Information
This models computes the temperature Th for predefined specific enthalpy h1 via numerical inversion of function Modelica.Media.Incompressible.TableBased.h_T.
The specific enthalpy h2 is computed as check variable from temperature Th and must be identical to h1.
In an analogous manner, the temperature Ts is computed for predefined specific entropy s1 via numerical inversion of function Modelica.Media.Incompressible.TableBased.s_T.
The specific entropy s2 is computed as check variable from temperature Ts and must be identical to s1.
The numerical computation of the inverse function is performed by function Modelica.Math.Nonlinear.solveOneNonlinearEquation in both cases.
