Me pēhea te huri i te pēhanga o te takirere ki te PSI, BAR me te MPA?

Te tahuritanga o te PSI me te MPA, ko te PSI he waeine pēhanga, e tautuhia ana ko te pauna/inihi tapawhā o Peretānia, 145PSI = 1MPa, ā, ko te PSI i te reo Pākehā e kiia ana ko te Pauna ia inihi tapawhā. Ko P he Pauna, ko S he Tapawhā, ā, ko i he Inihi. Ka taea e koe te tatau i ngā waeine katoa me ngā waeine tūmatanui:1 pae≈14.5PSI, 1PSI = 6.895kpa = 0.06895paeKua taunga a Ūropi me te Hononga o Amerika me ētahi atu whenua ki te whakamahi i te PSI hei waeine.

I Haina, ko te tikanga ka whakaahuahia e mātou te pēhanga o te hau i roto i te "kg" (kaua ko te "pauna"). Ko te waeine tinana ko "KG/CM^2", ā, ko te pēhanga o te kotahi kirokaramu ko te kaha o te kotahi kirokaramu i runga i te kotahi henimita tapawha.

Ko ngā waeine e whakamahia whānuitia ana ki tāwāhi ko "PSI", ā, ko te waeine motuhake ko "LB/In2", arā, "pauna/inihi tapawha". He rite tēnei waeine ki te tapanga pāmahana (F).

Hei tāpiritanga, kei reira anō hoki ngā waeine pēhanga pēnei i te PA (Pascal, kotahi Newton i runga i te mita pūrua kotahi), KPA, MPA, BAR, pou wai mirimita, mirimita mercury me ētahi atu waeine pēhanga.

1 Pae (BAR) = 0.1 MPa (MPA) = 100 Knaka (KPA) = 1.0197 kg/henemita tapawha

1 Pēhanga ā-haurangi paerewa (ATM) = 0.101325 MPa (MPA) = 1.0333 Pae (BAR)

Nā te iti rawa o te rerekētanga o te waeine, ka taea e koe te maumahara ki tēnei:

1 Pae (BAR) = 1 Pēhanga ā-haurangi paerewa (ATM) = 1 kg/henimita tapawhā = 100 kirokaramu (KPA) = 0.1 MPa (MPA)

Ko te huringa o te PSI penei:

1 Pēhanga ā-haurangi paerewa (ATM) = 14.696 pauna/inihi 2 (PSI)

Te whanaungatanga hurihanga pēhanga:

Pēhanga 1 Pae (BAR) = 10^5 Pa (PA) 1 Dadin/cm 2 (dyn/cm2) = 0.1 Pa (PA)

1 Terr = 133.322 Pa (PA) 1 mm Hg (mmHg) = 133.322 Pa (PA)

1 mm te pou wai (mmh2O) = 9.80665 Pa (PA)

1 Pēhanga hauhanga hangarau = 98.0665 kite (KPA)

1 Knipa (KPA) = 0.145 pauna/inihi 2 (PSI) = 0.0102 kg/cm 2 (kgf/cm2) = 0.0098 pēhanga hau (ATM)

1 pauna kaha/inihi 2 (PSI) = 6.895 kenta (KPA) = 0.0703 kg/cm 2 (kg/cm2) = 0.0689 Pae (pae) = 0.068 pēhanga hau (ATM)

1 Te pēhanga ā-tinana o te hau (ATM) = 101.325 Kenpa (KPA) = 14.696 pauna/inihi 2 (PSI) = 1.0333 Pae (BAR)

E rua ngā momongā takirereKo tētahi ko te pūnaha "pēhanga ingoa" e tohuhia ana e Tiamana (tae atu ki tōku whenua) i te pāmahana noa (i Haina he 100 nekehanga, ā, ko Tiamana he 120 nekehanga). Ko tētahi ko te "pūnaha pēhanga pāmahana" e tohuhia ana e te US e tohuhia ana i tētahi pāmahana i tētahi pāmahana.

I roto i te pūnaha pāmahana me te pēhanga i te Hononga o Amerika, haunga te 150LB i runga i te 260 nekehanga, ko ngā taumata kē atu i ngā taumata katoa e ahu mai ana i te 454 nekehanga.

Ko te takirere maitai waro Nama 25, 250-pauna (150PSI = 1MPa) he 260 nekehanga, ā, ko te ahotea whakaaetia he 1MPa, ā, ko te ahotea whakamahi i te pāmahana rūma he nui ake i te 1MPa, tata ki te 2.0MPa.

Nō reira, i te nuinga o te wā, ko te taumata pēhanga ingoa e rite ana ki te paerewa US 150LB ko 2.0MPa, ā, ko te taumata pēhanga ingoa e rite ana ki te 300LB ko 5.0MPa, me ētahi atu.

Nō reira, kāore e taea te whakarerekē i te pēhanga me te taumata pāmahana ingoa e ai ki te tātai whakawhiti pēhanga.
