Hey guys! Just wanted to inquire about the following relationship. Given a boiler and all the water content inside is above boiling point. Would the dryness factor (vapor quality) decrease or increase with pressure reduction. Example we start at 500 kPa then move down down to 400 kPa. Would the dryness factor increase or decrease. From the little calculation I know I estimated that the dryness factor would increase as pressure decreases. Indirect relationship. IF this is true what scientific explanations can be given for it. The only explanation I can think of is that high pressured gasses tend to liquefy. Thus if the pressure drops the dryness factor should increase until the temperature and pressure drops to a certain level.
