Unit fuma arambe achirema

Chii chairema arambe achirema? Regai titsanangure zvinhu zvinooneka uwandu.

Ichi ndechimwe chinhu chinokosha chokukomborerwa mafuta, uyewo siyana peturu zvigadzirwa.

Features rokuti

In petrochemical ano shandisa chikwata arambe achirema zvinhu zvakadai makirogiramu / m3, uyewo g / m3. Kushandisa zvakafanana Masvomhu anoitwa tsika chokuita Pakusarudza kurema fuma. Pamberi bhuku, uyewo kuvazivisa arambe achirema zviri pfuma, tinogona huwandu mafuta.

kutsunga

Kurema pfuma kana musanganiswa yakaisvonaka pamashandiro runomirira uwandu vakawanda, izvo zviri mune chikwata vhoriyamu. SI chairema arambe achirema - makirogiramu / m3. Kutora nokuti kukosha mukanyiwa mumwe cubic mita rimwe kwakadonhera mvura, iyo inotorwa panguva tembiricha rworwendo mana.

Kumboda haina compute Mhedziso kukosha nefuma kana vasanganise zvinoriumba, uye hama arambe achirema iyo inotaura nhamba kurema musanganiswa (chikamu) kuti mvura yakachena pamusoro vhoriyamu zvakaenzana.

Maererano kusanganiswa kukosha indekisi hama uye mhedziso arambe achirema ndiwo chete, mune misiyano chete ari divi. Mune hama kusavapo chikwata arambe achirema.

In nyika yedu pane chinokosha GOST 3900, maererano nayo Kutsunga arambe achirema pa tembiricha vanoratidza 20 Celsius.

chaidzo dzemarudzi mitemo inoshandiswa kuverenga arambe achirema mafuta ekisipoti uye peturu zvigadzirwa. Zvinosanganisira kushandisa hydrometer uye digitaalinen arambe achirema analyzer.

MuUnited States uye Britain akashandisa zvimiso tsika dzakadai madhigirii, akasuma kunyange anokosha madhigirii Baume uye IPA. Pakati pavo pane ukama yakaratidzwa svomhu equations.

Mamwe mabhuku zvinhu zvinotaurwa rokuti arambe achirema d204. Chaizvoizvo ichi panyama kwazvo akayera panguva dzakasiyana-siyana tembiricha tsika, achishandisa kukosha coefficient ose volumetric kuwedzera.

Density somunhu yoga chakarurama kunokosha nokuda petrochemical indasitiri. Uyezve, zvinhu izwi rinoshandiswa Pakusarudza STRUCTURAL-boka sezvamunoita nokuongorora musanganiswa yeHydrocarbon zvikamu zviduku.

Kubva chii arambe achirema zvinoenderana

Zvidzidzo arambe achirema kuyerwa zvinoratidza kuti muviri kwazvo chokuita vhoriyamu uye vakawanda. Ndezvipi zvimwe zviratidzo zvinoratidzwa muna arambe achirema Nhau?

On arambe achirema kunokanganisa makemikari yezvakaita constituent zvinhu, fractional akafanana, zviri samolecular uremu pakati vomumatunhu, kuvapo solutes zviri garai zvinhu. Zvichienderana kudzika uye Geological zera kuchinja mune arambe achirema mamwe mafuta. In kemesitiri kushandisa zvakadaro arambe achirema zviumbu zvinhu sezvo g / cm3.

Nzira dzekufambisa Pakusarudza arambe achirema

MuRussia, akashandisa kuona arambe achirema hydrometric uye pycnometric nzira. Musimboti yechipiri yakareba uye nguva unoparadza nzira, rinopa kumusoro chipimo kururama. Its hwaro uremu rinowanikwa achienzanisa vakaongorora Vhoriyamu mafuta kana mafuta nemvura pane vakawanda tembiricha zvakaenzana tsika. Zvinoguma chairema arambe achirema kuti 0,0001 mukati. Pycnometers vari girazi midziyo vane rakavhara pechifukidziro. Volume midziyo vanobvumirwa 1, 5, 25 Rine mamiririta.

Chii chaizvo hydrometric nzira? Pane mwero dzakawanda nayo Murabhoritari nzira yokuziva arambe achirema emura mafuta, mafuta yakachena. The nzira inosanganisira kushandisa girazi hydrometer pa +15 uye +20 Celsius.

A hydrometer mudziyo cylindrical, nechepasi pane kutsigisa igwa. nzvimbo yayo inofanira hayo kuva zvakafanana, ichibata. hydrometers Vazhinji vane lämpömittari. The Chishandiso yakaitwa chaiyo scale, ari chairema arambe achirema iripo. Kuti uvandudze rakarurama tsanangudzo, unogona kushandisa mamwe hydrometers, achishandisa mamwe mapoka akawanda nedanda rechikero.

nzira iyi anosarudza kuti arambe achirema pakati motile yakajeka zvinogadzirisa, vachishandisa masanga repasi meniscus kusvika substrate hydrometer. Kana Detective kuti arambe achirema pamusoro opaque mvura hydrometer chikero ari kuverengwa kusarudza masanga neshamhu repamusoro meniscus.

Ane kwakanaka kunyudza hydrometer, namarudzi kugadzwa, kubva arambe achirema pakati parameters vari dzaona. Kuri kuti anosiyana tembiricha 20 madhigirii, kuti arambe achirema kutsunga rinoitwa panguva dziripo tembiricha chakarurama, ipapo recalculation rinoitwa.

Pakuverenga kuti arambe achirema

Muupenyu hwezuva nezuva, vanhu kazhinji vanoshandisa okufananidza kutaura: "chiedza, sokunge mhepo," "rinorema, kufanana mutobvu". Uye zvinenge hapana asingadi kufunga kuti vane zvazvinoreva.

Kuchikoro Physics kosi zvinopiwa vana Masvomhu, izvo zvakabatanidzwa matatu zvenyama zvakawanda: arambe achirema, vakawanda, vhoriyamu. Somuenzaniso, zvinonzi ndaizvipira ngaaverenge vakawanda yemhangura uye simbi mbariro, une vhoriyamu imwe. Kuti titsungirire rakadai, ndiwo zviratidzo zvakakodzera akadai arambe achirema. The denser simbi, chikuru kuchava uremu kubhawa.

How kuti nokuyerwa mukanyiwa mutobvu zvikamu zvine zviyereso zvakasiyana? First kuziva kukwirira, upamhi, urefu neimwe, dzaona kubva uwandu vakapiwa zviratidzo. Unogona kushandisa mhikuriso zviyereso wakaiswa zviyereso. Kuti tizive arambe achirema zvakakodzera kuwana nhamba vakawanda kuti Vhoriyamu chinhu.

mhedziso

Chii arambe achirema? Izvi muviri kwazvo iyo inechirevo imwe fuma. Inonzi nhamba vakawanda kuti Vhoriyamu fuma. parameter ichi runotaurwa netsamba (všetkých), inokosha chairema yakayerwa mu International SI ndiye makirogiramu / m3. Rinoreva fuma pachayo hakubvi bhuku ripi kana kurema chepakutanga mharidzo. Pamusangano magnification pakati katatu kurema musanganiswa kana akachena fuma, chaizvo nguva sezvo zhinji bhuku vachava kuderera, ukuwo arambe achirema anoramba achitsungirira.
