Indlela ukufumana okuninzi?

Abaninzi kuthi ngexesha lesikolo bazibuza: "Indlela yokufumana ubunzima bomzimba"? Ngoku siza kuzama ukuba uphendule lo mbuzo.

Ukufumana ubunzima ngenxa umthamo wayo

Masithi, onawo kukho ezimakhulu mabini iilitha umphanda. Uza ukugcwalisa ngokupheleleyo oko amafutha emoto ayekwi oyisebenzisayo ukufudumeza kwibhoyila yabo. Indlela yokufumana ezininzi casks ezaliswe diesel? Makhe ukuzama ukusombulula le ngxaki kunye nani elula xa efika kuqala.

Ukusombulula le ngxaki, ukuze ukufumana indlela eninzi izinto ngokusebenzisa umthamo wayo kakhulu lula. Ukuze le fomyula ukusebenzisa iziyobisi womxhuzulane ethile

p = m / V,

apho p kokona kuxinana ngqo ukwimo;

m - ubunzima baso;

v - ithatha umthamo.

Njengoko umlinganiselo sobunzima iza kusetyenziswa grams, eekhilogram kunye neetoni. amanyathelo volume: iisentimitha lwezindlu, decimeters kunye neemitha. bekukubi ngqo ibalwa kg / dm³, kg / m³, g / cm³, t / m³.

Ngenxa yoko, ngokungqinelana nemiqathango ingxaki, sifumana i Umphanda neelitha ezimakhulu mabini umthamo. Oku kuthetha ukuba ilingane umthamo m³-2.

Kodwa ufuna ukufunda ukufumana indlela lukhulu. Ukusuka formula ngasentla kubhaliwe eshicilelweyo:

m = p * v

Okokuqala, kufuneka afumane ixabiso r - ezithile lexinene ku diesel. Fumana le Ixabiso lingaba usebenzisa weefayili.

Kule ncwadi, sifumanisa ukuba p = 860,0 kg / m³.

Emva koko wafumana amanani ifomula:

m = 860 * 2 = 1720,0 (kg)

Ngoko ke, impendulo yombuzo yokufumana indlela ubunzima wafunyanwa. Omnye ngetoni kunye neekhilogram asixhenxe anamanci mabini - kukho ubunzima ezimakhulu mabini iilitha diesel zasehlotyeni. Ngoko ungenza nje ukwenza ubalo rough ubunzima zizonke umphanda kunye yokubeka amandla Umphanda nge solarium.

Ukufumana ubunzima ngenxa lexinene nomthamo

rhoqo kwimisebenzi eyenziwayo inokufumaneka izixa Physics ezifana ubunzima, lexinene umthamo. Ukuze ukusombulula ingxaki yokufumana njani ubunzima, kufuneka ukwazi umthamo wayo kunye mninzi.

Izinto eziya kufuneka ube:

1) okuphumelela.

2) Calculator (PC).

3) umthamo kumlinganiselo.

4) line.

Yinto eyaziwayo ukuba izinto kunye umthamo ofanayo kodwa ezenziwe ngezinto ezahlukeneyo, ubunzima uya kuba ezahlukeneyo (umz, isinyithi, kunye neenkuni). Ubunzima imizimba, ezenziwe ngento ethile (ngaphandle imigodi), ezi kisekiyo ngqo umthamo zifundo ngayo. Kungenjalo, njalo - umlinganiselo lwezinto ubunzima-to-umthamo. Eli nani ubizwa ngokuba 'lexinene nto. " Siza kuthi zibonakaliswe yileta d.

Ngoku, ingxaki ekufuneka isonjululwe ukufumana indlela ubunzima ngokungqinelana kunye nefomula d = m / V, apho

m ubunzima isifundo (kg)

V umthamo wayo (in cubic metres).

Ngenxa yoko, lexinene into ke grammage somxholo kwayo.

Ukuba ufuna ukufumana lexinene umbandela yento wadala apho, kufuneka usebenzise itafile loxinano, leyo inokufunyanwa zezifundo ezisemgangathweni physics.

Umthamo into ebalwa formula V = h * S, apho

V - volume (m³)

H - ukuphakama injongosenzi (m),

S - indawo isiseko subject (m²).

Xa kunjalo, ukuba unako ngokuchanileyo ukuba umlinganiselo parameters zejiyometri emzimbeni, ngoko ke kufuneka ukubhenela usebenzisa umgaqo Archimedes '. Ukuze wenze oku kufuneka inqanawa ukuba unalo isikali esetyenziselwa ukulinganisa umthamo ulwelo uwise into emanzini, oko kukuthi, ngesitya apho kukho iyantlukwano. Loo ncwadi, apho imixholo isitya, ngumthamo we umzimba iya kwandiswa, nto leyo egxile kuyo.

Ukwazi V umthamo kwanokuxinana na into d, unako lula ukufumana ubunzima yayo iyenze m olungumgubo = d * V. Phambi kokuba ukubala ubunzima efunekayo ukuze zonke iiyunithi zokulinganisela kwinkqubo enye, umzekelo, kwinkqubo SI yinkqubo womlinganiselo ngamazwe.

Ukungqinelana iifomyula ngasentla siyakwazi ukubona oku kulandelayo: ngokuba ukufumana ixabiso olifunayo ezinobunzima eyaziwa kunye nomthamo mninzi eyaziwa kufuneka zande lexinene umbandela umzimba wenziwa kuzo, xa umthamo wawo umzimba.
