Phetoho ea likarolo tsa khatello ea khase

Khatello ea khase ke khatello ea lebota la mofani oa khase, e leng pontšo ea macroscopic ea palo e kholo ea limolek'hule tse tsoelang pele ho ama lerako 'me ke parameter ea bohlokoa e sebelisetsoang ho hlalosa boemo ba tsamaiso. Lintho tse ngata tsa 'mele le lik'hemik'hale, tse kang ntlha, ntlha e belang, khatello ea mouoane, hoo e ka bang tsohle li itšetlehile ka khatello. Khatello e boetse ke ntlha ea bohlokoa thutong ea lik'hemik'hale tsa thermodynamics le lik'hemik'hale tsa lik'hemik'hale. Ka hona, tekanyo ea khatello ke ea bohlokoa haholo.

Liyuniti tse sebelisoang hangata ke: bar (bar), pascal (Pa). Karolo ea khatello, ho fisiks, e bolela matla a sebetsang ka ho otloloha holim'a ntho. Yuniti ke Pascal (e khutsufalitsoeng e le Pa Lengolo ke “Pa”). (Ha e le hantle, karolo ea khatello e lokela ho ba Newton N.) Sehlopha sa khatello ke Pascal, 'me ke tloaelo ho bitsa khatello ea khatello bophelong) Chaena, ka kakaretso re hlalosa khatello ea khase e le "kilogram" (eseng "jin". ”), unit “kg•f/cm2″, ke k’hilograma ea khatello ke k’hilograma ea matla e sebetsang ka lisenthimithara tse sekoere.

1 Khatello e tloaelehileng ea sepakapaka = 760mmHg = 76cmHg = 1.01325 × 105Pa = 10.336m kholomo ea metsi. 1 khatello e tloaelehileng ea sepakapaka

= 101325 N/㎡. (Hangata sebaka se le seng se tloaelehileng = 1.01×105Pa ka lipalo)

Haeba u batla ho etsa lipalo hantle, kamano e tjena:

Kamano ea phetoho ea khatello:

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

1 torr = 133.322 Pa

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

1 mm kholomo ea metsi (mmH2O) = 9.80665 Pa (Pa)

Khatello ea sepakapaka e 1 = 98.0665 kilopascals (kPa)

1 kilopascal (kPa) = 0.145 pounds force per square inch (psi) = 0.0102 kilogram force per square centimeter (kgf/cm2) = 0.0098 atm (atm)

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

1 Khatello ea 'mele ea sepakapaka (atm) = 101.325 kilopascals (kPa) = 14.695949400392 matla a lik'hilograma ka lisenthimithara tsa lisekoere (psi) = 1.01325 bar (bar)
