🔍 Key Concepts

• Centrifugal pump pressure terms along the flow path • Difference between suction side and discharge side of a pump • Meaning of total head vs individual heads

💭 Think About

• Think about where the liquid is just before it actually enters the impeller—what part of the system is that, and what do we usually call the pressure there? • Which of these terms clearly describes pressure on the outlet side of the pump, and which describes pressure on the inlet side? • How would you combine suction and discharge pressures to describe the overall energy added by the pump?

✅ Before You Answer

• Identify which choice refers specifically to the inlet (low‑pressure) side of the pump • Eliminate any term that clearly includes both suction and discharge in one value • Make sure the term you select is commonly used for pressure or energy level at pump entrance, not overall pump performance
