Question 1 of 27070

Which of the water supplies listed below is typically used as a cooling medium for the gland exhaust condenser, intercondenser, and after condenser of an air ejector unit?

🔍 Key Concepts

• Think about which water source is most readily available in large quantities on most ships for continuous cooling duty. • Consider the cleanliness and treatment requirements of potable water and distilled water, and whether engineers want these in direct contact with condensers that may foul. • Remember that air ejector condensers are part of the main condenser/cooling system and usually share the same cooling medium.

💭 Think About

• Which of these water types would be too valuable or require too much protection to use as a primary cooling medium that may become contaminated? • On an oceangoing vessel, which water source is abundant enough to handle a continuous heat load from multiple condensers? • Which water source is commonly circulated through shell‑and‑tube heat exchangers associated with the main condenser system?

✅ Before You Answer

• Eliminate any options that are normally reserved for drinking, cooking, and sanitation. • Eliminate options that are products of the main condenser/evaporator system, which engineers typically protect from contamination. • Ask yourself: in most engine room cooling systems, what water goes through the condenser tubes versus what water stays on the steam/condensate side?
