Koj paub ntau npaum li cas txog qhov viscosity ntawm cov khoom lag luam nplaum?
Cov khoom lag luam nplaum nplaum: cov ntaub nplaum nplaum, cov ntaub nplaum nplaum, ntawv nplaum yob, ntawv nplaum, lawv ua hom viscosity txhais tau li cas?
Dab tsi yog tus nplaum lo dag zog (G / 25mm) hauv ntawv nplaum yob txhais tau?
Lub ntsiab lus ntawm kev nplaum muaj zog (G / 25mm): Nws qhia txog tus naj npawb ntawm grams (g) ntawm ib qho khoom uas tuaj yeem txhawb nqa ib qho 25mm ntev.
Ntsuas cov tev quab yuam ntawm kua nplaum. Yuav ua li cas muaj pes tsawg grams yuav tsum tau rub sib cais ib tug 25 hli dav sawb? Kev hloov dua siab tshiab yog raws li hauv qab no:
1n/1cm {{=0. 102kg / 25cm {} g / 25cm {} g /}}. 2/2 hli
1n/1mm {{=0. 102kg / 25mm {5}} g / 25mm
Cov sawv cev yog sib txawv me ntsis nyob rau hauv cov tuam txhab sib txawv. "Gf / 25mm" thiab "G / 25mm" yog tib yam, thiab tsis muaj qhov sib txawv. F txhais tau tias kev quab yuam, yuam. Nws yog tib yam li G / 25mm, tab sis tsis muaj lub cim ntawm kev quab yuam.
GF yog gram quab yuam, uas yog, lub ntiajteb txawj nqus ntawm 1g khoom. Raws li ib txwm muaj xwm txheej, peb siv Kgf, uas yog, quab yuam kilogram, rau kev suav. 1kgf yog txog 9.80665n.
Newton, sau cov cim Newton, nrog lub cim N, yog ib chav tsev thoob ntiaj teb rau kev ntsuas qhov tseem ceeb ntawm kev quab yuam.
Raws li Newton txoj cai thib ob F {0}} ma, nws tuaj yeem paub tias 1n {2}} kg ·. 1
Qhov ntau ntawm lub zog uas yuav tsum tau ua rau ib qho khoom ntawm ib phaus ntawm ib phaus loj tau txais kev nrawm ntawm 1m / S² txhais tau tias yog 1 Newton.
Hauv physics, g {{= mg yog siv los suav lub nqus nqus, qhov twg g yog qhov loj, thiab g yog tas li, txog 9.8n / kg.
Qhov saum toj no yog lub ntsiab lus ntawm cov nplaum ntawm cov ntawv nplaum yob. Yog koj muaj lus nug, thov hu rau peb, Kunshan Xinchen Electronic Khoom Co., Ltd.
