Question 1 of 27070

The differential temperature of the main condenser circulating water will be affected by __________. decrease in circulating pump pressure degree or amount of scaling or fouling

🔍 Key Concepts

• Main condenser heat transfer depends on water flow rate and cleanliness of heat transfer surfaces • Effect of circulating pump pressure on actual water flow through the condenser tubes • How scaling or fouling changes overall heat transfer coefficient and temperature difference

💭 Think About

• If the circulating pump pressure decreases, what happens to the actual water flow rate and its ability to pick up heat? Would that increase, decrease, or not change the temperature rise through the condenser? • If the tubes are scaled or fouled, does heat transfer become easier or harder? How would that change the temperature difference between inlet and outlet cooling water? • Think about an energy balance: the same amount of steam must be condensed. How can the condenser achieve this if water flow is reduced, or if heat transfer area is partially blocked?

✅ Before You Answer

• Clarify that differential temperature means outlet water temperature minus inlet water temperature across the condenser • Consider whether reduced water flow tends to increase or decrease the temperature rise for a given heat load • Consider whether more fouling tends to increase or decrease the temperature rise for a given heat load
