EOS_Tmin, EOS_Tmax and EOS

EOS_Tmin, EOS_Tmax and EOS_Pmax

These functions require only the name of an EES substance. The EES substance can be directly entered with our without surrounding single quote marks. Alternatively, a string variable, e.g., R$, can be used.

EOS_Tmin and EOS_Tmax return the minimum and maximum temperatures, respectively, allowed by the equation of state (EOS) for the specified substance. The returned values will be provided in the unit system specified in the EES program.

EOS_Pmax returns the maximum pressure allowed by the equation of state. The minimum pressure is usually zero.

These functions can be used for all substances, including Real and Ideal Gas substances, Solutions, Psychrometrics, NASA fluids and Incompressible substances.

Note that there is no maximum pressure for ideal gases and incompressible substances and so 99999 is returned.

Some Incompressible substances properties may have a temperature limits specific to that property. These information is not included in the EOS_Tmin and EOS_Tmax functions.

Example:

$UnitSystem SI C kPa

T_max=EOS_Tmax(CarbonDioxide)

{Solution

T_max=826.9 [C]
