🔍 Key Concepts

• counterflow vs parallel-flow heat exchangers (how the two fluids move relative to each other) • the meaning of single-pass shell-and-tube (fluid in each side only travels from one end to the other once) • how temperature difference between hot and cold fluids is affected by same-direction vs opposite-direction flow

💭 Think About

• Picture the hot fluid moving inside the tubes from left to right. For each type (counterflow, parallel-flow, crossflow), where does the cold fluid enter and where does it leave? • Which arrangement keeps a higher temperature difference between the two fluids over the length of the exchanger: both moving the same way, or moving in opposite directions? • In a single-pass shell-and-tube exchanger, are the shell and tube flows able to be at right angles (crossing) to each other, or do they mostly run along the same axis?

✅ Before You Answer

• Be clear on the definition of counterflow: fluids moving in opposite directions along the same path. • Be clear on the definition of parallel-flow: fluids moving in the same direction along the same path. • Check whether a basic single-pass shell-and-tube design typically provides true crossflow, or primarily parallel/counterflow along the tube length.

Question 1 of 20

With regard to the relative flow patterns through the tubes and the shell of single pass shell-and-tube heat exchangers, what statement is true?

In a counterflow heat exchanger, the flow through the tubes and the flow through the shell are in opposite directions.

In a counterflow heat exchanger, the flow through the tubes and the flow through the shell are in the same direction.

In a crossflow heat exchanger, the flow through the tubes and the flow through the shell are in opposite directions.

In a parallel-flow heat exchanger, the flow through the tubes and the flow through the shell are in opposite directions.
