LMEC-11 Measuring Liquid Viscosity - Falling Sphere Method

Tlhaloso e Khutšoanyane:

Liquid viscosity coefficient, eo hape e tsejoang e le viscosity ea metsi, ke e 'ngoe ea thepa ea bohlokoa ea mokelikeli, e nang le ts'ebeliso ea bohlokoa ho boenjiniere, theknoloji ea tlhahiso le meriana.Mokhoa oa bolo o oang o loketse haholo bakeng sa thuto ea liteko ea baithuti ba bacha le ba sophomores ka lebaka la ts'ebetso ea eona e hlakileng ea 'mele, mohopolo o hlakileng le lits'ebetso tse ngata tsa liteko le likahare tsa koetliso.Leha ho le joalo, ka lebaka la tšusumetso ea li-stopwatch tsa letsoho, parallax le bolo e oelang bohareng, ho nepahala ha tekanyo ea lebelo le oeleng ha ho phahameng nakong e fetileng.Sesebelisoa sena ha se boloke feela ts'ebetso le litaba tsa liteko tsa sesebelisoa sa pele sa liteko, empa hape se eketsa molao-motheo le mokhoa oa ts'ebeliso ea laser photoelectric timer, e eketsang boholo ba tsebo, e ntlafatsang ho nepahala ha tekanyo, le ho kenyelletsa ntlafatso ea thuto ea liteko.

1. Adopt laser photoelectric heke ea nako, nako ea tekanyo e nepahetseng haholoanyane.
2. Ka photoelectric heke boemo ba calibration pontšo, ka konopo qala ho thibela methatiso e fosahetseng.
3. Ntlafatsa moralo oa lesela le oelang, lesoba le ka hare la 2.9mm, sebaka sa bolo e oelang se ka hlophisoa hantle, e le hore libolo tse nyane tsa tšepe le tsona li ka khona.

Liteko
1. Ho ithuta mokhoa oa liteko oa ho lekanya nako le lebelo la ho sisinyeha ha ntho ka laser photoelectric sensor.
2. Ho lekanya coefficient ea viscosity (viscosity) ea oli ho sebelisa mokhoa oa ho oela ka bolo e nang le foromo ea stokes.
3. Ho ela hloko maemo a liteko bakeng sa ho lekanya coefficient ea viscosity ea lino ka mokhoa oa bolo e oelang le ho etsa litokiso ha ho hlokahala.
4. Ithute tšusumetso ea li-diameter tse fapaneng tsa libolo tsa tšepe ka mokhoa oa ho lekanya le liphello.
