Therefore in this example the manufacturers recommended weight of magnesium anodes would be 14kg to 20kg. Luckily anodes are sold by weight. Common sizes are 1.5kg, 2.5kg and 3.5kg ingots for standard weld-on canal boat anodes.nodes will offer protection based on the Noble Series of metals. The theory is that by attaching a piece of metal to the hull that is more reactive than the hull itself then this piece of metal will corrode first. For our inland waters we use sacrificial magnesium anodes for protection.
Pure water is a poor conductor of electricity while fresh water or tap water may be said to be a modest conductor and salt water has a much higher conductivity than fresh wate â¦ r. The electrical conductivity of water, both pure water and water with dissolved salts, is simpler to measure than to explain.
Silver has the highest conductivity of any metals: 63 x 10 6 S/m. Water conductivity. Pure water is not a good conductor of electricity. Ordinary distilled water in equilibrium with carbon dioxide of the air has a conductivity of about 10 x 10 -6 W -1 *m -1 (20 dS/m).Because the electrical current is transported by the ions in solution, the conductivity increases as the concentration of ions increases.Thus conductivity increases as water dissolved ionic species. Ultra pure water 5.5 Â· 10 -6 S/m. Drinking water 0.005 â 0.05 S/m.ilver has the highest conductivity of any metals: 63 x 10 6 S/m. Water conductivity. Pure water is not a good conductor of electricity. Ordinary distilled water in equilibrium with carbon dioxide of the air has a conductivity of about 10 x 10 -6 W -1 *m -1 (20 dS/m).
