On completion of this chapter a student should be able to:

• Describe the three common types of heat exchanges described in the chapter.

• Calculate the log mean temperature difference (ΔT_{lm}) for counter/parallel flow heat exchangers.

• Calculate the correction factor (F_{T}) to account for the effect of multi-pass heat exchangers.

• Define and calculate the heat exchanger effectiveness factor (ε)

• Define what is meant by the terms mixed and unmixed as applied to a cross-flow exchanger.

• Calculate and define the effect that fouling has on the overall heat transfer coefficient.

• Preform a simple thermal design of a double pipe heat exchanger.
