Sidee loo beddelaa cadaadiska waalka PSI, BAR iyo MPA?

Beddelka PSI iyo MPA, PSI waa cutub cadaadis ah, oo lagu qeexay pound/inch laba jibbaaran oo Ingiriis ah, 145PSI = 1MPa, Ingiriisiga PSI waxaa loo yaqaan pounds halkii laba jibbaaran ee gudaha. P waa pound, S waa square, i waa inch. Waxaad xisaabin kartaa dhammaan cutubyada leh cutubyada dadweynaha:1 bar≈14.5PSI, 1PSI = 6.895kpa = 0.06895barYurub iyo Mareykanka iyo dalal kale ayaa loo isticmaalaa isticmaalka PSI halbeeg ahaan.

Shiinaha, guud ahaan waxaan ku qeexnaa cadaadiska gaaska "kg" (halkii laga isticmaali lahaa "pound"). Cutubka jirku waa "KG/CM^2″, cadaadiska hal kiilogaraamna waa xoogga hal kiilogaraam ee hal sentimitir oo laba jibbaaran.

Cutubyada inta badan loo isticmaalo dibadda waa "PSI", cutubka gaarka ahna waa "LB/In2", kaas oo ah "pound/square inch". Cutubkani wuxuu la mid yahay calaamadda heerkulka (F).

Intaa waxaa dheer, waxaa jira PA (Pascal, hal Newton ayaa ku taal hal mitir oo laba jibbaaran), KPA, MPA, BAR, tiirka biyaha milimitir, meerkuriga milimitir iyo cutubyo kale oo cadaadis ah.

1 Baar (BAR) = 0.1 MPa (MPA) = 100 Knaka (KPA) = 1.0197 kg/ sentimitir laba jibaaran

1 Cadaadiska jawiga caadiga ah (ATM) = 0.101325 MPa (MPA) = 1.0333 Bar (BAR)

Maadaama farqiga cutubku aad u yar yahay, waad xasuusan kartaa tan:

1 Bar (BAR) = 1 Cadaadiska jawiga caadiga ah (ATM) = 1 kg/sentimitir laba jibbaaran = 100 kiilo (KPA) = 0.1 MPa (MPA)

Beddelka PSI waa sida soo socota:

1 Cadaadiska jawiga caadiga ah (ATM) = 14.696 rodol/inji 2 (PSI)

Xiriirka beddelka cadaadiska:

Cadaadiska 1 Bar (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)

Tiirka biyaha 1 mm (mmh2O) = 9.80665 Pa (PA)

1 Cadaadiska injineernimada jawiga = 98.0665 kite (KPA)

1 Knipa (KPA) = 0.145 rodol/inji 2 (PSI) = 0.0102 kg/cm 2 (kgf/cm2) = 0.0098 cadaadiska jawiga (ATM)

1 rodol oo xoog/inji ah 2 (PSI) = 6.895 kenta (KPA) = 0.0703 kg/cm 2 (kg/cm2) = 0.0689 Bar (bar) = 0.068 cadaadiska jawiga (ATM)

1 Cadaadiska jawiga jirka (ATM) = 101.325 Kenpa (KPA) = 14.696 rodol/inji 2 (PSI) = 1.0333 Bar (BAR)

Waxaa jira laba nooc oo kala ahwaalka: mid waa nidaamka "cadaadis magaceed" oo uu matalo Jarmalka (oo ay ku jirto waddankayga) heerkulka caadiga ah (Shiinaha waa 100 digrii Jarmalkana waa 120 digrii). Mid waa "nidaamka cadaadiska heerkulka" oo uu matalo Mareykanka heerkul gaar ah heerkul gaar ah.

Nidaamka heerkulka iyo cadaadiska ee Maraykanka, marka laga reebo 150LB oo ku salaysan 260 darajo, heerarka kale ee heerarka oo dhan waxay ku salaysan yihiin 454 darajo.

Waalka birta kaarboon ee 250-pound (150PSI = 1MPa) ee No. 25 wuxuu ahaa 260 digrii, cadaadiska la oggol yahayna wuxuu ahaa 1MPa, cadaadiska isticmaalka heerkulka qolkana aad buu uga weynaa 1MPa, qiyaastii 2.0MPa.

Sidaa darteed, guud ahaan, heerka cadaadiska magacaaban ee u dhigma heerka Mareykanka ee 150LB waa 2.0MPa, heerka cadaadiska magacaaban ee u dhigma 300LB waa 5.0MPa iwm.

Sidaa darteed, ma beddeli kartid cadaadiska magacaaban iyo heerka heerkulka iyadoo loo eegayo qaacidada isbeddelka cadaadiska.
