Ukuguqulwa kwamayunithi wokucindezela kwegesi

Ukucindezela kwegesi ukucindezela kodonga olunikeza igesi, okuwukubonakaliswa okukhulu kwenani elikhulu lama-molecule alokhu ethinta udonga futhi iyipharamitha ebalulekile esetshenziselwa ukuchaza isimo sohlelo. Izakhiwo eziningi ezingokomzimba namakhemikhali, njengephuzu, indawo ebilayo, ukucindezela komhwamuko, cishe zonke zincike ekucindezelweni. Ingcindezi nayo iyisici esibalulekile ocwaningweni lwe-chemical thermodynamics kanye ne-chemical kinetics. Ngakho-ke, ukukalwa kwengcindezi kubaluleke kakhulu.

Amayunithi asetshenziswa kakhulu yilawa: ibha (ibha), i-pascal (Pa). Iyunithi yokucindezela, ku-physics, ibhekisela kumandla asebenza ngokuma phezulu endaweni yento. Iyunithi ithi Pascal (efushanisiwe ngokuthi Pa Uhlamvu luthi “Pa”). (Uma sikhuluma ngokuqinile, iyunithi yokucindezela kufanele ibe ngu-Newton N.) Iyunithi yokucindezela i-Pascal, futhi kuyisiko ukubiza ingcindezi yokucindezela empilweni) E-China, ngokuvamile sichaza ukucindezela kwegesi ngokuthi "kilogram" (hhayi "jin ”), iyunithi “kg•f/cm2″, ikhilogremu yokucindezela iyikhilogremu yamandla asebenza kusentimitha yesikwele.

1Ingcindezi ye-atmospheric evamile = 760mmHg = 76cmHg = 1.01325×105Pa = 10.336m ikholomu yamanzi. 1 umfutho womoya ojwayelekile

= 101325 N/㎡. (Ngokujwayelekile umoya ojwayelekile ongu-1 = 1.01×105Pa ezibalweni)

Uma ufuna ukwenza isibalo esiqondile, ubudlelwano bumi kanje:

Ubudlelwano bokuguqulwa kwengcindezi:

I-dyne engu-1 ngesentimitha yesikwele (dyn/cm2) = 0.1 Pa (Pa)

1 i-torr = 133.322 Pa

Imilimitha engu-1 ye-mercury (mmHg) = 133.322 Pa (Pa)

1 mm ikholomu yamanzi (mmH2O) = 9.80665 Pa (Pa)

1 ubunjiniyela bengcindezi ye-atmospheric = 98.0665 kilopascals (kPa)

1 kilopascal (kPa) = 0.145 amabutho ephawundi nge-intshi yesikwele (psi) = 0.0102 kilogram force per square centimeter (kgf/cm2) = 0.0098 atm (atm)

Iphawundi elingu-1 intshi yesikwele ngayinye (psi) = 6.895 kilopascals (kPa) = 0.0703 kilogram force per square centimeter (kgf/cm2) = 0.0689 ibha (ibha) = 0.068 atm (atm)

1 Umfutho womzimba womkhathi (atm) = 101.325 kilopascals (kPa) = 14.695949400392 amandla amaphawundi ngeyintshi yesikwele (psi) = 1.01325 ibha (ibha)
