Air binding is potentially serious cause of excess head loss in water pipe lines flowing under less than atmospheric pressure; phenomenon of air binding and methods of control discussed, with emphasis on accumulation of air in sloping pipes; installations described are circulating water systems of steam-electric stations; principles are applicable to any water pumping station with similar profile.
