Vapor pressure

More information P/(Pa), 1 k ...

Notes

  • Values are given in terms of temperature necessary to reach the specified pressure.
  • Valid results within the quoted ranges from most equations are included in the table for comparison.
  • A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875).
  • Ref. SMI uses temperature scale ITS-48. No conversion was done, which should be of little consequence however.
  • The temperature at standard pressure should be equal to the normal boiling point, but due to the considerable spread does not necessarily have to match values reported elsewhere.
  • log refers to log base 10
  • (T/K) refers to temperature in Kelvin (K)
  • (P/Pa) refers to pressure in Pascal (Pa)
