Muaj pes tsawg lub zais pa tuaj yeem lub tog raj kheej ntawmheliumsau?
Piv txwv li, lub tog raj kheej ntawm 40lheliumroj nrog lub siab ntawm 10MPA
Lub zais pa yog kwv yees li 10L, lub siab yog 1 qhov chaw thiab lub siab yog 0.1mpa
40 * 10 / (10 * 0.1) = 400 zais pa
Lub ntim ntawm lub zais pa nrog txoj kab uas hla ntawm 2.5 meters = 3.14 * (2.5 / 2) 2 = 4.90625 square metres = 4906.25 litres
Nyob rau hauv cov qauv ntawm cov qauv, 1 teev roj yog 22.4 liv, yog li tag nrho ntawm 4906.25 / 22.4 = Txog 219Mol ntawmheliumxav tau, yog li 219mol * 4g / mol / mol = 876g ntawmheliumyog xav tau
Ntev npaum li casheliumzais pa zaum kawg?
Ntev npaum li casheliumCov zais pa tuaj yeem khaws cia yog qhov sib cuam tshuam nrog qhov ntsuas kub.
Ntawm no yog ib qho piv txwv ntawm 10-ntiheliumzais pa. Feem ntau, ib 10-ntiheliumZais Pa tau ntev li 5 teev. Ntawm chav kawm, lub sijhawm uas tuav tau tsis meej. Yog tusheliumCov zais pa tau khaws cia nyob rau hauv ib puag ncig kub tsawg, xws li chav tsev cua txias, nws tuaj yeem khaws cia rau 7 teev. Qhov no nyob ntawm seb qhov kub.
Saib xyuas tshwj xeeb yuav tsum tau them nyiaj rau kev siv sab nraum zoov: Thov zam kev tshav ntuj kom ntau li ntau tau ua ntej pib ua haujlwm. Lub zais pa yuav tsis ci tom qab tshav ntuj, uas yog, "oxidation" cuam tshuam los ntawm qhov kub thiab txias, thiab lub neej ncua ntawm lubheliumCov zais pa tau zoo heev.
Yog tias koj tsis tuaj yeem zam kev tshav ntuj ncaj qha nrogheliumCov pob, koj yuav tsum tau them nyiaj tshwj xeeb rau covheliumCov zais pa nyob rau hauv tshav ntuj. Feem ntau hais lus, lawv muaj peev xwm tsuas yog nyob ntev li 4 teev xwb. Yog tias nws yog lub caij ntuj sov, lub teeb yog qhov muaj zog, thiab nws yog qhov nyuaj rau kev tswj hwm nws rau 4 teev. Yog li, koj yuav tsum tau them sai sai rau lub sijhawm siv nyiaj txiag thaum ua cov haujlwm.
