Kev ntsuas Centrifuge Rotor Radius

Lub Rotor Radius yog cov lub vojvoog ntawm kev sib hloov ntsuas hauv centimeters los yog ntiv tes. Piv txwv li, hauv daim duab hauv qab no - Lub Rotor Radius yog 12.7cm.

Tsis tas li ntawd, G tus nqi hauv centrifuge yog dab tsi?

g = (1.118 × 10-5) R S2 qhov twg g yog tus txheeb ze centrifugal quab yuam, R yog lub vojvoog ntawm lub rotor hauv centimeters, thiab S yog qhov ceev ntawm qhov centrifuge nyob rau hauv revolutions ib feeb. Rau ib txhia centrifuges , muaj lub pob "rpm / rcf" rau kev hloov pauv tsis siv neeg ntawm rpm- tus nqi hauv g.

Tsis tas li ntawd, qhov txawv ntawm RPM RCF thiab G yog dab tsi? RPM stands rau "Revolutions per minute." Qhov no yog li cas cov tuam txhab centrifuge feem ntau piav qhia sai npaum li cas cov centrifuge mus. Lub rotor, tsis hais nws qhov loj npaum li cas, tab tom tig ntawm tus nqi ntawd. RCF (tus txheeb ze centrifugal quab yuam) yog ntsuas hauv quab yuam x lub ntiajteb txawj nqus lossis g - quab yuam.

Yog li ntawd, RCF thiab G yog tib yam?

Kwv tij Centrifugal Force ( RCF ) yog lo lus siv los piav txog tus nqi ntawm lub zog accelerative siv rau ib qho qauv hauv centrifuge. RCF yog ntsuas nyob rau hauv ntau ntawm tus qauv acceleration vim lub ntiajteb txawj nqus ntawm lub ntiaj teb nto (x g). Qhov no yog vim li cas RCF thiab "x g "yog siv sib hloov hauv cov txheej txheem centrifugation.

Kuv yuav xam RPM li cas?

Txhob suav thaum 1 feeb dhau los. Qhov no yog pes tsawg revolutions ib feeb, los yog RPM , cov khoom ua. Tsis txhob txwv qhov suav ntawm 1 feeb, koj tuaj yeem xav suav rau 2 lossis 3 feeb thiab mam li faib cov suav los ntawm cov feeb kom tau txais RPM yog tias qhov khoom tig maj mam.

Yuav ua li cas koj pom lub kaum sab xis nruab nrab muab qhov chaw thiab lub vojvoog ntawm ib lub sector?

Kev txiav txim siab Central Angle Los ntawm Sector Area (πr2) × (central angle in degrees ÷ 360 degrees) = sector area. Yog hais tias lub hauv paus lub kaum sab xis ntsuas nyob rau hauv radians, lub mis hloov mus ua: sector cheeb tsam = r2 × (central kaum hauv radians ÷ 2). (θ ÷ 360 degree) × πr2. (52.3 ÷ 100π) × 360. (52.3 ÷ 314) × 360

Qhov txawv ntawm lub vojvoog thiab lub vojvoog ntawm curvature yog dab tsi?

Radius ntawm curvature yog lub vojvoog ntawm lub voj voog uas kov lub nkhaus ntawm ib qho chaw thiab muaj qhov sib npaug thiab qhov nkhaus ntawm qhov taw tes. Radius yog qhov nrug nruab nrab ntawm qhov chaw thiab lwm qhov taw tes ntawm lub voj voog ntawm lub voj voog lossis qhov chaw ntawm tus kheej. Nyob rau hauv lub voj voog koj yuav tsum siv lub sij hawm radius

Dab tsi yog qhov sib npaug ntawm lub voj voog nrog lub vojvoog ntawm 5?

Cov qauv ntawm lub voj voog yog muab hauv qab no: (x – h) 2 + (y – k) 2 = r2, qhov chaw nyob ntawm (h, k) thiab r yog qhov ntev ntawm lub vojvoog. Hauv qhov no, h yuav yog -3, k yuav yog 6, thiab r yuav yog 5

Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?

Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
