🔍 Key Concepts

• effects of high fluid velocity on metal tubes in a heat exchanger • difference between erosion, fouling (deposits), and mechanical shock problems • where velocity-related damage is most likely to occur in a tube bundle

💭 Think About

• Ask what happens to metal surfaces when a liquid moves past them too fast, especially at bends, inlets, or restrictions. • Consider which problem is usually caused by fluid moving too slowly rather than too fast. • Think about which of the choices is most directly tied to long‑term wear of the inner tube surface rather than a sudden impact or structural distortion.

✅ Before You Answer

• Identify which option describes gradual loss of tube wall material due to scouring action. • Identify which option describes buildup of scale or deposits that is worse at low velocities. • Eliminate any choices that are primarily associated with sudden pressure surges or uneven thermal expansion, not continuous high velocity.
