LMEC-11 Kuyeza Viscosity Yamadzimadzi - Falling Sphere Method

Kufotokozera Kwachidule:

Liquid viscosity coefficient, yomwe imadziwikanso kuti viscosity yamadzimadzi, ndi imodzi mwazinthu zofunika kwambiri zamadzimadzi, zomwe zimakhala ndi ntchito zofunika paukadaulo, ukadaulo wopanga ndi mankhwala.The kugwa mpira njira yabwino kwambiri kwa experimental chiphunzitso cha atsopano ndi sophomores chifukwa cha zochitika zake zoonekeratu thupi, lingaliro lomveka ndi ntchito zambiri experimental ndi nkhani maphunziro.Komabe, chifukwa cha chikoka cha stopwatch yamanja, parallax ndi mpira ukugwa pakati, kulondola kwa kuyeza kothamanga sikuli kokwera m'mbuyomu.Chida ichi sichimangokhala ndi ntchito ndi zoyeserera za chipangizo choyambirira choyesera, komanso chimawonjezera mfundo ndi njira yogwiritsira ntchito laser photoelectric timer, yomwe imakulitsa kuchuluka kwa chidziwitso, imakulitsa kulondola kwa kuyeza, ndikuphatikiza kusinthika kwamaphunziro oyesera.

Mawonekedwe

1. Pezani nthawi yachipata cha laser photoelectric, nthawi yoyezera yolondola.
2. Ndi chithunzi cha photoelectric pachipata malo calibration, ndi batani loyambira kuti mupewe kuyesedwa molakwika.
3. Limbikitsani mapangidwe a mpira wakugwa, dzenje lamkati la 2.9mm, mawonekedwe a mpira wakugwa amatha kukonzedwa bwino, kuti timipira tating'onoting'ono tachitsulo
kudula bwino mtengo wa laser, kukulitsa nthawi yakugwa ndikuwongolera kulondola kwa muyeso.

Zoyesera
1. Kuphunzira njira yoyesera yoyezera nthawi ndi liwiro la kuyenda kwa chinthu ndi laser photoelectric sensor.
2. Kuyeza makulidwe a viscosity coefficient (viscosity) yamafuta pogwiritsa ntchito njira ya mpira wakugwa ndi formula ya stokes.
3. Kuwona mikhalidwe yoyesera kuyeza kukhuthala kwamadzimadzi ndi njira ya mpira wakugwa ndikuwongolera ngati kuli kofunikira.
4. Phunzirani mphamvu ya ma diameter osiyanasiyana a mipira yachitsulo pa ndondomeko ya kuyeza ndi zotsatira.
