🔍 Key Concepts

• Net positive suction head (NPSH) and how temperature affects water vaporization at the pump suction • Effect of a recirculating (bypass) line on actual suction flow to the pump • Relationship between suction head pressure and pump ability to maintain prime (suction)

💭 Think About

• Which choice would reduce the effective pressure or flow at the pump suction so that the pump could lose its prime? • How does increasing water temperature affect the likelihood of flashing to steam at low pressure areas like the pump eye? • What happens to suction conditions if too much of the pumped water is being sent back to the tank instead of forward to the boiler?

✅ Before You Answer

• Verify which conditions reduce NPSH available to the pump, making cavitation or loss of suction more likely • Check which options increase rather than decrease suction head or help pump operation, so they can be ruled out • Consider whether each option would make the pump more likely to draw in vapor/air instead of solid water at its suction
