Beddelka unugyada cadaadiska gaaska

Cadaadiska gaaska waa cadaadiska derbiga gaaska bixiyaha, taas oo ah muujinta macroscopic ee tiro badan oo unugyo ah oo si joogto ah u saameeya derbiga waana halbeeg muhiim ah oo loo isticmaalo in lagu qeexo xaaladda nidaamka. Sifooyin badan oo jirka iyo kiimikaad ah, sida barta, barta karkarinta, cadaadiska uumiga, ayaa ku dhawaad ​​dhammaan ku tiirsan cadaadiska. Cadaadisku sidoo kale waa arrin muhiim u ah daraasadda heerkulka kiimikaad iyo kinetics kiimikaad. Sidaa darteed, cabbirka cadaadiska ayaa muhiimad weyn leh.

Unugyada inta badan la isticmaalo waa: bar (bar), pascal (Pa). Cutubka cadaadiska, xagga fiisigiska, waxa loola jeedaa xoogga si toos ah ugu dhaqmaya dusha shay. Unugga waa Pascal (oo loo soo gaabiyo Pa Xarafka waa "Pa"). (Si adag u hadla, cutubka cadaadisku waa inuu noqdaa Newton N.) Cutubka cadaadisku waa Pascal, waana caado ah in lagu magacaabo cadaadiska nolosha) Shiinaha, waxaan guud ahaan ku qeexnaa cadaadiska gaaska "kilogram" (ma aha "jin). ”), halbeegga “kg•f/cm2″, waa kiilogaraam cadaadisku waa kiilooga awood ku shaqeeya sentimitir labajibbaaran.

1 Cadaadiska caadiga ah ee atmospheric = 760mmHg = 76cmHg = 1.01325×105Pa=10.336m tiirka biyaha. 1 cadaadiska jawiga caadiga ah

= 101325 N/㎡. (Sida caadiga ah 1 jawiga caadiga ah = 1.01×105Pa ee xisaabinta)

Haddii aad rabto inaad xisaabiso sax ah, xidhiidhku waa sida soo socota:

Xiriirka beddelka cadaadiska:

1 dyne sentimitir labajibbaaran (dyn/cm2) = 0.1 Pa (Pa)

1 torr = 133.322 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 xoogag rodol halkii inji labajibbaaran (psi) = 0.0102 kilomitir halkii sentimitir laba jibaaran (kgf/cm2) = 0.0098 atm (atm)

1 rodol halkii inji oo labajibbaaran (psi) = 6.895 kilopascals (kPa) = 0.0703 kilomitir halkii sentimitir laba jibaaran (kgf/cm2) = 0.0689 bar (bar) = 0.068 atm (atm)

1 Cadaadiska atmospheric jirka (atm) = 101.325 kilopascals (kPa) = 14.695949400392 rodol halkii inji (psi) = 1.01325 bar (bar)
