Late to the party but anyway: Further to atotiace's post on 7 October: If the pressure is below the saturation pressure then the substance is superheated vapour. Only when the pressure corresponds exactly to the saturation temperature is it possible for there to be a mixture of liquid and vapour.

A cubic metre of liquid inflow adds 1/0.000795 kilograms = 1257.86 As that cubic metre leaves as vapour to make room for the liquid out goes 1/0.01872 kilograms = 53.42 The net effect is to add 1204.44 to the trapped mass for every 1257.86 of inflow. So to add the 72.18 noted upthread...
