Te hurihanga o nga waeine pehanga hau

Ko te pehanga hau te pehanga o te pakitara tuku hau, koinei te whakaaturanga macroscopic o te maha o nga ngota ngota e pa tonu ana ki te pakitara, he tawhā nui hei whakaahua i te ahua o te punaha. He maha nga ahuatanga o te tinana me te matū, penei i te ira, te ira koropupu, te pehanga kohu, ka tata katoa ki te pehanga. He mea nui ano te pehanga i roto i te ako o te whakamaarama matū me te whakanekeneke matū. No reira, he mea nui te ine o te pehanga.

Ko nga waeine e whakamahia nuitia ana ko: pae (pa), pascal (Pa). Ko te waeine pēhanga, i roto i te ahupūngao, e pā ana ki te tōpana e mahi poutū ana i runga i te mata o tētahi mea. Ko te waahanga ko Pascal (whakapotohia ko Pa Ko te reta ko “Pa”). (Ko te tikanga, ko Newton N te waeine o te pehanga.) Ko te waeine o te pehanga ko Pascal, he tikanga ki te karanga pehanga pehanga i roto i te oranga) I Haina, ko te tikanga ka whakaahuahia te pehanga o te hau he "kilogram" (ehara i te "jin. ”), ko te wae “kg•f/cm2″, he kirokaramu te pehanga he kirokaramu topana e mahi ana ki te henemita tapawha.

1Paerewa pehanga hau = 760mmHg = 76cmHg = 1.01325×105Pa=10.336m pou wai. 1 paerewa te pehanga hau

= 101325 N/㎡. (I te nuinga o te wa 1 te hauwaarangi paerewa = 1.01×105Pa i roto i nga tatauranga)

Mena kei te pirangi koe ki te mahi tatau tika, ko te hononga e whai ake nei:

Te hononga hurihanga pehanga:

1 dyne mo ia henimita tapawha (dyn/cm2) = 0.1 Pa (Pa)

1 torr = 133.322 Pa

1 mirimita mercury (mmHg) = 133.322 Pa (Pa)

1 mm pou wai (mmH2O) = 9.80665 Pa (Pa)

1 te pēhanga kōhauhau = 98.0665 kilopascals (kPa)

1 kilopascal (kPa) = 0.145 pauna topa mo ia inihi tapawha (psi) = 0.0102 kirokaramu topa mo ia henimita tapawha (kgf/cm2) = 0.0098 atm (atm)

1 pauna kaha mo ia inihi tapawha (psi) = 6.895 kiropascals (kPa) = 0.0703 kirokaramu toia mo ia henimita tapawha (kgf/cm2) = 0.0689 pae (pa) = 0.068 atm (atm)

1 Te pehanga hau-a-tinana (atm) = 101.325 kiropascals (kPa) = 14.695949400392 pauna kaha mo ia inihi tapawha (psi) = 1.01325 pae (pa)
