Kuti mudziwe kumasulira malita a mafuta pa tani

Masiku ano, ambiri mafuta ogula zambiri amavutika ndi mafuta kutengerapo ku mayunitsi voliyumu mu mayunitsi kulemera ndi mosemphanitsa. Makamaka funso limeneli zachuma nkhawa zikugwira view chiphaso ndi kukhazikitsa. Ndithudi, kumasulira malita a mafuta pa tani kapena kuchita kutembenuka n'zosiyana? Ndi nthawi potsiriza kuthana ndi vutoli.

Momwe matani malita

Kamodzi sukulu tinaphunzira kuti kulemera kwa aliyense wa thupi zimadalira kachulukidwe ake. N'chimodzimodzinso kwa madzi. Kwakukulu osalimba a mafuta kapena dizilo, chindichepere adzakhala buku ake. ubwenzi tingasonyezere chilinganizo losavuta:

V = M / ρ, kumene ρ - mafuta osalimba, kg / M3, V - voliyumu ya mafuta, m'kukoma malita, M - mafuta misa mu kg.

Choncho, zikuoneka kuti yankho la funso mmene kutembenuza malita a mafuta pa tani, ndi wosavuta. Choyamba muyenera kupeza zomwe ndi osalimba yoyenera ya mafuta, kenako kuchita ndi pulayimale ntchito masamu. Komabe, ndendende zovuta wayamba. Popeza kuti kachulukidwe wa mafuta - chidutswa capricious ndi zimatengera osati mtundu wa mafuta, komanso kutentha. Chilimwe, kutentha ndi zochepa, ndipo kuchuluka kwa ukuwonjezeka mafuta, ndiponso m'nyengo yozizira, mosemphanitsa, osalimba amachepetsa ndipo malita ang'onoang'ono. Choncho, pofuna kupewa chisokonezo, anthu alibe wodabwa mmene kutembenuza malita a mafuta pa tani pa nthawi imodzi anayamba kupanga ndi GOST 305-82 kwa dizilo ndi GOST 2084-77 kwa mafuta. Mapale muli matebulo ndi mudziwe onse luso pa mtundu uliwonse wa mafuta.

Momwe matani malita

Kuti tipeze chimene ndi unyinji wa buku makamaka ntchito mafuta osiyanitsidwa ubale: M = V × ρ. Musaiwale kuti chifukwa ali makilogalamu analandira amene ayenera kumasuliridwa mu matani. Zikuoneka kuti chirichonse chiri bwino, koma funso n'lakuti ndi kuzipeleka kwa malipoti ku boma zolimbana. Weather amasintha pafupipafupi, koma nthawi zonse diso pa thermometer kamodzi mopepuka. Kodi kukhala mu nkhani iyi?

zinthu kutembenuka

Ntchito yomasulira zosavuta ndi lolondola la Russian Federation Makampani ndi Mphamvu Utumiki waganiza kukhazikitsa atathana mfundo avareji osalimba pa mtundu mafuta. Tsopano, nkhaniyi si kwambiri zimene mmene kutembenuza malita a mafuta pa tani, ndi chabe ntchito koefishienti analandira. Choncho, mwachitsanzo, kuti mafuta kalasi A-76 (IA 80), ndi wofanana 0,715 g / masentimita ^3, mafuta kachulukidwe 92 Ron pafupifupi enieni 0,735 g / masentimita ³ AI-95 - 0,750 g / masentimita ³ ndi Pamapeto pake, pafupifupi yeniyeni kulemera kwa a AI-98 ndi 0,765 g / masentimita ^3. Koma dizilo, kuti amalize kulanda matani malita kapena mosinthanitsa, izo anaganiza ntchito koyefishienti wa 0,769. Pa nthawi yomweyo Rostekhnadzor kwa akatembenuka mafuta ntchito kachulukidwe awo amaika mfundo. Choncho, Lng zikutanthauza mtengo wa chizindikiro ichi - 0,6 T / mamita ^3, ndipo ndi wofanana 0,84 dizilo. Ndizoonekeratu mapeto losavuta: pamene malipoti kufunika kogwiritsa ntchito zinthu zimenezo zimene akutsatiridwa ndi kutenga ulamuliro awo supervisory. Mpaka kuwonjezera kuti leni kachulukidwe muyeso ntchito hydrometers, ndi kuwonjezera, mungathe kugwiritsa ntchito mfundo mwachindunji mu zolemba KATUNDU.
