Abstract :
A new thermodynamic function, fugergy, g, has been defined to facilitate computation of the flow availability function, B. The definition of fugergy is dBT=RTo dln g where R is the gas constant and To is the external temperature. A formula for the computation of fugergy is also presented; tabulated values of the fugergy are obtained and presented as a function of: the reduced pressure, the reduced temperature and the reduced external temperature. Formulas for fugergy for the special case of a gas obeying the virial equation as well as Van der Waal´s equation are presented in the paper. Finally, the method to compute the changes in the flow availability using the fugergy tables is shown. This is illustrated by means of a numerical example
