In a regenerative rankine cycle, how in the fuck does one determine whether the turbine output is a saturated mixture or superheated vapor? Up to this point, turbines have always been taken as outputting just under the saturation curve. The text now depicts only examples of it being superheated vapor, but the solutions manual (and hence the problems) seemingly arbitrarily involve above and/or below the saturation curve with absolutely no explanation, as if it were given in the problem statement (it wasn't).
