LMEC-12 Kuyera Liquid Viscosity - Capillary Method

Tsanangudzo Pfupi:

Liquid viscosity haingoshandiswe zvakanyanya muinjiniya nekugadzira tekinoroji, asi zvakare inoita basa rakakosha mubiology nemushonga. Semuenzaniso, kuyera saizi yeropa viscosity chimwe chezviratidzo zvakakosha zvehutano hweropa remunhu. Kuenzaniswa nenzira yebhora rinodonha, mutemo wekuyerera we viscous fluid mu vertical capillary tube unoshandiswa mukuedza uku. Iyo ine mabhenefiti ediki sampuli saizi, akasiyana tembiricha mapoinzi uye yakakwirira kuyerwa kwechiyero. Kunyanya akakodzera yakaderera viscosity mvura, akadai mvura, doro, mvura, etc. Kushandisa chiridzwa ichi kwete chete kuwedzera ruzivo vadzidzi ', asiwo anokudziridza avo experimental kushanda kugona.
