🔍 Key Concepts

• Net Positive Suction Head (NPSH) definition and purpose • Relationship between NPSH and cavitation prevention in centrifugal pumps • How vapor pressure of the liquid affects pump suction conditions

💭 Think About

• Ask yourself: NPSH is the amount of energy (or head) available at the pump suction above what specific pressure condition that would cause the liquid to vaporize? • Which of the choices is directly related to when water will start forming vapor bubbles at a given temperature? • Which items in the choices are pump design/operating parameters, and which describes a thermodynamic property of the liquid itself?

✅ Before You Answer

• Be clear on the difference between pump characteristics (like speed, capacity, impeller geometry) and fluid properties (like vapor pressure). • Verify that NPSH is expressed as a head (usually in feet or meters) above a reference pressure level where cavitation would begin. • Confirm which option represents the condition at which water changes from liquid to vapor at a given temperature.
