Te Whakamārama mō te PSI me te PSIG: Ngā Wāhanga Pēhanga, Ngā Rerekētanga, me ngā Huringa
He aha te PSI?
Ka ine te PSI (Pauna ia Inihi Tapawhā) i te pēhanga mā te tatau i te kaha (pauna) e pā ana ki te kotahi inihi tapawhā o te horahanga. E whakamahia whānuitia ana i roto i ngā pūnaha waipēhi, te pēhanga potae, me ngā taputapu ahumahi, koinei te waeine pēhanga emepaea paerewa.
Kia mōhio: Tērā pea ka pā te PSI ki te pūtea (Initial Coin Offering) me te rongoā (Postpartum Stress Inventory), engari e arotahi ana tēnei aratohu ki ngā horopaki hangarau.
PSI hei Wāhanga Pēhanga
Whakamāramatanga
Ka ine te PSI i te pēhanga ina pā te 1 pauna o te kaha ki runga i te mata 1 inihi². He mea nui i te US/UK mō ngā tono hangarau.
Ngā Tahuritanga Matua
| PSI | kPa | pae | MPa |
|---|---|---|---|
| 1 PSI | 6.895 | 0.0689 | 0.00689 |
| 1 atm | 101.3 | 1.013 | 0.1013 |
| Ngā ōrite | 1 atm ≈ 14.696 PSI | 1 MPa ≈ 145 PSI |

-HeTakirere Pōro WOG 2000Ko tōna tikanga he 2000 PSI te takirere pōro = 137.9 pae, 13.79 MPa rānei
He aha te PSIG?
Whakamāramatanga PSIG
Ka ine te PSIG (Pounds per Square Inch Gauge) i te pēhanga ine—pēhangae pā ana ki te pēhanga o te hauKoinei te uara e whakaaturia ana i te nuinga o ngā ine pēhanga.
PSI me PSIG: Ngā Rerekētanga Matua
| Wā | Momo | Pūwāhi Tohutoro | Tātai |
|---|---|---|---|
| PSI | I runga i te horopaki | Ka rerekē (he maha ngā wā = PSIG) | Wāhanga whānui |
| PSIG | Te pēhanga ine | Te pēhanga ā-rohe | PSIG = PSIA – 14.7 |
| PSIA | Pēhanga tino | Korekore rawa | PSIA = PSIG + 14.7 |
Ngā Tauira Whaihua
He potae kua tohua ko "35 PSI" = 35 PSIG (pēhanga ine).
Ko te pānui a te korehau i te taumata moana he -14.7 PSIG (PSIA = 0).
PSI vs PSIG: Ngā Whakamahinga Matua
Ngā Whakamahinga Ahumahi
PSIG:Whakamahia i roto i ngā ine pēhanga, ngā pūwhakakoi, me ngā pūnaha waipēhi (hei tauira, te ine i te pēhanga o ngā potae, te pēhanga o ngā paipa rānei).
PSIA:He mea nui i roto i ngā pūnaha rererangi/korehau ina he mea nui te pēhanga tino.
Ngā Whakamārama Hangarau
He maha ngā tuhinga e whakarapopoto ana i te PSIG hei “PSI,”engari me wehewehe ngā horopaki tino pakari (Hei tauira, ko ngā whakaritenga rererangi e whakarārangi ana i te "18 PSI" engari ko te tikanga he 18 PSIG).
Ture matua:Ko te nuinga o ngā pānui "PSI" ā-ahumahi he PSIG.
Ngā Ripanga Tahuritanga PSI Whānui
Ngā Huringa Wāhanga Pēhanga
| Wāhanga | PSI | pae | MPa |
|---|---|---|---|
| 1 PSI | 1 | 0.0689 | 0.00689 |
| 1 pae | 14.5 | 1 | 0.1 |
| 1 MPa | 145 | 10 | 1 |
Ētahi atu Tahuritanga Matua
1 PSI = 0.0703 kg/cm²
1 kg/cm² = 14.21 PSI
1 atm = 14.696 PSI = 101.3 kPa = 760 mmHg
Ngā Pātai Auau: PSI me PSIG
P: He rite tonu te PSI ki te PSIG?
A: I roto i te mahi, ko te kupu "PSI" he tohu i te PSIG (te pēhanga ine). I te taha hangarau, he koretake te PSI, engari ko te PSIGmāramangā tohutoro ki te pēhanga o te hau.
P: He aha i whakamahia ai e ngā takirere ngā whakatauranga PSI?
A: Ko te PSI e tohu ana i te manawanui pēhanga mōrahi (*hei tauira, 1000 PSI takirere = 68.95 pae*).
P: Āhea ahau me whakamahi i te PSIA me te PSIG?
A: Whakamahia te PSIG mō ngā pānui pēhanga o ngā taputapu; te PSIA mō ngā pūnaha korehau, ngā tātaitanga pūtaiao rānei.
Ngā Whakaaro Matua
1. PSI = te kaha mō ia inihi tapawha; PSIG = PSI e pā ana ki te pēhanga o te hau.
2. Ko te nuinga o ngā uara "PSI" ā-ahumahi he PSIG (hei tauira, te pēhanga o te potae, ngā whakatauranga takirere).
3. Ngā tahuritanga matua: 1 PSI = 0.0689 pae, 1 MPa = 145 PSI.
