I-LMEC-11 Ukulinganisa Ulwelo Oluqinileyo – Indlela Yokuwa Kwesiphelo Umfanekiso Ovezweyo

I-LMEC-11 yokulinganisa i-Liquid Viscosity – Indlela ye-Falling Sphere

Inkcazo emfutshane:

I-liquid viscosity coefficient, eyaziwa ngokuba yi-liquid viscosity, yenye yeempawu ezibalulekileyo ze-liquid, enezicelo ezibalulekileyo kubunjineli, iteknoloji yemveliso kunye neyeza. Indlela ye-falling ball ifanelekile kakhulu ekufundiseni uvavanyo kwabafundi bokuqala kunye nabafundi be-sophomore ngenxa yento yayo ebonakalayo ebonakalayo, ingcamango ecacileyo kunye nemisebenzi emininzi yovavanyo kunye nomxholo woqeqesho. Nangona kunjalo, ngenxa yempembelelo ye-stopwatch yesandla, i-parallax kunye nebhola ewela embindini, ukuchaneka kokulinganisa isantya sokuwa akuphezulu kwixesha elidlulileyo. Esi sixhobo asigcini nje ngokugcina umxholo wokusebenza kunye novavanyo lwesixhobo sokuqala sovavanyo, kodwa songeza nomgaqo kunye nendlela yokusebenzisa i-laser photoelectric timer, eyandisa ububanzi bolwazi, iphucula ukuchaneka kokulinganisa, kwaye imele ukuhlaziywa kokufundisa kovavanyo.

Iithegi zeMveliso

Iimbonakalo

1. Sebenzisa ixesha lesango le-photoelectric nge-laser, ixesha lokulinganisa elichanekileyo ngakumbi.
2. Ngesibonisi sokulinganisa indawo yesango le-photoelectric, kunye neqhosha lokuqalisa ukuthintela ukulinganiswa okungafanelekanga.
3. Phucula uyilo lomjelo webhola owela phantsi, umngxuma wangaphakathi ongu-2.9mm, ukujongwa kwebhola ewela phantsi kunokulungiswa kakuhle, ukuze iibhola ezincinci zentsimbi nazo zikwazi
Sika umqadi welaser ngokutyibilikayo, wandise ixesha lokuwa kwaye uphucule ukuchaneka kokulinganisa.

Iimvavanyo
1. Ukufunda indlela yovavanyo yokulinganisa ixesha kunye nesantya sokuhamba kwezinto nge-laser photoelectric sensor.
2. Ukulinganisa i-viscosity coefficient (viscosity) yeoyile kusetyenziswa indlela yebhola ewelayo ngefomula yestokes.
3. Ukuqwalasela iimeko zovavanyo zokulinganisa i-viscosity coefficient yolwelo ngendlela yebhola ewelayo kunye nokwenza izilungiso ukuba kuyimfuneko.
4. Funda ngempembelelo yeedayamitha ezahlukeneyo zeebhola zentsimbi kwinkqubo yokulinganisa kunye neziphumo.
