LMEC-11 Kuyera Liquid Viscosity - Inodonha Sphere Method Inoratidzwa Mufananidzo

LMEC-11 Kuyera Liquid Viscosity - Falling Sphere Method

Tsanangudzo Pfupi:

Liquid viscosity coefficient, inozivikanwawo semvura viscosity, chimwe chezvinhu zvakakosha zvemvura, ine zvakakosha mashandisirwo muinjiniya, tekinoroji yekugadzira uye mushonga.Nzira yebhora rinodonha yakanyatsokodzera dzidziso yekuedza yevachangopedza uye sophomores nekuda kwechiitiko chayo chiri pachena chemuviri, pfungwa yakajeka uye maitiro akawanda ekuedza uye zvinyorwa zvekudzidzisa.Nekudaro, nekuda kwesimba remanyorero stopwatch, parallax uye bhora richidonha kubva pakati, iko kurongeka kwekudonha kuyerwa kwekumhanya hakuna kukwirira munguva yakapfuura.Ichi chiridzwa hachingochengete chete kushanda uye zviyedzo zvemukati wechiyedzo chepakutanga, asi zvakare chinowedzera musimboti uye nzira yekushandisa yelaser photoelectric timer, iyo inowedzera huwandu hweruzivo, inonatsiridza huroyi hwekuyera, uye inosanganisira yemazuva ano yekuyedza dzidziso.

Features

1. Adopt laser photoelectric gedhi nguva, yakanyatsojeka kuyerwa nguva.
2. Ne photoelectric gedhi chinzvimbo calibration chiratidzo, ine bhatani rekutanga kudzivirira kukanganisa.
3. Kuvandudza dhizaini yekudonha kwebhora, gomba remukati 2.9mm, bhora rinodonha rekutarisa rinogona kurongeka, kuitira kuti mabhora madiki esimbi anogona zvakare.
cheka zvakanaka danda relaser, wedzera nguva yekudonha uye uvandudze kuyerwa kwechiyero.

Miedzo
1. Kudzidza nzira yekuedza yekuyera nguva uye velocity yechinhu chinofamba nelaser photoelectric sensor.
2. Kuyera viscosity coefficient (viscosity) yemafuta uchishandisa nzira yebhora inodonha ne stokes formula.
3. Kucherechedza maitiro ekuedza ekuyera viscosity coefficient yezvinwiwa nenzira yebhora rinodonha uye kugadzirisa kana zvichidikanwa.
4. Dzidza pesvedzero yemadhayamita akasiyana emabhora esimbi pachiyero chekuyera nemhedzisiro.
