Ukuguqulwa kweeyunithi zoxinzelelo lwegesi

Uxinzelelo lwegesi luxinzelelo lodonga olunika igesi, oluyimbonakaliso ye-macroscopic yenani elikhulu leemolekyuli eziqhubekayo ezichaphazela udonga kwaye iparameter ebalulekileyo esetyenziselwa ukuchaza imeko yenkqubo. Iimpawu ezininzi zomzimba kunye neekhemikhali, ezifana nenqaku, indawo yokubilisa, uxinzelelo lomphunga, phantse zonke zixhomekeke kuxinzelelo. Uxinzelelo lukwayinto ebalulekileyo kwisifundo sekhemikhali thermodynamics kunye nekhemikhali kinetics. Ngoko ke, umlinganiselo woxinzelelo ubaluleke kakhulu.

Iiyunithi ezisetyenziswa ngokuqhelekileyo zezi: ibha (bar), ipascal (Pa). Iyunithi yoxinzelelo, kwifiziksi, ibhekisa kumandla asebenza ngokuthe nkqo kumphezulu wento. Iyunithi nguPascal (efinyeziweyo njengePa Unobumba "Pa"). (Ngokucacileyo, iyunithi yoxinzelelo kufuneka ibe nguNewton N.) Iyunithi yoxinzelelo yiPascal, kwaye isiko ukubiza uxinzelelo loxinzelelo ebomini) E-China, ngokuqhelekileyo sichaza uxinzelelo lwegesi njenge "kilogram" (kungekhona "jin". ”), iyunithi “kg•f/cm2″, yikhilogram yoxinzelelo yikhilogram yamandla asebenza kwisikwere sesentimitha.

1 Uxinzelelo oluqhelekileyo lwe-atmospheric = 760mmHg = 76cmHg = 1.01325 × 105Pa = 10.336m ikholamu yamanzi. I-1 yoxinzelelo oluqhelekileyo lwe-atmospheric

= 101325 N/㎡. (Ngokuqhelekileyo i-1 standard atmosphere = 1.01×105Pa kwizibalo)

Ukuba ufuna ukwenza ubalo oluchanekileyo, ubudlelwane buhamba ngolu hlobo lulandelayo:

Ubudlelwane botshintsho loxinzelelo:

I-dyne eyi-1 kwisikwere sesentimitha (dyn/cm2) = 0.1 Pa (Pa)

1 torr = 133.322 Pa

I-1 millimeter ye-mercury (mmHg) = 133.322 Pa (Pa)

Ikholamu yamanzi eyi-1 mm (mmH2O) = 9.80665 Pa (Pa)

I-1 yobunjineli yoxinzelelo lwe-atmospheric = 98.0665 kilopascals (kPa)

I-1 kilopascal (kPa) = 0.145 imikhosi yeponti nge-intshi yesikwere (psi) = 0.0102 kilogram yamandla kwisikwere sesentimitha (kgf/cm2) = 0.0098 atm (atm)

I-1 pound force per square intshi (psi) = 6.895 kilopascals (kPa) = 0.0703 kilogram force per square centimeter (kgf/cm2) = 0.0689 ibha (bar) = 0.068 atm (atm)

1 Uxinzelelo lwe-atmospheric yomzimba (atm) = 101.325 kilopascals (kPa) = 14.695949400392 amandla eeponti nge-intshi yesikwere (psi) = 1.01325 ibha (bar)
