Kinematic viscosity. Urume hurongwa

Kinematic viscosity chinhu chinokosha chinoratidza gasi zvose uye zvokunwa vezvenhau chaiko. Nhamba iyi rwakakosha Pakusarudza zvuva of zvinofamba nezvishoma uye mutoro yavanofanira kuona. Sezvaunoziva, munyika yedu paine kufamba mudenga kana hwemvura kwezvakatipoteredza. Saka nomusi zvinofamba muviri nguva dzose kukanganisa simba Vector pakatarisana kutungamirirwa kwebasa zvinhu pachavo. Nokudaro, kumusoro ari kinematic viscosity ari svikiro, zvikuru mutoro kune yakasimba. Chii yezvakaita zvivako zviri mvura uye magasi?

Kinematic viscosity, rinorondedzerwa so womukati kukweshera imhaka tichimhanya kuchinjwa mumiririri mamorekuru perpendicular kutungamirirwa inofamba pakati akaturikidzana ayo ane aimhanya siyana. Somuenzaniso, mune mvura neimwe STRUCTURAL dzakabatana (Morekuru) akapoteredzwa kumativi ose nevavakidzani vayo pedyo dziri anenge kure akaenzana dhayamita yavo. Mumwe Morekuru yemakomo kumativi vanonzi zvakanyatsoenzana nzvimbo, asi achitora kupomba nevavakidzani vayo, zvinoita rakapinza kusvetuka kurutivi rutsva nzvimbo oscillation. A STRUCTURAL Unit yechipiri, mumwe fuma yakadai ane nguva yokuchinja nzvimbo dzokugara yake anenge mamiriyoni zana, zvichiita pakati akasvetuka kubva kumazana ezviuru zvakasiyana. Chokwadi, chikuru ndicho samolecular kukurukurirana, kashoma kuti mufambo mumwe STRUCTURAL Unit uye, naizvozvo, vakawanda fuma kinematic viscosity.

Kana morekuru chenguva zvimwewo mauto chiito chimwe pedyo akaturikidzana, ipapo vatungamirire PARTICIPLE kaviri zvikuru misha kuti kupiwa chairema nguva pane negwara. Saka, zviri kushandiswa runobva kutsvakatsvaka zvakarongeka kufamba pane imwe kumhanya, zvichienderana mauto kuita pairi. Kwakadaro yokusafa viscosity, semuenzaniso, motokari anonhuwirira. Pane Zvinokoshawo kuti vasiyana PARTICIPLE pasi kukurukurwa zvokunze mauto kuita basa iri inoitika tisingabatanidzi ari akaturikidzana kuburikidza iyo akakudzvinya ari Morekuru. ekisiposha kwakadaro pakupedzisira zvinowedzera mwero chafariz kurongwa inofamba pakati nezvimedu, izvo haachinji nguva. Nemamwe mashoko, Urume ndima inozivikanwa yunifomu pasinei kuramba uchinzwa zvimwewo mauto kwakasiyana-siyana nokuti zvinodzikamiswa ane womukati nemishonga zvinhu akaturikidzana kuti kunyatsotaura inorondedzera kinematic viscosity.

Sezvo tembiricha kunowedzera mufambo pakati mamorekuru hunotanga kuwedzera, iyo inotungamira dzimwe kuderera ari kurwisa zvinhu akaturikidzana, sezvo chinhu fuma preheated mamwe mamiriro ezvinhu akanaka ari pachena kwebasa nezvimedu nenzira iri Zvakarurama simba. Izvi zvinogona kufananidzwa nzira munhu nyore kuzvimbandidzira kuburikidza randomly zvinofamba evanhu pane wakaiswa. A chinokosha chinoratidza kinematic viscosity, akayera mu Pascals kana Stokes-mumasekonzi vane polymer mhinduro. Izvi imhaka kuvapo kwavo nemamiriro refu samolecular ngetani vari nokuramba wakaomerera panzira zvakabatana. Asi kuwedzera tembiricha yevanhu viscosity yavo kunoderedza nokukurumidza. Kana kudzvanya pamusoro epurasitiki filamentary wake bizarrely zvakanyatsobatana mamorekuru nechisimba kutora mutsva nzvimbo.

The viscosity of gasi ari tembiricha 20 ° C uye mumhepo kumanikidzwa 101,3 Pa iri sezvakarayirwa 10 ^-5 Pa * s. Somuenzaniso, mashoko kinematic viscosity mhepo, nehelium, okisijeni uye rehydrogen mumamiriro ezvinhu akadaro achava vakaenzana azvaitwa kune 1.82 10 ^-5; 1.96 * 10 ^-5; 2.02 * 10 ^-5; 0.88 * 10 ^-5 Pa s. A mvura nehelium kazhinji ane inoshamisa superfluid ehupfumi. Fani iyi, yakawanikwa ne Academician PL Kapitsa iri chokwadi kuti basa nesimbi kudaro uwandu hwezvinhu zvose zvabatanidzwa. ezvinhu ane anenge asina viscosity. Nokuti iye, mufananidzo uyu zvachose razero.
