Shanduko yegasi pressure units

Kudzvanywa kwegasi ndiko kudzvanywa kwemadziro ekupa gasi, inova macroscopic kuratidzwa kwenhamba huru yemamorekuru anoramba achikanganisa madziro uye yakakosha parameter inoshandiswa kutsanangura mamiriro ehurongwa.Zvizhinji zvemuviri uye zvemakemikari zvimiro, senge point, kubikira poindi, mhute yekumanikidza, zvinenge zvese zvinotsamira.Dzvinyiriro zvakare chinhu chakakosha mukudzidza kwemakemikari thermodynamics uye kemikari kinetics.Nokudaro, kuyerwa kwekumanikidzwa kunokosha zvikuru.

Zvishandiso zvinowanzoshandiswa ndezvi: bar (bar), pascal (Pa).Chirevo chekumanikidza (unit of pressure) mufizikisi (fizikisi) zvinoreva simba rinoshanda rakatwasuka riri pamusoro pechinhu.Iyo unit ndiPascal (yakapfupikiswa sePa Tsamba iri "Pa").(Kunyatsotaura, chikwata chekumanikidzika chinofanira kunge chiri Newton N.) Chikamu chekumanikidza ndiPascal, uye itsika kudana dzvinyiriro muhupenyu) MuChina, tinowanzotsanangura kudzvinyirira kwegasi se "kilogram" (kwete "jin". ”), iyo unit “kg•f/cm2″, ikirogiramu yekumanikidza ikirogiramu yesimba rinoshanda pane sikweya centimita.

1Standard atmospheric pressure = 760mmHg = 76cmHg = 1.01325×105Pa = 10.336m mbiru yemvura.1 yakajairwa atmospheric pressure

= 101325 N/㎡.(Kazhinji 1 yakajairika mamiriro = 1.01 × 105Pa mukuverenga)

Kana iwe uchida kuita maverengero chaiwo, hukama hwakadai:

Pressure shanduko hukama:

1 dyne pa square centimita (dyn/cm2) = 0.1 Pa (Pa)

1 torr = 133.322 Pa

1 millimeter yemekiyuri (mmHg) = 133.322 Pa (Pa)

1 mm mbiru yemvura (mmH2O) = 9.80665 Pa (Pa)

1 engineering atmospheric pressure = 98.0665 kilopascals (kPa)

1 kilopascal (kPa) = 0.145 pound masimba pa square inch (psi) = 0.0102 kilogram simba pa square centimita (kgf/cm2) = 0.0098 atm (atm)

1 pound force per square inch (psi) = 6.895 kilopascals (kPa) = 0.0703 kilogram simba pa square centimita (kgf/cm2) = 0.0689 bar (bar) = 0.068 atm (atm)

1 Physical atmospheric pressure (atm) = 101.325 kilopascals (kPa) = 14.695949400392 pounds simba per square inch (psi) = 1.01325 bha (bha)
