Definition

relation between heat content and latent heat content in a binary mixture undergoing a phase transition, expressed by

$S t e = c_{p} Δ T / Q$ ; where

$c_{p}$ :: is specific heat capacity at constant pressure (ISO 80000-5: Thermodynamics),

$Δ T$ :: is difference of thermodynamic temperature $T$ (ISO 80000-5: Thermodynamics) between the phases, and

$Q$ :: is quotient of latent heat of phase transition (ISO 80000-5: Thermodynamics) and mass (ISO 80000-4: Mechanics)

relation entre l'enthalpie et l'enthalpie latente dans un système binaire subissant une transition de phase, exprimée par:

$S t e = c_{p} Δ T / Q$ ; où

$c_{p}$ :: est la capacité thermique massique à pression constante (ISO 80000-5: Thermodynamics);

$Δ T$ :: est la différence de température thermodynamique $T$ (ISO 80000-5: Thermodynamics) entre les phases; et

$Q$ :: est le quotient de la chaleur latente de transition de phase (ISO 80000-5: Thermodynamics) par la masse (ISO 80000-4: Mechanics)
