In heat exchangers, seawater pressure should be maintained lower than freshwater pressure to __________.

Question 1 of 27070

In heat exchangers, seawater pressure should be maintained lower than freshwater pressure to __________.

🔍 Key Concepts

• Pressure differential between seawater and freshwater sides of a heat exchanger • What happens when a tube or gasket leaks in a cooler • Difference between contamination risk and equipment wear/efficiency issues

💭 Think About

• If a leak develops between the seawater and freshwater sides, which fluid will naturally flow into the other based on pressure? • Which side of the system must be kept clean and uncontaminated for engine and machinery protection? • Which of the choices describes a safety/protection reason rather than a maintenance/efficiency benefit?

✅ Before You Answer

• Identify which side (seawater or freshwater) is the closed, critical system for machinery cooling • Decide which consequence is most serious if the pressure relationship is wrong: scaling, erosion, pump load, or contamination • Confirm that the chosen option directly depends on seawater pressure being lower than freshwater pressure, not just on good operation in general

Question 1 of 27070

In heat exchangers, seawater pressure should be maintained lower than freshwater pressure to __________.

eliminate scaling problems on the saltwater side

reduce erosion of heat exchanger surfaces

ease the load on the saltwater service pump

prevent contamination should leaks develop
