FUNDAMENTAL DEPENDENCE RELATIVE HUMIDITY OF TEMPERATURE AND ITS USABILITY IN THE THERMODYNAMICS OF SOIL WATER
The results of development physically-based models for describing the fundamental relationship between the relative humidity and the thermodynamic water potential on temperature (T) in the conditions of thermodynamic equilibrium are given. The final formula for the potential of moisture (Y) in the first (linear) approximation looks like: Y = Q - a T, where Q is specific heat of vaporization, а is physically reasonable parameter associated with the initial relative humidity of the air in the external thermodynamic reservoir (laboratory or environment). The experiments with simultaneous measurement of relative humidity and temperature by programmable automatic sensors «Hygrochron» DS1923 fully confirmed the adequacy of the proposed theoretical models. We discuss the possibility of their using in environmental sciences and engineering disciplines, in particular - to justify the new thermostatic method of quantitative estimation the water potential in soil and other dispersed systems.
