Question 1 of 27070

Reduced capacity, accompanied by vibration and noise at the suction of a centrifugal pump, results from cavitation in the fluid being pumped. Cavitation describes the formation of __________.

🔍 Key Concepts

• Centrifugal pump operation and what happens at the suction when inlet pressure is too low • Definition of cavitation in fluids and how bubbles/voids form and collapse • Difference between cavitation and other phenomena like water hammer or fluid friction

💭 Think About

• Think about what physically forms inside the liquid when local pressure drops below the vapor pressure of the fluid. • Which choice describes something that can cause vibration and noise as it forms and then collapses inside the pump? • Which options are specific technical effects in piping (like sudden valve closure) rather than the basic definition of cavitation itself?

✅ Before You Answer

• Verify which option directly matches the standard definition: "cavitation is the formation of ..." in a liquid when local pressure falls too low. • Eliminate any answers that describe results or separate phenomena (like shock waves in pipes) instead of what is actually being formed. • Make sure the choice you pick could reasonably exist right at the pump suction under low-pressure conditions.
