Im trying to plot two points on an enthalpy$-$entropy $($h$-$s$)$ diagram for a steam cycle. The first point is the inlet steam after a superheater, with a temperature of $138\backslash$deg C and a pressure of $3\mathrm{.}34$ bar. The second point is after the turbine, which operates under an isentropic process, where the outlet conditions correspond to a condenser pressure of $0\mathrm{.}23$ bar and a condenser temperature of $43\backslash$deg C$.$ How can I determine the specific enthalpy and specific entropy for these two points, considering the isentropic process, to accurately place them on the h$-$s diagram?
