Saturation Pressure Calculator Formula

The calculation of saturation pressure varies depending on the selected substance. The formulas used in the calculator are as follows:

  • Water: The saturation pressure of water is calculated using the Antoine equation:
    • P = exp(A - (B / (T + C))), where T is the temperature in Kelvin and A, B, and C are substance-specific constants.
  • Ethanol: The saturation pressure of ethanol is calculated using the Antoine equation:
    • P = exp(A - (B / (T + C))), where T is the temperature in Kelvin and A, B, and C are substance-specific constants.
  • Methanol: The saturation pressure of methanol is calculated using the Antoine equation:
    • P = exp(A - (B / (T + C))), where T is the temperature in Kelvin and A, B, and C are substance-specific constants.
