At the end of this lesson, you will be able to explain how heat is transferred from one substance to another using heat exchangers. In addition, you will be able to describe the basic differences between heat exchangers and their supporting equipment. • Describe how heat exchangers transfer heat from one substance to another • Define conductivity and explain its relationship to heat exchanger design • Define convection and explain its relationship to heat exchanger design • Identify different heat exchanger designs and how they function • Recall necessary supporting equipment for a heat exchanger
