bc for supersaturated steam

Peter

Hi, I have to compute a steam flow that is supersaturated at the outlet. As I wanted to set partial pressure at the outlet I switched the outled condition to "average static pressure" but the values of enthalpy and entropy differ from the ones I expected. I asssume that the outlet condition "static pressure" refers to the saturation pressure instead of the partial pressure. So could someone tell me which kind of pressure the outlet condition refers to and -if saturation pressure is set- is it possible to set partial pressure? Thanks a lot
