What is Duhem’s Theorem?
For any closed system formed from known amounts of prescribed chemical species, the equilibrium state is completely determined when any two independent variables are fixed. The two independent variables subject to specification may in general be either intensive or extensive. However, the number of independent intensive variables is given by the phase rule. Thus when F = 1, at least one of the two variables must be extensive, and when F = 0, both must be extensive.
How to Calculate Saturated Fugacity Coeff. using Poynting Factor Correlation and Fugacity of Liq. Phase Species?
Saturated Fugacity Coeff. using Poynting Factor Correlation and Fugacity of Liq. Phase Species calculator uses Saturated Fugacity Coefficient of Species = Fugacity of Liquid Phase Species/(Saturated Pressure*exp((-Volume of Liquid Phase*(Pressure-Saturated Pressure))/([R]*Temperature))) to calculate the Saturated Fugacity Coefficient of Species, The Saturated Fugacity Coeff. using Poynting Factor Correlation and Fugacity of Liq. Phase Species formula is defined as the function of fugacity of the liquid phase of a species, saturated pressure, the volume of the liquid phase of a component, pressure, saturated pressure and temperature. Saturated Fugacity Coefficient of Species is denoted by ϕsat symbol.
