E hia nga poihau ka taea e te rangoheliumwhakakiia?
Hei tauira, he rango 40Lheliumhau me te pehanga 10MPa
Ko te poihau he 10L, ko te pehanga 1 te hau me te pehanga 0.1Mpa
40*10/(10*0.1)=400 poihau
Te rōrahi o te poihau 2.5 mita te diameter = 3.14 * (2.5 / 2) 2 = 4.90625 mita pūrua = 4906.25 rita
I raro i nga tikanga, ko te 1mol hau he 22.4 rita, no reira ko te tapeke o te 4906.25/22.4=mo te 219mol e hiahiatia ana, no reira me 219mol oheliume hiahiatia ana, no reira 219mol*4g/mol=876g oheliume hiahiatia ana
Kia pehea te roa ka taea e aheliumpoihau whakamutunga?
Kia pehea te roa aheliumka taea te penapena poihau he tata te hononga ki te pāmahana.
Anei tetahi tauira o te 10-inihiheliumpoihau.Ko te tikanga, he 10-inihiheliume 5 haora te roa o te poihau.Ko te tikanga, kaore i te tino mohio te wa pupuri.Mena ko teheliumka mau te poihau i roto i te taiao iti ake o te pāmahana, he roa ake te wa pupuri, penei i te ruma hau, i roto i taua taiao, ka taea te pupuri mo te 7 haora.Ka whakawhirinaki tenei ki te pāmahana.
Me aro nui ki te whakamahi i waho: me karo i te ra i mua i te tiimata o te mahi.Ka kore te poihau e kanapa i muri i te ra o te ra, ara, ka pa te "whakaora" i te pāmahana, me te roanga o te oraheliumkua tino heke te poihau.
Ki te kore e taea e koe te karo tika ra kiheliumpoihau, me aro nui koe ki teheliumpoihau i raro i te ra.Ko te tikanga, ka taea e ratou mo te 4 haora anake.Mena he raumati, he ahua kaha te rama, he uaua ki te pupuri mo te 4 haora.No reira, me aro koe ki te wa tahua i a koe e mahi ana i nga mahi.
