🔍 Key Concepts

• Centrifugal pump operation – what happens at the eye (suction side) of the impeller • Pressure vs. vaporization – what happens to liquid when local pressure drops very low • Difference between mechanical wear, chemical attack, and vapor bubble collapse on metal surfaces

💭 Think About

• Think about what conditions exist at the suction eye of a centrifugal pump: is the pressure high or low, and how could that affect the liquid? • Which phenomenon creates tiny bubbles that form and then violently collapse against the metal surface, causing small pits? • Which options are more likely to cause smooth wear or general thinning of metal, and which one is known for localized, crater-like pitting in high-velocity liquid flow areas?

✅ Before You Answer

• Identify which choice is specifically associated with vapor bubble formation and collapse in pumps and propellers • Separate in your mind: electrical/chemical action vs. mechanical erosion vs. vapor bubble damage • Visualize the damage pattern: is it uniform wear, general rusting, or sharp, localized pits concentrated in the suction/low-pressure zones?
