🔍 Key Concepts

• NPSH (Net Positive Suction Head) and how it affects centrifugal pump capacity • The effect of air or vapor in the suction line or casing of a centrifugal pump • How packing gland sealing and hotwell level influence pump suction conditions

💭 Think About

• For each choice, ask: does this condition make it harder or easier for liquid to enter the eye of the impeller? • Consider which option could introduce air/vapor or reduce effective suction pressure, causing loss of prime or cavitation. • Think about which options would actually improve suction conditions versus those that would disturb normal condensate flow.

✅ Before You Answer

• Verify which options would increase NPSH (these usually help, not hurt, capacity). • Identify any option that could allow air or vapor into the pump casing or suction, which can severely reduce output. • Check which condition would change the seal around the pump shaft and possibly affect leakage or air entry.
