In this Section are presented sets of equations and graphs for simple heat exchanger configurations and for a set of shell-and-tube exchangers defined using the nomenclature of the TEMA Handbook. Descriptive material, comments on proper usage and limiting points are also included with each specific configuration. The topics covered are:
