I-viscosity yoketshezi iyisilinganiso sayo ukumelana nokugeleza.
Kuyisici soketshezi olunquma inani lamandla adingekayo ukuze lunyakaze. Lapho i-viscosity iphakeme, kudingeka amandla engeziwe ukuhambisa uketshezi.
I-viscosity yoketshezi ithintwa izinga lokushisa layo. Lapho uketshezi lufudumala, i-viscosity yalo iyancipha. Lapho uketshezi lubanda kakhulu, kulapho i-viscosity yalo iphakama.
I-viscosity yoketshezi nayo ithintwa ukucindezela kwalo. Lapho umfutho uphakeme, i-viscosity yoketshezi iyanda.
I-viscosity yoketshezi ingalinganiswa nge-viscometer. I-viscometer iyithuluzi elikala ukumelana koketshezi ukuze ligeleze. I-viscosity yoketshezi iyimpahla ebalulekile ezinhlelweni eziningi. Isibonelo, i-viscosity yoketshezi ingasetshenziselwa nquma inani lamandla adingekayo ukuyihambisa ngepayipi.
I-viscosity ku-physics ingenye yezakhiwo zendaba lapho ukunyakaza kwama-molecule maqondana nama-molecule azungezile kuhlangana khona, ngenxa yamandla e-intermolecular, amandla amelana: kokuqinile aphakeme kakhulu, kodwa aphansi kakhulu oketshezini namagesi. Uma sicwilisa umzimba wangaphandle oketshezini olucutshungulwayo, uzobhekana nokumelana namandla akhona ahluka kuye ngezinga le-viscosity yoketshezi.
I-Molasses, isibonelo, ine-viscosity ephakeme kunamanzi ngoba imelana kakhulu nokugeleza.
Ziningi izindlela umuntu angazisebenzisa ukuze alinganise i-viscosity yoketshezi, okulula futhi okuqondile kakhulu ukuwisa indilinga yobubanzi obuthile esitsheni esisobala esinoketshezi okubukeka kwayo umuntu azama ukukunquma.
QAPHELA: i-reciprocal of viscosity ibizwa ngokuthi i-fluidity, isilinganiso sokushelela.
I-viscosity iyisici esibalulekile ekunqumeni amandla okufanele anqobe lapho uketshezi lusetshenziselwa ukugcoba futhi luthuthwa ngamapayipi. Ngakho-ke kuyoba kubalulekile kithi ukuba ngaphansistand hlobo luni loketshezi BesaI-valve ® izobe isebenza nayo, njengoba ukungqubuzana phakathi kwezindonga zepayipi noketshezi olugeleza kulo kuthinta ukusebenza kokukhipha kwe-valve.
Ilawula ukungena koketshezi processnjengokufafaza, ukubumba umjovo kanye nokunamathiswa kwendawo.
I-viscosity enamandla
Ake sicabangele izindiza ezimbili, ezihlukaniswe uketshezi (izinga lokushisa elilawulwayo) futhi elihambisana no each enye, enye imile kanti enye ingaphansi kwamandla ayiphushayo/eyidonsa ihambisane nenye indiza.
Kuye ngoketshezi esilusebenzisayo ukuze sihlukanise izindiza ezimbili, futhi njalo sisebenzisa amandla afanayo ukuhambisa enye yezindiza ezimbili, sizothola ukuthi isivinini sendiza siyahlukahluka kuye ngoketshezi esilukhethile.
Ukuhlanganisa sinakho:
A (m^2)= indawo yezindiza ezihambisanayo
y (m)= ibanga phakathi kwezindiza ezimbili
F (N)= amandla asetshenziswa endizeni ehambayo
u (m/s^2)= isivinini sendiza ehambayo
τ = amandla e-tangential
Amandla e-tangential azolingana ngokuphambene nebanga eliphakathi kwezindiza ezimbili futhi alingane ngokuqondile nesivinini.
Ukwethula ithemu lesivinini kwenza izinto zibe nzima, ngoba ngokwethiyori kuphela ukuhluka komugqa wejubane.
Amayunithi wesilinganiso
Kuhlelo lwamazwe ngamazwe i-viscosity ikalwa ngo pascals (Pa s) okulingana ne-poiseuille (PI), ngezinye izikhathi kumafutha okugcoba uhlelo lwe-CGS luyasetshenziswa, okungukuthi i-centipoise (cP)
1 Pa s = 1 PI
1 cP = 1 mPI
I-Kinematic Viscosity: 1 cSt (centiStokes) = 10-6 m2/s
