LMEC-12 Kuyera Liquid Viscosity - Capillary Maitiro
Liquid viscosity haina kungoshandiswa zvakanyanya muinjiniya uye yekugadzira tekinoroji, asi zvakare inoita basa rakakosha mu biology nemushonga. Semuenzaniso, kuyera saizi yeropa viscosity ndiyo imwe yezvakakosha zviratidzo zvehutano hweropa revanhu. Inofananidzwa neinowira bhora nzira, kuyedza uku kunoshandisa kuyerera mutemo weiyo viscous fluid mune yakatwasuka capillary chubhu. Iine zvakanakira shoma sampuro yakawanda, akasiyana tembiricha mapoinzi uye yakanyanya kuyerwa kurongeka. Inonyanya kukodzera zvinwiwa zvine diki viscosity coefficient, senge mvura, doro, mvura uye zvichingodaro.
Kuedza
1. Nzwisisa mutemo wePoiseuille
2. Dzidza maitiro ekuyera viscous uye yepasi tension coefficients yemvura uchishandisa Ostwald viscometer
