1. Introduction

3. CALCULATION OF CONCENTRIC TUBES HEAT EXCHANGERS

This section will explain the methodology of calculation of heat exchangers of concentric tubes or double tube. At the end of the section are two examples to see the implementation of various mathematical equations.

In general, the fluid is hot fluid 1 and 2 will be cold.
