Abstract
Static and dynamic experiments were made on brass tube plates and tube ends of condensers to determine the current distribution on them in sea water. Factors evaluated in this connection include effect of water velocity, effect of coatings, effect of temperature, and effect of composition of the anode and tube materials. It was found that most of the galvanic current flowing from ferrous components (or a steel anode) to a non-ferrous condenser tube sheet flowed to the tubes with only a small proportion going to the tube plate. A zinc alloy anode provided a much higher current than a steel anode to both an Admiralty brass tube and an aluminum brass tube.
