Q

The outlet from an expansion tank of a closed fresh water cooling system should be piped to the __________.

🔍 Key Concepts

• Closed fresh water cooling system flow path: pump → engine jackets → heat exchanger → back to pump • Purpose of an expansion tank: to handle thermal expansion, keep the system full, and allow air to separate • Where lowest pressure exists in the cooling system (relative to the circulating pump)

💭 Think About

• First, sketch or visualize the normal direction of water flow through a closed jacket water system. Where does it start and where does it return? • Ask yourself: the expansion tank must ‘communicate’ with the system at a point that will stay flooded and not see excessive pressure. Which of these locations is safest from pressure surges? • Think about where you’d want any entrained air or expansion volume to go. Which line in the system is the best place to connect a tank that needs stable flow and pressure?

✅ Before You Answer

• Verify which component/line is on the suction side of the jacket water pump versus the discharge side • Check which choice would be exposed to higher, pulsating pressure and which would see more stable, lower pressure • Confirm that the point you choose would help keep the pump continuously flooded and the system completely full of water
