Shimansky equation
In thermodynamics, the Shimansky equation describes the temperature dependence of the heat of vaporization (also known as the enthalpy of vaporization or the heat of evaporation): L = L 0 tanh ( L T C L 0 T ) {\displaystyle L=L_{0}\tanh \left({\frac {LT_{C}}{L_{0}T}}\right)} where: L is the latent heat of vaporization at the temperature T, TC is the critical temperature, L0 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.
