Kushanda Urume kumanikidzwa. We vafunga

Kugadzirisa dambudziko "Urume dzvinyiriro" kutanga chaiwo mienzaniso uye zvishoma nezvishoma anozodzidza zvikuru kunzwisisa uye oma iyi. Nokuti mudziyo cylindrical, ane rusvingo tisingatauri kutwasuka, munhu chinjikira pasi, iyo hydrostatic kwokudzvinyirira kwomunhu nemvura akadururira mumhu ekurwisana nerimwe pasi pfungwa achava kuchinja. The yemaitiro nokuti pakuverenga ichi uwandu achaonekwa sezvo p = rgh, sezvamakaropafadzwa R - arambe achirema kuti mvura mvura; d - kumhanyisa regiravhiti; H - kureba emura mbiru. The ukoshi peji pfungwa zvose pasi iyeyo.

Kusuma kupinda mudziyo pasi kunharaunda yemaitiro S, mumwe anogona exchange nezvinodzvinyirira simba F. Sezvo mvura kumanikidza pasi mudziyo ose pfungwa yakafanana, vatiwo kuuya nzira F = rghS.

Zviri nyore kuona kuti iyi nyaya kuita simba kusvika pasi akaenzana kurema nemvura akadira munzvimbo cylindrical mudziyo kwakakodzera chimiro. Zvinoratidzika gangaidzo, asi ine musayenzi uye zvichinzwisisika achiti nzira F = rghS anoshandira nhumbi zvakasiyana chaizvo siyana. Nemamwe mashoko, pasi chete netsika S - bottom nzvimbo uye H - kukwirira emura chechetere emura kumanikidza pasi saizvozvo nhumbi dzose, pasinei nokuti rinokwana bhuku mudziyo mumwe nomumwe. The uremu emura chaizvoizvo yazara kupinda midziyo chero chimiro uye angava maduku uye kupfuura kumanikidza mauto pasi, asi nguva dzose kugutsa pamusoro mutemo.

Zvichitevera chikuru wefizikisi kuti asimbise yokungotaura ndezvipi zvinoitwa, Pascal vataurira kushandisa mudziyo, akadana zita rake. The chikuru chinoratidza mudziyo ichi chinokosha chemwenje, vachibvumira kugadzirisa midziyo zvakasiyana-siyana, izvo havana pasi. Pasi pangagara anoita zvakasimba waitsimbirira pasi ndiro, iyo iri imwe ruoko pachiyero danda.

Isa simbi uremu mukombe mumwe rocker uye vanotanga vazadze mudziyo nemvura. Kana Urume nevamwe kumanikidza kupfuura kurema Zviidzo, iyo mvura kuchaita kuzarura mundiro, uye ndakadurura zvakawandisa. By kuyera kukwirira mvura mbiru, zvinokwanisika kuverenga nhamba kukosha kwayo kufurira Hunoita nechepasi uye uremu achienzaniswa Zviidzo.

Kufungisisa mukana kuti vabudirire zvikuru kumanikidzwa mauto shoma mvura, chete kuwedzera kukwirira mvura pamwero mbiru, zvinokwanisika kupa tsananguro kuti chimwezve dzinonakidza ruzivo, sezvinotaurwa Pascal.

Pamusoro muvharo caulked emiti kwazvo itsva, akazadzwa kusvikira pamuromo nemvura, yakanga dzakabatanidzwa kumicheto refu kuburikidza nemvura dzakadururwa. The chubhu aiva duku muchinjikwa chikamu, peya mikombe mvura yakanga yakakwana kusimudza mbiru mvura rebei yakakwirira. Pane imwe nguva, mumwe mutsva anonyatsoita Drum Akaputsawo uye bvamburwa. Pasinei nokuwanda kwakazadza emura, kureva mvura mbiru yakawedzera kumanikidzwa pamusoro pazasi Upfu. Somugumisiro, mashoko dzinonetsa uwandu simba kuti zvakazoita kuti atsamwira ari mudziyo akasikwa.

Musiyano uye chechokwadi kurema Urume kumanikidza mauto ari mudziyo pasi nokuda zvaizopedza kwesimba, izvo zvinoita kuti mvura kumanikidzwa panguva mudziyo pamadziro. Kuti zvinodiwa mudziyo masvingo kunotungamirira kuti kumanikidza ichi chinotungamirwa kana kumusoro kana pasi, ukuwo, zvichiguma zvakanyatsoenzana mugadziriro.

Sekaiichi wakati ari kuderedza upwardly kaviri ari Urume kumanikidzwa kumusoro. An dzinonakidza ruzivo zvinogona kuitwa nokugadzirira nyore kugadzwa. Zvinofanira fixedly yakanamatira pamusoro pisitoni kuisa humburumbira, izvo zvinoenda chubhu vakatasva vertically. Kudira mvura kuburikidza chubhu, vachiona sezvo rokuzadza nzvimbo pamusoro pisitoni kunotungamirira ndokusimudza humburumbira.

Kuti muchidimbu, pfungwa "dzvinyiriro" rinogona kurondedzerwa se nhamba simba mabasa perpendicular pemvura pachinhu munharaunda yayo. Single kumanikidzwa mutengo akaenzana mumwe Pascal (1 Pa) uye runoenzanirana zviito simba rimwe Newton (N 1) paminiti mativi mita (1 m).

Maererano noMutemo Pascal vake, kumanikidza kwakaitirwa Urume (gasi) anotumirwa kuchinja nechimwe pfungwa bhuku emura (negasi). Yakafanira Urume kumanikidzwa (gasi) ndiro paneimwewo yakakwirira. With kudzama inowedzerwa.
