Kutembenuka kwa magawo amagetsi a gasi

Kuthamanga kwa gasi ndiko kukakamiza kwa khoma la opereka gasi, komwe ndi chiwonetsero chachikulu cha mamolekyu ambiri omwe amakhudza khoma ndipo ndi gawo lofunikira lomwe limagwiritsidwa ntchito pofotokoza momwe dongosololi lilili. Zambiri zakuthupi ndi zamankhwala, monga mfundo, mfundo yowira, kuthamanga kwa nthunzi, pafupifupi zonse zimadalira kupanikizika. Kupanikizika ndi chinthu chofunikiranso pakuphunzira za chemical thermodynamics ndi kinetics zamankhwala. Choncho, kuyeza kupanikizika ndi kofunika kwambiri.

Magawo omwe amagwiritsidwa ntchito kwambiri ndi: bar (bar), pascal (Pa). Chigawo cha pressure, mu physics, chimatanthawuza mphamvu yomwe imagwira ntchito molunjika pamwamba pa chinthu. Chigawocho ndi Pascal (chidule cha Pa The letter is “Pa”). (Kulankhula kwenikweni, unit of pressure iyenera kukhala Newton N.) Chigawo cha kupanikizika ndi Pascal, ndipo ndi chizolowezi kutcha kupanikizika kwa moyo m'moyo) Ku China, kawirikawiri timalongosola kupanikizika kwa gasi monga "kilogram" (osati "jin). ”), unit “kg•f/cm2″, ndi kilogalamu ya kupanikizika ndi kilogalamu ya mphamvu yogwira ntchito pa sikweya sentimita.

1Standard atmospheric pressure = 760mmHg = 76cmHg = 1.01325×105Pa = 10.336m chigawo chamadzi. 1 mulingo wokhazikika wa mumlengalenga

= 101325 N/㎡. (Kawirikawiri 1 standard atmosphere = 1.01×105Pa powerengera)

Ngati mukufuna kuwerengera ndendende, ubalewu uli motere:

Ubale wotembenuka mtima:

1 dyne per square centimeter (dyn/cm2) = 0.1 Pa (Pa)

1 torr = 133.322 Pa

1 millimeter ya mercury (mmHg) = 133.322 Pa (Pa)

Mzere wa madzi 1 mm (mmH2O) = 9.80665 Pa (Pa)

1 engineering atmospheric pressure = 98.0665 kilopascals (kPa)

1 kilopascal (kPa) = 0.145 pounds mphamvu pa square inch (psi) = 0.0102 kilogram mphamvu pa square centimita (kgf/cm2) = 0.0098 atm (atm)

1 pounds force per square inch (psi) = 6.895 kilopascals (kPa) = 0.0703 kilogram mphamvu 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 force per square inch (psi) = 1.01325 bar (bar)
