Heat Exchanger Analysis - Heat Exchanger Calculation. Heat exchangers are commonly used in industry, and proper design of a heat exchanger depends on many variables. In the analysis of heat exchangers, it is often convenient to work with an overall heat transfer coefficient, known as a U-factor.The U-factor is defined by an expression analogous to Newton's law of cooling. Plate heat exchangers (PHE) are of primary importance for many technical applications. To use PHE effectively it is necessary to calculate the pressure drop correctly.
