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 Poynting Factor?
Poynting Factor calculator uses Poynting Factor = exp((-Volume of Liquid Phase*(Pressure-Saturated Pressure))/([R]*Temperature)) to calculate the Poynting Factor, The Poynting factor formula is defined as the function of volume of liquid phase of a component, pressure, saturated pressure and temperature. Poynting Factor is denoted by P.F. symbol.
How to calculate Poynting Factor using this online calculator? To use this online calculator for Poynting Factor, enter Volume of Liquid Phase (Vl), Pressure (P), Saturated Pressure (Psat) & Temperature (T) and hit the calculate button. Here is how the Poynting Factor calculation can be explained with given input values -> 0.554252 = exp((-120*(38.4-20))/([R]*450)).
