U beddelashada Psi ee MPa, psi waa unug cadaadis ah, oo lagu qeexay rodol halkii inji oo labajibbaaran, 145psi=1MPa, PSI waxa loo yaqaan Pound sper inch oo Ingiriisi ah.P waa rodol, S waa afar gees, anna waxaan ahay inch.U beddelashada dhammaan cutubyada halbeegyada mitirka wax-soo-saarka:
1 bar≈14.5psi;1psi=6.895kPa=0.06895bar
Wadamada sida Yurub iyo Maraykanka ayaa caadaystay inay psi u isticmaalaan unug ahaan
Shiinaha, waxaan guud ahaan ku qeexnaa cadaadiska gaaska ee "kg" (halkii "jin"), unugga jidhkuna waa "kg/cm ^ 2".Hal kiilogaraam oo cadaadis ah macnaheedu waa in hal kiilogaraam oo xoog ahi uu ku dhaqmo hal sentimitir oo laba jibbaaran.
Cutubka inta badan laga isticmaalo dibadda waa “Psi”, unugga gaarka ahna waa “lb/in2”, oo ah “pound halkii inji oo labajibbaaran”.Unuggani waa sida cabbirka heerkulka Fahrenheit (F).
Intaa waxaa dheer, waxaa jira Pa (Pascal, hal Newton wuxuu ku shaqeeyaa hal mitir oo laba jibbaaran), KPa, Mpa, Bar, column biyaha milimitir, milimitir meerkuri iyo unugyo kale oo cadaadis ah.
1 bar (bar) = 0.1 MPa (MPa) = 100 kilopascal (KPa) = 1.0197 kg/cm²
1 cadaadiska atmospheric caadiga ah (ATM) = 0.101325 MPa (MPa) = 1.0333 bar (bar)
Sababtoo ah farqiga u dhexeeya unuggu waa mid aad u yar, waxaad u qori kartaa sidan:
1 bar (bar) = 1 cadaadiska atmospheric caadiga ah (ATM) = 1 kg/cm2 = 100 kilopascals (KPa) = 0.1 megapascals (MPa)
Beddelka psi waa sida soo socota:
1 cadaadiska atmospheric caadiga ah (atm) = 14.696 rodol inch 2 (psi)
Xiriirka beddelka cadaadiska:
Cadaadiska 1 bar (bar) = 10^5 Pa (Pa) 1 dyne/cm2 (dyn/cm2) = 0.1 Pa (Pa)
1 Torr (Torr) = 133.322 Pa (Pa) 1 millimitir oo meerkuri ah (mmHg) = 133.322 Pa (Pa)
1 mm tiirka biyaha (mmH2O) = 9.80665 Pa (Pa)
1 cadaadiska atmospheric injineernimada = 98.0665 kilopascals (kPa)
1 kilopascal (kPa) = 0.145 lbf/in2 (psi) = 0.0102 kgf/cm2 (kgf/cm2) = 0.0098 cadaadiska atmospheric (atm)
1 rodol xoog/inji 2 (psi) = 6.895 kilopascal (kPa) = 0.0703 kiiloogaraam xooga / sentimitir 2 (kg/cm2) = 0.0689 bar (bar) = 0.068 cadaadiska atmospheric (atm)
1 cadaadiska jawiga jirka (atm) = 101.325 kilopascals (kPa) = 14.696 rodol halkii inji 2 (psi) = 1.0333 bar (bar)
Waxaa jira laba nooc oo hababka waalka ah: mid waa nidaamka "cadaadiska magaca ah" ee uu matalayo Jarmalka (oo uu ku jiro waddankayga) oo ku salaysan cadaadiska shaqada ee la ogol yahay ee heerkulka qolka (100 digrii dalkayga iyo 120 darajo ee Jarmalka).Mid waa "nidaamka heerkulka iyo cadaadiska" ee uu matalo Maraykanku oo uu matalo cadaadiska shaqada ee la ogol yahay ee heerkul gaar ah
Nidaamka heerkulka iyo cadaadiska ee Maraykanka, marka laga reebo 150LB, oo ku salaysan 260 darajo, dhammaan heerarka kale waxay ku saleysan yihiin 454 darajo.
Cadaadiska la oggol yahay ee fasalka 150-psi (150psi=1MPa) No. 25 kaarboon birta valve waa 1MPa ee 260 darajo, iyo cadaadiska la oggol yahay ee heerkulka qolka ayaa aad uga weyn 1MPa, qiyaastii 2.0MPa.
Sidaa darteed, guud ahaan marka la hadlo, heerka cadaadiska magaca ee u dhigma heerka Mareykanka ee 150LB waa 2.0MPa, heerka cadaadiska magaca ee u dhigma 300LB waa 5.0MPa, iyo wixii la mid ah.
Sidaa darteed, cadaadiska magaca iyo heerkulka iyo darajooyinka cadaadiska looma beddeli karo si caadi ah iyadoo loo eegayo qaabka beddelka cadaadiska.
Psi ilaa MPa miiska beddelka cadaadiska
Beddelka PSI-MPa
