerwa kurema nemvura uye kwokunze kumanikidzwa - mhando hydrostatic kumanikidzwa. Kana Urume iri aiswe pisitoni uye anewo simba pauri, zvino, Chokwadi, mukati Urume kumanikidzwa vanomutswa. Under kwomuzvarirwo ezvinhu, mumhepo kumanikidza runonditsikirira nemvura. Kana kumanikidzwa pamusoro mvura pamusoro pazasi mumhepo kumanikidzwa, kumanikidza inonzi geji.

The mvura iri zvakanyatsoenzana kana ose kumanikidza mauto ndikaita chero zvakakwana diki vhoriyamu emura, muri mwero pamwe chete.

Funga pedyo hydrostatic kumanikidzwa uye ayo zvivako:

• Chero nguva, achisarudza atora mune mvura Vector hydrostatic kumanikidzwa rinotungamirirwa nechomukati cheBhuku kwayo uye perpendicular kusvika panzvimbo kusarudzwa muna chidzitiro.

Ngationei ratidza pfuma ichi: ngatiregei kufunga kuti pakona uko simba rinoshandiswa imwe nzvimbo, kwete achirurama mutsetse. Tinomiririra simba P sezvo P (kuipa), P (tangent). Ngationei zvokufungidzira kuti tangential zvinoriumba haasi razero, ipapo pasi wayo kufurirwa Urume anofanira unoyerera chinhu vachida, asi zviri pa zororo achitandadza. Nokudaro mhedziso yokuti tangent akaenzana razero uye kufurirwa kwepasi kunoitika perpendicular nzvimbo. The pfuma kunoratidzwa.

• Kwakakura pamusoro hydrostatic kufurira rakafanana kwose kwose.

Ngationei zvinoratidza ichi pfuma hydrostatic kumanikidzwa: kusarudza zvemasanga chinovhara mvura tetrahedron, vaviri iyo uwirirane ndege rinoronga ndege, uye wechitatu anosarudzwa pamadiro. Pechingoro kuwana netriangle zvakanaka. Zvakaitwa nemvura norumwe chiso kureva: X * (P), Y * (P), Z * (P) mudura chacho zvakanyatsoenzana, saka kuti zvachose mugumisiro kuitwa mauto ndiyo 0.

E * (x) = 0

X * (P) dz -CA * (P) of chivi = 0,

E * (Y) = 0, E * (Z) = 0

Z * (P) yori -CA * (P) of Kosi munhu = 0

zviri pachena kuti dz = of chivi, yori = of Kosi munhu

nokudaro: X * (P) = E * (P), Z * (P) = E * (P)

goho: X * (P) = Y * (P) = Z * (P) = E * (P)

The pfuma kunoratidzwa. Sezvo mutsetse akasarudzwa pamadiro, kuenzana ichi chinoshanda kuti chero chiitiko.

• The hydrostatic kumanikidzwa ndiyo Proportional kune udzamu zvakananga. With kuwedzera udzamu pfungwa kufurirwa izvozvo kuchawedzera, uye kuderera kudzama kunyudzwa - kuwedzera.

Chero nguva nemvura iri zvakanyatsoenzana, unoenderana zvinotevera mukana wokuti vanhu vanga: j + p / d = J (o) + peji (o) / d = H, apo J - batanidza pfungwa iyi, J (O) - batanidza pamusoro pemvura Urume, p, uye peji (o) - nokukwirira yembiru, g - nemvura chaiyo giravhiti, H - hydrohead.

Somugumisiro transformations tinowana: r = peji () + d [J (0) Kuzvarwa] kana p = S. (o) + GH

apo H - kudzama kunyudza munhu akapiwa pfungwa, uye GH - kwete kungova kurema mbiru mvura akaenzana kukwirira bare uye kuva munharaunda zvitsigiro chikwata. pfuma Ndiro zita hydrostatic kumanikidzwa Mutemo Pascal vake.
