  2. Enthalpy of vaporization - Wikipedia

    en.wikipedia.org/wiki/Enthalpy_of_vaporization

    Temperature-dependency of the heats of vaporization for water, methanol, benzene, and acetone. In thermodynamics, the enthalpy of vaporization (symbol ∆H vap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas.

    Here is a similar formula from the 67th edition of the CRC handbook. Note that the form of this formula as given is a fit to the Clausius–Clapeyron equation, which is a good theoretical starting point for calculating saturation vapor pressures:

    Another definition of the LHV is the amount of heat released when the products are cooled to 150 °C (302 °F). This means that the latent heat of vaporization of water and other reaction products is not recovered. It is useful in comparing fuels where condensation of the combustion products is impractical, or heat at a temperature below 150 ...

  7. Trouton's rule - Wikipedia

    en.wikipedia.org/wiki/Trouton's_rule

    Enthalpies of melting and boiling for pure elements versus temperatures of transition, demonstrating Trouton's rule. In thermodynamics, Trouton's rule states that the (molar) entropy of vaporization is almost the same value, about 85–88 J/(K·mol), for various kinds of liquids at their boiling points. [1]

  8. Droplet vaporization - Wikipedia

    en.wikipedia.org/wiki/Droplet_vaporization

    is the heat flux from the gas to the droplet surface (J.s −1) is the latent heat of evaporation of the species considered (J.kg −1) Analytical expressions for the droplet vaporization rate, ˙, and for the heat flux are now derived. A single, pure, component droplet is considered and the gas phase is assumed to behave as an ideal gas.

  9. Shimansky equation - Wikipedia

    en.wikipedia.org/wiki/Shimansky_equation

    L is the latent heat of vaporization at the temperature T, T C is the critical temperature, L 0 is the parameter that is equal to the heat of vaporization at zero temperature (T → 0), tanh is the hyperbolic tangent function. This equation was obtained in 1955 by Yu. I. Shimansky, at first empirically, and later derived theoretically.
