CBM sawv rau "cubic meter" lossis cubic meter. Cov ntawv luv hauv txoj hauv kev no, qhov ntsuas no feem ntau yog hais txog tag nrho cov cubic meters uas yuav tsum tau ntim thiab xa ib pob. Txoj hauv kev yooj yim los suav qhov CBM lossis qhov cub sib txawv, nyob ntawm daim ntawv pob.
Kauj ruam
Txoj Kev 1 ntawm 4: Xeem Rectangular Block CBM
Kauj Ruam 1. Ntsuas txhua sab ntawm daim duab los qhia
Koj yuav tsum paub qhov ntev, dav, thiab qhov siab ntawm daim duab duab plaub. Siv tus pas ntsuas los nrhiav qhov ntev ntawm txhua sab thiab sau txhua tus nqi.
- CBM yog ntsuas qhov ntim. Yog li, siv cov txheej txheem ntim rau cov duab plaub fab.
- Piv txwv: Xam CBM ntawm cov pob plaub fab uas ntev 15 cm, dav 10 cm, thiab qhov siab 8 cm.
Kauj Ruam 2. Yog tias tsim nyog, hloov qhov loj me mus rau meters
Rau pob me me, peb pom zoo kom siv centimeters, ntiv tes, lossis ko taw. Ua ntej xam CBM, hloov txhua qhov ntsuas kom nws sib npaug tus nqi hauv meters.
- Cov mis hloov pauv pes tsawg sib txawv, nyob ntawm cov koog siv hauv qhov ntsuas thawj zaug.
-
Piv txwv: Yog tias qhov ntsuas thawj zaug yog hauv centimeters, kom hloov mus rau meters, faib cov lej los ntawm qhov hloov pauv ntawm 100. Rov ua cov txheej txheem no rau tag nrho peb qhov kev ntsuas. Chav nyob rau qhov ntev, dav thiab qhov siab yuav tsum zoo ib yam.
- Ntev: 15 cm / 100 = 0.15 m
- Dav: 10 cm / 100 = 0.1 m
- Qhov siab: 8 cm / 100 = 0.08 m
Kauj Ruam 3. Muab qhov ntev, dav, thiab qhov siab
Raws li cov qauv rau kev suav CBM, muab qhov ntev, dav, thiab qhov siab ntawm cov duab plaub.
-
Yog tias sau hauv daim ntawv luv, cov qauv siv yuav zoo li no: CBM = P * L * T
Qhov twg P = ntev, L = dav, thiab T = qhov siab
- Piv txwv: CBM = 0.15 m * 0.1 m * 0.08 m = 0.0012 cubic meter
Kauj Ruam 4. Sau tus nqi CBM
Cov khoom ntawm thawj peb qhov ntev yuav yog ntim thiab CBM ntawm ib pob.
Piv txwv: Pob ntawv CBM yog 0.0012, qhia tias pob khoom no yuav siv li 0.0012 cubic meters ntawm qhov chaw
Txoj Kev 2 ntawm 4: Xeem Lub Tog Raj Kheej CBM
Kauj Ruam 1. Ntsuas qhov ntev thiab lub vojvoog ntawm daim duab los qhia
Thaum cuam tshuam nrog lwm cov tubular lossis lub tog raj kheej, koj yuav tsum paub qhov siab lossis ntev ntawm lub tog raj kheej, nrog rau lub vojvoog ntawm sab ncig. Txiav txim siab qhov ntau thiab tsawg no siv tus pas ntsuas, tom qab ntawd nco ntsoov tus nqi ntawm txhua tus.
- Txij li thaum CBM yog qhov ntsuas ntawm ntim, siv tus qauv lub tog raj kheej ntim mis kom xam CBM ntawm pob cylindrical.
- Daim ntawv ceeb toom tias lub vojvoog ntawm lub vojvoog sab yog ib nrab ntawm txoj kab uas hla, thiab txoj kab uas hla yog qhov deb ntawm ib sab ntawm lub voj voog mus rau lwm qhov. Txhawm rau ntsuas lub vojvoog, ntsuas txoj kab uas hla ntawm lub voj voog nto thiab faib ua ob.
-
Piv txwv: Xam CBM ntawm lub pob cylindrical nrog qhov siab ntawm 64 ntiv tes thiab txoj kab uas hla ntawm 20 ntiv tes.
Txiav txim siab lub vojvoog ntawm pob khoom no los ntawm kev faib txoj kab uas hla ob: 20 ntiv tes / 2 = 10 ntiv tes
Kauj Ruam 2. Yog ua tau, hloov qhov ntsuas no mus rau qhov ntsuas
Rau pob me me, siv centimeters, ntiv tes, lossis ko taw. Hloov qhov ntsuas mus rau tus nqi sib npaug hauv meters ua ntej xam cov cubic meters.
- Qhov hloov pauv hloov pauv yuav siv yog nyob ntawm thawj chav ntsuas.
-
Piv txwv: Yog tias qhov ntsuas thawj zaug yog nyob rau hauv nti, kom hloov mus rau meters, faib cov ntiv tes los ntawm qhov hloov pauv ntawm 39, 37. Rov ua cov txheej txheem no rau ob qhov ntau thiab tsawg.
- Qhov siab: 64 ntiv tes / 39.37 = 1.63 m
- Radius: 10 nti / 39.37 = 0.25 m
Kauj Ruam 3. Ntsuas tus nqi rau cov mis ntim
Txhawm rau nrhiav qhov ntim thiab CBM ntawm lub tog raj kheej, muab lub tog raj kheej qhov siab los ntawm nws lub vojvoog. Tom qab ntawd muab cov txiaj ntsig ntawm ob qhov txiaj ntsig no los ntawm qhov tas mus li pi.
-
Yog tias sau hauv daim ntawv luv, cov qauv siv yuav zoo li no: CBM = H * R2 *
Qhov twg H = qhov siab, R = radius, thiab = tas li pi 3, 14
- Piv txwv: CBM = 1.63 m * (0.25 m)2 * 3.14 = 1.63 m * 0.0625 m2 * 3.14 = 0.32 cubic meters
Kauj Ruam 4. Sau tus nqi CBM
Qhov txiaj ntsig ntawm kev suav hauv cov kauj ruam saum toj no yog ntim thiab CBM ntawm ib pob cylindrical.
Piv txwv: Pob CBM yog 0.32; txhais tau tias pob khoom no siv 0.32 cubic meters ntawm qhov chaw
Txoj Kev 3 ntawm 4: Xam Tus Qauv Tsis Zoo CBM
Kauj Ruam 1. Ntsuas qhov nrug deb tshaj plaws
Txhawm rau xam CBM ntawm pob khoom tsis xwm yeem, koj yuav tsum kho lub pob zoo li lub pob zeb thaiv lub pob. Txawm li cas los xij, txij li tsis muaj qhov ntev sib xws, dav, thiab qhov siab, koj yuav tsum txheeb xyuas qhov ntev, dav tshaj plaws, thiab ntu siab tshaj plaws ntawm pob thiab ntsuas qhov siab tshaj plaws nrug nrog tus kav. Sau txhua qhov ntawm peb qhov kev ntsuas no.
- Txawm hais tias CBM yog ntsuas qhov ntim, tsis muaj tus qauv siv los ntsuas qhov ntim ntawm cov khoom peb-seem tsis xwm yeem. Hloov chaw ntawm kev nrhiav qhov tseeb ntim, koj tsuas tuaj yeem suav qhov ntim kwv yees.
- Piv txwv: Xam CBM ntawm pob khoom tsis xwm yeem nrog qhov siab tshaj plaws ntawm 5 taw, qhov dav tshaj plaws ntawm 3 taw, thiab qhov siab tshaj ntawm 4 taw.
Kauj Ruam 2. Yog tias tsim nyog, hloov qhov loj me mus rau meters
Yog tias koj yuam kev ntsuas qhov ntev, qhov siab, thiab dav hauv centimeters, ntiv tes, lossis ko taw, koj yuav tsum hloov lawv mus rau meters ua ntej xam cov cubic meters ntawm pob.
- Nco ntsoov tias qhov hloov pauv yuav txawv nyob ntawm cov chav uas siv rau kev ntsuas thawj zaug ntawm peb sab ntawm pob.
-
Piv txwv: Yog qhov ntsuas thawj zaug hauv qhov piv txwv no yog hauv ko taw, txhawm rau hloov pauv mus rau meters, faib tus lej ntawm taw los ntawm kev hloov pauv ntawm 3.2808. Rov ua cov txheej txheem no rau tag nrho peb qhov kev ntsuas.
- Ntev: 5 ft / 3.2808 = 1.52 m
- Dav: 3 ft / 3.2808 = 0.91 m
- Qhov siab: 4 ft / 3.2808 = 1.22 m
Kauj Ruam 3. Muab qhov ntev, dav, thiab qhov siab
Kho lub pob zoo li nws yog lub duab plaub thiab muab qhov ntev, dav, thiab qhov siab qhov tseem ceeb ntawm qhov khoom.
-
Yog tias sau hauv daim ntawv luv, cov qauv siv yuav zoo li no: CBM = P * L * T
Qhov twg P = ntev, L = dav, thiab T = qhov siab
- Piv txwv: CBM = 1.52 m * 0.91 m * 1.22 m = 1.69 cubic meters
Kauj Ruam 4. Sau tus nqi CBM
Tom qab nrhiav pom qhov tshwm sim ntawm qhov siab tshaj plaws, koj yuav paub qhov ntim thiab CBM ntawm pob ntawv tsis xwm yeem no.
Piv txwv: Tus nqi kwv yees CBM rau pob yog 1.69. Txawm hais tias nws tsis siv tag nrho qhov chaw, nws yuav xav tau 1.69 cubic meters ntawm qhov chaw ntim khoom thiab thauj khoom
Txoj Kev 4 ntawm 4: Xam Tag Nrho Kev Xa Khoom CBM
Kauj Ruam 1. Tshawb CBM rau txhua pawg pob
Yog tias cov zaub mov xa tuaj muaj ntau pawg, thiab txhua pawg muaj cov pob khoom ntawm qhov loj me, koj tuaj yeem suav tag nrho CBM yam tsis suav CBM ntawm txhua lub thawv. Koj yuav tsum xub nrhiav tus qauv txheem CBM tus nqi hauv txhua pawg.
- Siv ib qho kev xav tau ntawm CBM raws li lub pob ntawm lub pob (duab plaub, lub tog raj kheej, lossis tsis xwm yeem).
- Piv txwv: Cov kab plaub fab, lub tog raj kheej, thiab cov pob tsis xws luag tau piav qhia hauv ntu dhau los ntawm kab lus no yog txhua qhov xa hauv ib qho khoom xa tuaj. Ntawd yog, chav tsev CBM rau cov pob khoom hauv kab yog 0.0012 m3, Chav tsev CBM rau lub tog raj kheej pob khoom yog 0.32 m3, thiab chav tsev CBM rau pawg tsis sib xws yog 1.69 m3.
Kauj Ruam 2. Sib npaug txhua chav CBM los ntawm cov pob ntawv
Hauv txhua pawg, muab chav CBM sib npaug koj suav los ntawm cov pob khoom hauv pawg ntawd. Rov ua cov txheej txheem no kom txog thaum koj ua tiav suav txhua qeb hauv kev xa ntawv.
-
Piv txwv: Muaj 50 pob ib pob ib pob, 35 lub tog raj kheej pob khoom, thiab 8 pob khoom tsis xwm yeem.
- Qeb plaub fab CBM: 0.0012 m3 * 50 = 0.06 m3
- Lub tog raj kheej qeb CBM: 0.32 m3 * 35 = 11.2 hli3
- Qeb tsis xws luag CBM: 1.69 m3 * 8 = 13.52m3
Kauj Ruam 3. Ntxiv txhua pawg CBM
Tom qab suav tag nrho CBM rau txhua pawg hauv kev xa khoom ib zaug, koj yuav tsum tau ntxiv peb qhov tag nrho los nrhiav tag nrho CBM rau kev xa khoom ntawd.
Piv txwv: CBM tag nrho = 0.06 m3 + 11. 2 m3 + 13,52 m3 Luas = 24,78 m3
Kauj Ruam 4. Sau tag nrho CBM rau koj cov zaub mov xa tuaj
Txheeb xyuas koj txoj haujlwm. Txog lub sijhawm no, koj yuav tsum paub tias tag nrho CBM yog dab tsi rau tag nrho cov khoom xa tuaj. Tsis xav tau laij lej ntxiv.
