Question 1 of 27070

A main condenser utilizing a scoop for the circulation of sea water must be constructed as a __________.

🔍 Key Concepts

• Main condenser scoop circulation and how seawater enters when the ship is moving • Difference between single-pass, two-pass, and heat flow direction (counterflow vs parallel flow) • Why designers might need more seawater velocity through the tubes when there is no pump forcing flow

💭 Think About

• Think about what happens to seawater velocity in the condenser if it only flows once straight through versus turning and going back through again. • Consider why a scoop system, which relies on ship speed instead of a pump, might need a particular flow arrangement to maintain good heat transfer. • Ask yourself which of the four options describes how many times the seawater travels through the tube bundle, versus the direction of flow relative to the steam.

✅ Before You Answer

• Make sure you separate number of passes (single vs two-pass) from direction of flow (counterflow vs parallel). • Consider how a scoop system depends on ship’s forward motion and what arrangement keeps tube-side velocity high enough. • Verify which of the listed options is commonly associated with scoop-type main condensers in marine steam plants.
