Iko viscosity yemvura ndiyo chiyero chayo kuramba kuyerera.
Inzvimbo yemvura inotara huwandu hwesimba rinodiwa kuifambisa. Iyo yakakwirira viscosity, iyo inowedzera simba rinodiwa kufambisa mvura.
Iyo viscosity yemvura inobatwa nekupisa kwayo. Kudziya kwemvura, kuderera kwayo viscosity. Iyo mvura inotonhora, iyo inowedzera viscosity yayo.
Iyo viscosity yemvura inobatwawo nekumanikidza kwayo. Kuwedzera kwesimba, ndiko kuwedzera kwemvura inopenya.
Iyo viscosity yemvura inogona kuyerwa ne viscometer. Viscometer mudziyo unoyera kumira kwemvura pakuyerera. Iyo viscosity yemvura chinhu chakakosha mukushandisa kwakawanda. Semuenzaniso, viscosity yemvura inogona kushandiswa sarudza huwandu hwesimba rinodiwa kuti rifambise nepapombi.
Viscosity mufizikisi ndechimwe chezvimiro zvenyaya iyo mafambiro emamorekuru ane ruremekedzo kune akatenderedza mamorekuru anosangana, nekuda kwesimba remukati memolecular, simba rinopokana: muzvakaoma ndiro rakakwirira, asi rakaderera mune zvinwiwa nemagasi. Kana tikanyudza muviri wekune imwe nyika mumvura iri kutariswa, ichasangana nepikisi iyo simba rinosiyana zvichienderana nedhigirii remvura ye viscosity.
Molasses, semuenzaniso, ine viscosity yakakwirira kupfuura mvura nekuti inodzivirira kuyerera.
Pane nzira dzakawanda dzaangashandisa munhu kuyera viscosity yemvura, iri nyore uye yakatwasuka ndeyekudonhedza bhora reimwe dhayamita mumudziyo wakajeka une mvura ine viscosity iri kuedza kuona.
ATTENTION: iyo inodzokororwa ye viscosity inonzi fluidity, chiyero chekutsvedzerera.
Viscosity chinhu chakakosha pakuona masimba anofanirwa kukunda kana zvinwiwa zvichishandiswa pakuzora uye kutakurwa mumapombi. Naizvozvo zvichave zvakakosha kuti isu tiite pasistand rudzii rwemvura Besa® vharafu ichave ichishanda pamwe chete, sezvo kupesana pakati pemadziro epombi uye mvura inoyerera kuburikidza nayo inokanganisa kushanda kwevhavha.
Inodzora kuyerera kwemvura mukati processes akadai kupfapfaidza, jekiseni molding uye pamusoro pekuisa.
Dynamic viscosity
Ngatitarisei ndege mbiri, dzakaparadzaniswa nemvura (tembiricha inodzorwa) uye inofambirana ne each imwe, imwe yakamira uye imwe ichiiswa pasi pesimba rinosundidzira/kuridhonza richifambirana neimwe ndege.
Zvichienderana nemvura yatinoshandisa kupatsanura ndege mbiri idzi, uye tichigara tichishandisa simba rimwechete kufambisa imwe yendege mbiri, tichaona kuti kumhanya kwendege kunosiyana zvichienderana nemvura yatinenge tasarudza.
Generalising tine:
A (m^2)= nzvimbo yendege dzakafanana
y (m)= chinhambwe pakati pendege mbiri idzi
F (N)= simba rinoshandiswa kundege inofamba
u (m/s^2)= kumhanya kwendege inofamba
τ = tangential simba
The tangential force ichave inversely proportional kune chinhambwe chiri pakati pendege mbiri uye yakanangana nekumhanya.
Kusuma izwi rekuti velocity kunoomesa zvinhu, nekuti chete nedzidziso ndiyo musiyano wevelocity linear.
Units zveyero
MuInternational system viscosity inoyerwa mukati pascals (Pa s) iyo yakaenzana ne poiseuille (PI), dzimwe nguva yemafuta ekuzora iyo CGS system inoshandiswawo, kureva centipoise (cP)
1 Pa s = 1 PI
1 cP = 1 mPI
Kinematic Viscosity: 1 cSt (centiStokes) = 10-6 m2/s
