Z
  • parandustegur, mis väljendab numbriliselt reaalse gaasi käitumise hälvet ideaalse gaasi seadusest antud rõhul ja temperatuuril
  • parandustegur, mis võtab arvesse tegeliku gaasiteguri kõrvalekallet universaalsest
  • correction factor for the deviation of the real gas constant from the universal one
  • ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure
  • correction factor expressing numerically the deviation from the ideal gas law of the behavior of real gas at given pressure and temperature conditions
kokkusurutavustegur
Usage examples
  • Kokkusurutavustegur gaasi puhul on määratletud kui gaasi molaarmahu ja ideaalse gaasi molaarmahu suhe samal temperatuuril ja rõhul ehk määratletud valemiga Z = pM/ρRT, kus R, molaarne gaasikonstant, on võrdne 8,314 3 J/(mol·K).
Z symbol
compressibility factor preferred
Usage examples
  • Compressibility factor is defined by the formula Z = pM/ρRT, where R, the molar gas constant, equals 8,314 3 J/(mol.K).

  • tegur, mis on kasutusel vedeliku kokkusurutavuse arvestamisel
  • coefficient used to take into account the compressibility of the fluid
kokkusurutavustegur
Usage examples
  • Kokkusurutavustegur on võrdne ühega, kui vedelikku peetakse kokkusurumatuks (vedelaks) ja see on väiksem kui üks, kui vedelik on kokkusurutav (gaasiline vedelik).
paisumistegur
ε symbol
expansibility factor preferred
Usage examples
  • The expansibility factor is equal to unity when the fluid is considered incompressible (liquid) and is less than unity when the fluid is compressible (gaseous).
