Saturation curve solver for arbitrary variables To solve for the internal energy of saturated steam at rho=3.6 kg/m3, use:

                        SatCurve<SpecificEnergy,Density> C;
                        SpecificEnergy u = C.solve(3.6 * kg_m3,SAT_STEAM);

Warning:

This function makes no allowance for expansion of water at temperatures close to zero, so you will get wrong temperatures in this region when solving for <xxx,v>
