Ukuze ufunde ukuthi bahumushe amalitha uphethiloli ngethani

Namuhla, abaningi abathengi fuel bahlangabetana nebumatima kanye nophethiloli ukudluliswa kusuka amayunithi ivolumu amayunithi esisindo futhi okuphambene nalokho. Ikakhulukazi le ndaba ingaphezu ezimali ukhathazekile bekwi umbono irisidi yayo kanye nokuqaliswa. Ngempela, indlela ukuhumusha amalitha uphethiloli ngethani noma enze ukuguqulwa reverse? Sekuyisikhathi ekugcineni ukubhekana nale nkinga.

Kanjani ukuze uthole amathani amalitha

Uma esikoleni safundiswa ukuthi isisindo noma iyiphi komzimba kuncike kwabantu bayo. Kunjalo ngoba uketshezi. Kukhula kwabantu uphethiloli noma diesel, kuyancipha umthamo yayo. Lobu buhlobo ungaboniswa ifomula elula:

V = M / ρ, lapho ρ - fuel ukuminyana, kg / M3, V - ivolumu kukaphethiloli, uzwakalise ngamalitha, M - fuel ngema kg.

Ngakho, kubonakala sengathi impendulo yombuzo indlela ukuguqula amalitha uphethiloli ngethani, ulula. Ngokuyinhloko udinga ukuthola ukuthi yini kwabantu uhlobo olufanele fuel, bese enze i operation aphansi zezibalo. Nokho, yiso yinkimbinkimbi iqala. Iqiniso lokuthi kwabantu kukaphethiloli - ucezu ezingezwakali futhi akuxhomekile nje kuphela esimweni uhlobo fuel, kodwa futhi lokushisa. Summer, ukushisa incane, futhi inani uphethiloli ukwanda, futhi ebusika, noHezekeli, kwabantu incipha futhi iba amalitha ezincane. Ngakho-ke, ukuze ugweme ukudideka, futhi abantu abanayo edideka phezu indlela ukuguqula amalitha uphethiloli ngethani ngesikhathi esisodwa ke yasungulwa GOST 305-82 for diesel GOST 2084-77 for uphethiloli. Lezi zincwadi ziqukethe amatafula nge lonke ulwazi oluningiliziwe lwezobuchwepheshe uhlobo fuel ngamunye.

Kanjani ukuze uthole amathani amalitha

Ukuze uthole ukuthi yini nesisindo se-ivolumu ikakhulukazi ukusetshenziswa fuel ephambene maqondana: M = V x ρ. Ungakhohlwa ukuthi ngenxa kukhona amakhilogremu etholwe, okusadingeka ukuba zihunyushelwe olimini amathani. Kubonakala sengathi yonke into icacile, kodwa umbuzo uyasala nge futhi ukulethwa kwemibiko ukuze neziphathimandla zokulawula. Isimo sezulu sishintsha njalo, kodwa ngaso sonke isikhathi unake thermometer kanye kancane. Indlela kulokhu?

ukuguqulwa zici

Ukuze translation lula futhi efanele Russian Federation Industry and Amandla Ministry usenqume ukusungula ezihleliwe amanani isilinganiso ukuminyana yohlobo ngalunye lobukhulu nophethiloli. Manje, Accountants kungukuthi agonize phezu indlela ukuguqula amalitha uphethiloli ngethani, futhi umane ukusebenzisa okuza wathola. Ngakho, ngokwesibonelo, uphethiloli grade A-76 (IA-80), kuba elilingana 0,715 g / cm ^3, fuel 92 RON isilinganiso ukuminyana ezithile 0,735 g / cm ³ kuya AI-95 - 0,750 g / cm ³ futhi ekugcineni, isilinganiso nesisindo ezithile AI-98 kuyinto 0,765 g / cm ^3. Njengoba for udizili, ukuze ugcwalise ukudluliswa amathani amalitha noma okuphambene nalokho, kuba sanquma ukuba sisebenzise Coefficient 0,769. Ngesikhathi esifanayo Rostekhnadzor yokuguqula fuel zisebenzisa ukuminyana zabo amagugu. Ngakho, i- LNG kusho Inani lale ipharamitha - 0.6 t / m ^3, futhi ilingana 0,84 udizili. Ngakho isiphetho elula: uma ubika isidingo ukusebenzisa lezo zici, okuyinto kwalandelwa ukugeza igunya labo lokuphatha. It uhlala ukuze ungeze ukuthi langempela ukuminyana ukumeda ngokusebenzisa hydrometers, futhi ngaphezu kwalokho, ungasebenzisa ulwazi olushiwo amanothi maphilisi.
