With regard to the number of passes through the tubes of shell-and-tube heat exchangers, what statement is true?

🔍 Key Concepts

• Shell-and-tube heat exchanger flow paths – how the tube-side fluid travels from inlet to outlet • Difference between single-pass, two-pass, and four-pass tube arrangements • Location of inlet and outlet headers (channel covers) for different numbers of passes

💭 Think About

• Visualize the tube bundle: if the fluid must make more than one pass through the tubes, what has to happen at the ends to turn the flow around? • For a single-pass exchanger, where would the inlet and outlet logically need to be so the fluid only goes straight through once? • For multiple-pass designs, think about whether the inlet and outlet can be at the same end or must be at opposite ends to allow the required number of passes.

✅ Before You Answer

• Sketch a simple single-pass exchanger and mark where inlet and outlet must be located for one straight-through flow path. • Then sketch a two-pass exchanger and show how the flow reverses direction; check whether that forces inlet and outlet to be at the same end or opposite ends. • Verify which arrangements would make it physically impossible for the fluid to complete the stated number of passes through the tube bundle.

With regard to the number of passes through the tubes of shell-and-tube heat exchangers, what statement is true?

In two-pass and four-pass heat exchangers, the inlet and outlet tube-side fluid connections are at the same end.

In single-pass and two-pass heat exchangers, the inlet and outlet tube-side fluid connections are at opposite ends.

In single-pass and two-pass heat exchangers, the inlet and outlet tube-side fluid connections are at the same end.

In two-pass and four-pass heat exchangers, the inlet and outlet tube-side fluid connections are at opposite ends.
