🔍 Key Concepts

• Sacrificial anodes (zincs) on shipboard condensers and heat exchangers • How dissimilar metals in seawater can create a galvanic cell • Difference between scaling, turbulence, air pockets, and electrolysis in seawater systems

💭 Think About

• Think about what happens when seawater flows through a metal condenser waterbox made from one metal, with tubes made from another metal. • Ask yourself: why would engineers purposely install a softer metal (zinc) that will slowly waste away? What problem is that meant to solve? • Consider which answer choices describe a chemical/electrical corrosion problem versus flow or deposit problems.

✅ Before You Answer

• Identify which option is related to corrosion caused by electrical/chemical action in seawater systems. • Eliminate the choices that deal only with flow characteristics (movement of water, mixing, pockets of air). • Recall that sacrificial zincs are designed to be the first metal to corrode, in order to protect the more important metal parts of the condenser.
