Cov kauj ruam los nrhiav qhov ntim ntawm cov khoom tsis sib xws
- Ua kom cov khoom tawg mus rau hauv cov duab nws ntim koj paub yuav ua li cas xam (zoo li polygons ,
- cylinders, thiab cone).
- Xam qhov ntim ntawm tus me cov duab .
- Ntxiv tag nrho cov ntim kom tau tag nrho ntim ntawm puab .
Tsis tas li lo lus nug yog, koj yuav pom qhov ntim ntawm lub tsev zoo li cas?
Piv txwv li, rau chav cylindrical, ntsuas qhov deb ntawm cov phab ntsa sab nraud, ces faib los ntawm 2 mus rau nrhiav chav tsev ncig lub voj voog. Square lub vojvoog, muab qhov tshwm sim los ntawm tus lej pi lossis 3.1416, ces muab faib los ntawm chav tsev qhov siab los txiav txim qhov ntim.
Ib tug kuj yuav nug, dab tsi units yog siv los qhia ntim? Chav tsev . Raws li SI system, lub hauv paus chav tsev rau ntsuas qhov ntev yog lub 'meter' thiab ntim Yog li ntsuas hauv cubic meters, qhov twg: 1 m3 = 1 m. 1m ua.
Ib yam li ntawd, qhov ntim ntawm ib yam khoom yog dab tsi?
Ntim yog qhov ntau ntawm peb-dimensional spaceenclosed los ntawm qhov chaw kaw, piv txwv li, qhov chaw uas asubstance (khoom, kua, roj, los yog plasma) los yog cov duab occupies orcontains. Kev tshem tawm ntawm cov kua kuj tuaj yeem siv los txiav txim qhov ntim ib gas.
Tus qauv rau cheeb tsam yog dab tsi?
Thaj chaw yog ntsuas nyob rau hauv square units xws li squareinches, square feet los yog square meters. Yuav nrhiav tau cheeb tsam ntawm arctangle, muab qhov ntev los ntawm qhov dav. Cov qauv yog: A = L * W qhov twg A yog tus cheeb tsam , L yog qhov ntev, W yog qhov dav, thiab * txhais tau tias sib npaug.

Yuav ua li cas koj xam qhov muaj peev xwm poob hauv ib lub voj voog?
Voltage poob: Parallel Circuit Qhov no txhais tau hais tias qhov hluav taws xob poob thoob plaws txhua qhov tsuas yog tag nrho qhov hluav taws xob ntawm lub voj voog muab faib los ntawm tus lej ntawm cov resistors hauv Circuit Court, lossis 24 V / 3 = 8 V
Yuav ua li cas koj xam ntim ntawm qhov ntev?
Chav ntsuas Volume = ntev x dav x qhov siab. Koj tsuas yog yuav tsum paub ib sab kom paub qhov ntim ntawm lub voos xwmfab. Cov ntsuas ntsuas rau ntim yog cubic units. Volume yog nyob rau hauv peb-dimensions. Koj tuaj yeem muab cov sab hauv txhua qhov kev txiav txim. Sab twg koj hu ntev, dav, lossis qhov siab tsis muaj teeb meem
Yuav ua li cas koj pom qhov ntim ntawm ib qho prism sib xyaw?
Thawj cov duab sib xyaw yog kev sib xyaw ua ke ntawm cov duab plaub prism thiab lub pyramid. Txhawm rau nrhiav qhov ntim ntawm tag nrho cov duab koj pom qhov ntim ntawm txhua tus neeg cov duab thiab ntxiv rau lawv ua ke. Qhov thib ob daim duab muaj ib lub tog raj kheej thiab lub hemisphere
Yuav ua li cas koj xam qhov ntim ntawm huab cua ntws?
Los ntawm kev sib npaug ntawm huab cua tshaj tawm los ntawm qhov chaw hla ntu ntawm cov kav dej, koj tuaj yeem txiav txim siab cov huab cua ntim dhau los ntawm qhov taw tes hauv cov kav dej hauv ib chav tsev ntawm lub sijhawm. Volume flow feem ntau ntsuas hauv Cubic Feet per Minute (CFM)
Yuav ua li cas koj pom qhov tsis paub meej ntawm ib qho cuab yeej?
Txhawm rau xam qhov tsis paub meej tus qauv, ib nrab ntu yuav muab faib los ntawm √3. Piv txwv li, ib qho cuab yeej uas muaj kev lees paub los yog qhov tseeb ntawm ± 0.004mm yuav muaj lub sijhawm tag nrho ntawm 0.008mm thiab ib nrab ntawm 0.004. Tus qauv tsis paub meej yuav yog 0.008mm / 2√ 3 lossis 0.004mm / 3, uas yog 0.0023mm
