Description

Calculates superheated steam properties based on the steam tables, IF97 formulation (IAPWS-IF97).

Returns properties at the state point (T,P)(T,P) — enthalpy, entropy, and specific heat—plus Psat(T)P_{sat}(T) and Tsat(P)T_{sat}(P) for reference and superheat checking.

Thermodynamic functions are evaluated directly:

h=h(T,P),s=s(T,P),cp=cp(T,P).h = h(T,P), \quad s = s(T,P), \quad c_p = c_p(T,P).
